Computed tomography (CT) is a simple and useful method for monitoring during cryoablation; however, image quality is degraded by artifacts caused by the cryoprobe used during treatment. We evaluated the effectiveness of combining tilt scanning and single-energy metal artifact reduction (SEMAR) to improve image quality. A cryoprobe was inserted into an agar phantom, and CT scans were performed at various angles (0°, 5°, 10°, 15°, and 20°) with and without metal artifact reduction. The relative artifact index, calculated using the CT value standard deviation, was used to evaluate the intensity. The strongest tip artifacts occurred at 0°. The relative artifact index decreased with increasing tilt angles. The tilted scanning reduced artifacts extending beyond the cryoprobe tip, but SEMAR demonstrated a limited effect on artifact reduction. The tilted scanning method may be a useful approach for improving the image quality around the cryoprobe without increasing the exposure dose.

PURPOSE: Although preoperative marking is often required to accurately locate the targets for video-assisted thoracic surgery, target lesions can be identified intraoperatively without marking in some cases; however, the frequency and characteristics of these lesions remain unclear. Therefore, we aimed to retrospectively evaluate the need for a short hookwire for preoperative localization of small pulmonary lesions. MATERIALS AND METHODS: Computed tomography (CT)-guided short hookwire placement was performed for 176 lesions (mean diameter, 7.9 ± 3.5 mm) in 171 sessions prior to video-assisted thoracoscopic surgery. Placement was performed if one or more of the following CT findings were present: lesions (1) ≤ 10 mm in diameter; (2) ≥ 5 mm from the pleural surface, and (3) predominantly consisting of ground-glass opacity. The need for a hookwire for intraoperative lesion detection was retrospectively assessed based on surgical records. Factors associated with the absence of a hookwire for lesion detection were determined using univariate and multivariate analyses. RESULTS: Placement was successful in all cases; however, the hookwire was dislodged at the time of surgery in four lesions (2%). Among the remaining 172 lesions, thoracoscopic resection was performed using a hookwire as a landmark in 101 lesions (58.7%), whereas 71 lesions (41.3%) were detectable without a hookwire. Previous ipsilateral lung resection significantly increased the odds of not needing a hook wire (OR 4.24; P = 0.005). Larger target lesions (mean, 8.4 vs. 7.1 mm) and those located further from the pleura (mean, 13.3 vs. 8.0 mm) were associated with an increased need for hook wires. Multivariate analysis revealed that experienced surgeons required more hookwires compared to trainees (P = 0.029). Solid nodules did not require hookwires (P = 0.032). CONCLUSION: Shallow solid lesions in patients with a history of ipsilateral lung resection may not require hookwire placement during resection, even if they are small.

OBJECTIVE: The extent of resection (EOR) is an important prognostic factor for both low- and high-grade gliomas. Intraoperative MRI (iMRI) has been used to increase the EOR in glioma surgery. While a recent study reported differences between iMRI and early postoperative MRI (epMRI), their specific relationship to postoperative clinical symptoms remains unclear. This study aims to compare the differences between iMRI and epMRI in glioma surgery. METHODS: A retrospective assessment was conducted on 43 patients with glioma who underwent surgery with iMRI and for whom no additional resection was performed after iMRI. The study evaluated the discrepancies in EOR, surgically induced contrast enhancement (SICE), and diffusion-weighted imaging (DWI) abnormality between iMRI and epMRI. EOR was defined as gross-total resection (GTR), near-total resection, subtotal resection (STR), or partial resection (PR) for enhancing lesions, and GTR, STR, or PR for nonenhancing lesions. In addition, the relationship between postoperative neurological findings and iMRI findings was evaluated. RESULTS: Discrepancies in EOR were observed in 2 (11.1%) of 18 cases with nonenhanced lesions and 1 (4.0%) of 25 cases with enhanced lesions. The positive rate of SICE was 25.0% on iMRI and 67.9% on epMRI. Enhancement at the resection cavity was the most frequent pattern in both iMRI and epMRI. The positive rate of enhancement of the resection cavity was strongly increased on epMRI compared with iMRI, potentially mimicking residual tumor. The positive rate of DWI abnormality was 73% on iMRI and 89.2% on epMRI. Among the 10 patients who showed no DWI abnormality on iMRI, 6 exhibited DWI abnormality on epMRI (the late-developing group). Two patients developed new neurological deficits postoperatively, and both showed DWI abnormality on both iMRI and epMRI. No patient in the late-developing group developed postoperative neurological deficits. CONCLUSIONS: Overall, iMRI demonstrated more accurate EOR and less SICE compared with epMRI. Although the positive rate of DWI abnormality was lower on iMRI than on epMRI, the late-developing group showed no postoperative neurological deficits. Therefore, iMRI is more useful in assessing accurate EOR and detecting postoperative neurological deficits than epMRI.

Temporal bone computed tomography (CT) is frequently performed for pediatric patients with ear diseases. Advances in CT technology have improved diagnostic imaging quality, but reduction of radiation exposure remains a goal. We evaluated the potential for radiation dose reduction in temporal bone CT examinations using porcine ear ossicles and a photon-counting detector CT system. Three scans of the bilateral temporal bone were performed on each of three pig cadaver heads. In each of seven successive imaging sessions, the radiation dose was reduced by an additional one-seventh of the recommended dose (RD). Two board-certified radiologists independently scored the resulting images on a scale of 1 to 5 points, where 5 represented the image quality at the RD. Images scoring ≥4.5 points were considered acceptable. Noise was assessed in a 2-cm-diameter region near the ear ossicles, and standard deviation was measured for each of the seven decrements from the RD. As the radiation dose decreased, the noise progressively increased, and visual assessment scores progressively decreased. Acceptable image scores were obtained at six-sevenths (4.9), five-sevenths (4.8), four-sevenths (4.7), and three-sevenths (4.6) of the RD. Thus, acceptable porcine temporal bone CT images were obtained with a radiation dose reduction of approximately 50%.

Abstract

Background

Robotic needle insertion under CT guidance has been developed, but data on comparison with manual insertion are still lacking.

Purpose

To compare robotic versus manual needle insertion for CT fluoroscopy-guided intervention, primarily in terms of insertion accuracy.

Materials and Methods

This was a prospective study between May 2020 and March 2023 at a single site. The cohort comprised 22 patients undergoing CT (Aquilion One or Aquilion CX; Canon Medical Systems) fluoroscopy-guided biopsy, who were randomly allocated to either the robotic or manual group. The robot used (Zerobot; Medicalnet Okayama) is not yet commercially available. A biopsy introducer needle was inserted by 1 of 3 physicians using a remote-control robot in the robotic group, versus by 1 of 3 different physicians by hand in the manual group. The primary endpoint was needle insertion accuracy, which was defined as the 3-dimensional Euclidean distance between a predetermined target point and the needle tip after insertion. The non-inferiority of robotic insertion to manual one was then tested. Adverse events were evaluated. Statistical comparisons were made between the 2 groups.

Results

Technical success and pathological findings were confirmed in all patients of the 2 groups. The mean and SD of needle insertion were 4.8 mm ± 2.6 in the robotic group and 7.0 mm ± 3.1 in the manual group (P &lt; .001). The mean difference in accuracy between the 2 groups (robotic minus manual group) was −2.1 mm (95% CI, −4.7 to 0.4). Effective dose to physicians was zero in all cases in the robotic group, while median dose was 1.0 µSv in the manual group (P &lt; .001). Dose length product to patients was not significantly different between the 2 groups (P = .100). No major adverse events were observed.

Conclusion

Robotic needle insertion was non-inferior to manual insertion in terms of accuracy, while it effectively eliminated radiation exposure to physicians.

We developed a machine learning model for predicting prostate cancer (PCa) grades using radiomic features of magnetic resonance imaging. 112 patients diagnosed with PCa based on prostate biopsy between January 2014 and December 2021 were evaluated. Logistic regression was used to construct two prediction models, one using radiomic features and prostate-specific antigen (PSA) values (Radiomics model) and the other Prostate Imaging-Reporting and Data System (PI-RADS) scores and PSA values (PI-RADS model), to differentiate high-grade (Gleason score [GS] ≥ 8) from intermediate or low-grade (GS < 8) PCa. Five imaging features were selected for the Radiomics model using the Gini coefficient. Model performance was evaluated using AUC, sensitivity, and specificity. The models were compared by leave-one-out cross-validation with Ridge regularization. Furthermore, the Radiomics model was evaluated using the holdout method and represented by a nomogram. The AUC of the Radiomics and PI-RADS models differed significantly (0.799, 95% CI: 0.712-0.869; and 0.710, 95% CI: 0.617-0.792, respectively). Using holdout method, the Radiomics model yielded AUC of 0.778 (95% CI: 0.552-0.925), sensitivity of 0.769, and specificity of 0.778. It outperformed the PI-RADS model and could be useful in predicting PCa grades, potentially aiding in determining appropriate treatment approaches in PCa patients.

Abstract

Introduction:

Photon-counting computed tomography (CT) is equipped with an adaptive iterative reconstruction method called quantum iterative reconstruction (QIR), which allows the intensity to be changed during image reconstruction. It is known that the reconstruction conditions of CT images affect the analysis results when performing radiomic analysis. The aim of this study is to investigate the effect of QIR intensity on image quality and radiomic analysis of renal cell carcinoma (RCC).

Materials and Methods:

The QIR intensities were selected as off, 2 and 4. The image quality evaluation items considered were task-based transfer function (TTF), noise power spectrum (NPS), and low-contrast object specific contrast-to-noise ratio (CNR_LO). The influence on radiomic analysis was assessed using the discrimination accuracy of clear cell RCC.

Results:

For image quality evaluation, TTF and NPS values were lower and CNR_LO values were higher with increasing QIR intensity; for radiomic analysis, sensitivity, specificity, and accuracy were higher with increasing QIR intensity. Principal component analysis and receiver operating characteristics analysis also showed higher values with increasing QIR intensity.

Conclusion:

It was confirmed that the intensity of the QIR intensity affects both the image quality and the radiomic analysis.

This study retrospectively evaluated the computed tomography (CT) findings of idiopathic multicentric Castleman disease (iMCD) at a single center and compared the CT findings of iMCD-TAFRO with those of iMCD-non-TAFRO. CT images obtained within 30 days before diagnostic confirmation were reviewed for 20 patients with iMCD (8 men and 12 women, mean age 52.8 ± 12.3 years, range 25-74 years). Twelve patients were diagnosed with iMCD-TAFRO, five with iMCD-idiopathic plasmacytic lymphadenopathy, and three with iMCD-not otherwise specified. CT images revealed anasarca and lymphadenopathy in all 20 patients. The iMCD-TAFRO group showed significantly higher frequencies of ascites (100% vs. 37.5%, P = 0.004), gallbladder wall edema (75.0% vs. 12.5%, P = 0.020), periportal collar (91.7% vs. 25.0%, P = 0.004), and anterior mediastinal lesions (non-mass-forming infiltrative lesions) (66.7% vs. 12.5%, P = 0.028). Para-aortic edema tended to be more frequent in patients with the iMCD-TAFRO group (83.3% vs. 37.5%, P = 0.062), while the absence of anterior mediastinal lesions tended to be more frequent in the iMCD-non-TAFRO group (16.7% vs. 62.5%, P = 0.062). These CT findings may have clinical implications for improving the accuracy and speed of iMCD diagnosis and differentiating iMCD-TAFRO from other subtypes.

OBJECTIVES: This study aimed to compare the clinical outcomes of robot-assisted partial nephrectomy (RAPN) and image-guided percutaneous cryoablation (IG-PCA) for clinical T1 renal cell carcinoma. MATERIALS AND METHODS: We conducted a retrospective analysis of 679 patients with clinical T1 renal cell carcinoma treated with RAPN or IG-PCA between 2012 and 2021. Propensity scores were calculated via logistic analysis to adjust for imbalances in baseline characteristics. We compared oncological and functional outcomes between the 2 treatment groups. RESULTS: Following the matching process, 108 patients were included in each group. No patient in the RAPN group developed local recurrence. In the IG-PCA group, three patients experienced local tumor progression. The patients underwent salvage thermal ablations by the secondary technique; 2 underwent IG-PCA and 1 underwent microwave ablation, resulting in a local control rate of 100%. The Kaplan-Meier analysis showed no statistically significant differences between the groups in terms of 5-year recurrence-free survival, metastasis-free survival, and overall survival (log-rank test; P = 0.11, P = 0.64, and P = 0.17, respectively). No significant differences were observed in the 2 treatments in major and overall complication rates (P = 0.75 and P = 0.82, respectively). Both groups showed similar rates of less than 10% estimated glomerular filtration rate decline at 12 months post-treatment and 5-year renal function preservation rates (P = 0.88 and P = 0.38, respectively). CONCLUSIONS: IG-PCA demonstrated oncological outcomes comparable to those of RAPN. RAPN addressed the disadvantages of conventional procedures and allowed for safety outcomes comparable to IG-PCA.

BACKGROUND: Lung cancer with interstitial pneumonia is known to be a refractory disease. We explored whether systemic inflammatory response markers are associated with outcomes in these patients. METHODS: The participants of this multicenter retrospective study, consisting of 17 medical institutions, were treatment-naïve patients with lung cancer combined with interstitial pneumonia who underwent surgical resection between 2012 and 2017. We reviewed clinicopathologic characteristics, including systemic inflammatory response markers, and examined the relationship between these characteristics and postoperative survival. RESULTS: According to the inclusion criteria, the final cohort consisted of 181 patients. Among preoperative systemic inflammatory response markers, the C-reactive protein-to-albumin ratio was an independent prognostic factor in multivariable analysis (hazard ratio, 1.71; P = .018). We examined whether the C-reactive protein-to-albumin ratio could be a determining factor in selecting surgical procedures (wedge resection or segmentectomy/lobectomy) preoperatively for patients with early-stage lung cancer. Although not statistically significant, there is a trend that the C-reactive protein-to-albumin ratio can be a possible determining factor in selecting surgical procedures. CONCLUSIONS: Our results indicate that the C-reactive protein-to-albumin ratio is an independent prognostic factor for overall survival in treatment-naïve patients with lung cancer combined with interstitial pneumonia.

Abstract

Purpose

This study retrospectively evaluated the feasibility and safety of implanting a newly developed central venous access port (CV-port) that allows catheter insertion into a vein without the use of a peel-away sheath, with a focus on its potential to minimize risks associated with conventional implantation methods.

Materials and methods

All procedures were performed using a new device (P-U CelSite Port™ MS; Toray Medical, Tokyo, Japan) under ultrasound guidance. The primary endpoint was the implantation success rate. The secondary endpoints were the safety and risk factors for infection in the early postprocedural period (< 30 days).

Results

We assessed 523 CV-port implantations performed in a cumulative total of 523 patients (240 men and 283 women; mean age, 61.6 ± 13.1 years; range, 18–85 years). All implantations were successfully performed using an inner guide tube and over-the-wire technique through 522 internal jugular veins and one subclavian vein. The mean procedural time was 33.2 ± 10.9 min (range 15–112 min). Air embolism, rupture/perforation of the superior vena cava, or hemothorax did not occur during catheter insertion. Eleven (2.1%) intraprocedural complications occurred, including Grade I arrhythmia (n = 8) and subcutaneous bleeding (n = 1), Grade II arrhythmia (n = 1), and Grade IIIa pneumothorax (n = 1). Furthermore, 496 patients were followed up for ≥ 30 days. Six early postprocedural complications were encountered (1.1%), including Grade IIIa infection (n = 4), catheter occlusion (n = 1), and skin necrosis due to subcutaneous leakage of trabectedin (n = 1). These six CV-ports were withdrawn, and no significant risk factors for infection in the early postprocedural period were identified.

Conclusion

The implantation of this CV-port device demonstrated comparable success and complication rates to conventional devices, with the added potential benefit of eliminating complications associated with the use of a peel-away sheath.

PURPOSE: This study aimed to assess the outcomes of percutaneous cryoablation (PCA) for renal cell carcinomas (RCCs) contacting critical organs without intervening fat tissue. MATERIAL AND METHODS: Twenty-three patients with 24 RCCs (mean size, 28.8 mm) contacting critical organs on preprocedural images were included. The organ displacement techniques, technical success, efficacy, and adverse events per Clavien-Dindo classification were retrospectively reviewed. RESULTS: The organs contacting the RCCs included the colon (n = 16), pancreas (n = 3), duodenum (n = 3), small intestine (n = 1), and stomach (n = 1). In all procedures, hydrodissection was conducted, and probe traction was additionally utilized in one to displace organs. Two procedures were terminated with an insufficient ice-ball margin (<6 mm) due to recurring proximity of the colon or thermal sink effect by renal hilar vessels, yielding a technical success rate of 91.6% (22/24). No severe adverse events were noted. All patients were alive without any metastases during a median follow-up of 34.4 months. The primary and secondary technical efficacy rates were 91.6% (22/24) and 95.8% (23/24) of tumors, respectively. CONCLUSION: PCA can be a valid option for RCCs contacting critical organs with a good safety profile and sufficient technical efficacy.

This study aimed to evaluate the potential reduction in contrast medium utilization using photon-counting detector computed tomography (PCD-CT). One PCD-CT scan (CT1) and three conventional (non-PCD-CT) CT scans (CT2-CT4) were performed using a multi-energy CT phantom that contained eight rods with different iodine concentrations (0.2, 0.5, 1, 2, 5, 10, 15, and 20 mg/ml). The CT values of the seven groups (CT1 for 40, 50, 60, and 70 keV; and CT2-4) were measured. Noise and contrast-to-noise ratio (CNR) were assessed for the eight rods at various iodine concentrations. CT2 and CT1 (40 keV) respectively required 20 mg/ml and 5 mg/ml of iodine, indicating that a comparable contrast effect could be obtained with approximately one-fourth of the contrast medium amount. The standard deviation values increased at lower energy levels irrespective of the iodine concentration. The CNR exhibited a decreasing trend with lower iodine concentrations, while it remained relatively stable across all iodine levels (40-70 keV). This study demonstrated that virtual monochromatic 40 keV images offer a similar contrast effect with a reduced contrast medium amount when compared to conventional CT systems at 120 kV.

PURPOSE: Radiation pneumonitis (RP) is an obstacle for patients after surgery following induction chemoradiotherapy for locally advanced non-small cell lung cancer (LA-NSCLC). We performed a comparative analysis of the association between clinicopathological factors, including the neutrophil-to-lymphocyte ratio (NLR) and prognosis, in LA-NSCLC patients with or without RP during induction chemoradiotherapy followed by surgery. METHODS: The subjects of this analysis were 168 patients undergoing trimodality therapy for LA-NSCLC between January, 1999 and May, 2019. Patients were divided into two groups: the RP group (n = 41) and the non-RP group (n = 127). We compared the clinicopathological factors including the NLR between the groups and analyzed the association between the NLR and prognosis. RESULTS: The RP group had more patients with tumors located in the lower lobe, more bilobar resections, shorter operative times, no implementation of postoperative adjuvant chemotherapy, and a higher postoperative NLR than the non-RP group. There were no significant differences in serious postoperative complications and the prognosis. Patients with a low postoperative NLR had a significantly better prognosis in the non-RP group, and a trend toward a better prognosis even in the RP group. CONCLUSION: Postoperative NLR may be a useful prognostic factor, even for patients who suffer RP after trimodality therapy for LA-NSCLC.

PURPOSE: To retrospectively evaluate the depiction rate of feeding arteries in biopsy-proven clear cell renal cell carcinoma (CCRCC) on four-dimensional computed tomography angiography (4D-CTA) images. MATERIALS AND METHODS: This study included 22 patients with 22 CCRCC and 30 feeding arteries treated with transcatheter renal artery embolization. The depiction rate of the feeding arteries on preprocedural 4D-CTA was evaluated. Images were acquired by 320-row multi-detector computed tomography (CT) 15‒36 s after starting to inject a contrast agent (600 mg/kg iodine) intravenously into patients at 2.1 s intervals (11 phases). Two board-certified radiologists retrospectively assessed the feeder depiction rate in all 11 phases with reference to the procedural images as the gold standard. Discrepancies were resolved by consultation with a third radiologist. RESULTS: Among the feeders, 11 (36.7%) were segmental or lobar, and 19 (63.3%) were interlobar or arcuate arteries. The feeder depiction rate was the highest (25 [83.3%] of 30) in the 5th phase (delay, 23.4 s) where the gap in contrast enhancement between the renal artery and cortex was the largest. This was followed by the 6th (23 [76.7%] of 30), 4th (22 [73.3%] of 30]), and 7th (21 [70.0%] of 30) phases. The overall rate of depicting feeding arteries in the 11 phases of 4D-CTA was 28 (93.3%) of 30. CONCLUSIONS: The depiction rate of CCRCC feeding arteries including lobar or smaller artery branches by 4D-CTA was favorable. The feeding arteries were optimally visualized during the phase with the largest contrast gap between the renal artery and cortex.

This retrospective study investigated whether necrotic lesions detected on a computed tomography (CT) scan are more regressive than non-necrotic lesions after methotrexate withdrawal in patients pathologically diagnosed with methotrexate-associated lymphoproliferative disorders (MTX-LPD). In total, 89 lesions extracted from 24 patients on CT scans were included in the analysis. All patients had been evaluated for the presence of necrosis within lesions via CT scan upon first suspicion of MTX-LPD (baseline CT scan). The percentage lesion size reduction between the baseline and initial follow-up CT scan was calculated. The association between necrosis within lesions and size changes was estimated via linear regression analyses using both crude and adjusted models. Necrosis was significantly more common in extranodal lesions (27 out of 30 lesions, 90%) than in nodal lesions (9 out of 59 lesions, 15%, p<0.001). In the crude model, the regression of necrotic lesions was 58.5% greater than that of non-necrotic lesions; the difference was statistically significant (p<0.001). Additionally, the longest diameter of necrotic lesions at the baseline CT scan was significantly greater than that of non-necrotic lesions (p<0.001). Based on the adjusted model, necrotic lesions showed 49.3% greater regression than non-necrotic lesions (p=0.017). Necrosis detected on a CT scan was found to be an independent predictor of regression after MTX withdrawal in patients with MTX-LPD.

Abstract

Purpose

To retrospectively assess the time course of complications after image-guided small renal mass biopsy using initial follow-up imaging.

Materials and methods

A total of 190 masses (mean, 2.1 ± 0.70 cm; range, 0.6–3.8 cm) were assessed using initial computed tomography (43 non-enhanced and 141 enhanced) or magnetic resonance imaging (five non-enhanced and one enhanced) after biopsy. Initial follow-up imaging was classified into two groups (i.e., with or without hematoma) and various factors were compared.

Results

The masses were histologically diagnosed in all patients except one. Post-procedural complications included 129 Grade I hematomas, 1 Grade I hemothorax, 9 Grade II hematomas, and 1 Grade IIIa pneumothorax. Residual 28 Grade I and 6 Grade II hematomas and 8 new complications (6 small hematomas, 1 pseudoaneurysm, and 1 arteriovenous fistula) were observed on the initial follow-up imaging obtained at a median of 21 days (3–90 days) after the biopsy. On the initial follow-up imaging, the groups with and without hematoma differed significantly in the following factors: age (P = 0.04), size (P = 0.02), guided images (P < 0.01), hematoma at the end of the procedure (P < 0.01), and days after biopsy (P < 0.01). Although three masses exhibited > 25% shrinkage, no significant change was observed in mass diameter on initial follow-up imaging (mean, 2.1 ± 0.71 cm; P = 0.90).

Conclusion

Initial follow-up imaging after a biopsy revealed improvements in most of the complications, a few new complications, and an unchanged mass diameter.

PURPOSE: This single-center, single-arm, prospective, open-label study was conducted to evaluate the optimal number of cores (single or multiple) in renal tumor biopsy. MATERIALS AND METHODS: Forty-four biopsies of 44 tumors (mean diameter, 2.7 ± 1.0 cm; range, 1.6-5.0 cm) were included. Biopsy was performed under ultrasound or computed tomography fluoroscopy guidance using an 18-gauge cutting needle and the co-axial method. Two or more specimens were obtained, which were divided into first and subsequent specimens. "First specimen" and "all specimens" were histologically evaluated (i.e., appropriateness of specimen, histological diagnosis, subtype, and Fuhrman grade of renal cell carcinoma [RCC]) blindly and independently by two board-certified pathologists. RESULTS: Multiple specimens were successfully and safely obtained in all the biopsies. All tumors were histologically diagnosed; 40 malignancies included 39 RCCs and 1 solitary fibrous tumor, and 4 benign lesions included 2 angiomyolipomas, 1 oncocytoma, and 1 capillary hemangioma. In all RCCs, the subtype could be determined (32 clear cell RCCs, 4 chromophobe RCCs, and 3 papillary RCCs), and the Furman grade was determined in 38 RCCs. When only the first specimen was evaluated, 22.7% of the specimens were inappropriate for diagnosis, and 34 (77.3%) were histologically diagnosed. The diagnostic yield was significantly lower than that of all specimens (P = 0.0044). Univariate analysis revealed that smaller lesions were a significant predictor of diagnostic failure (P = 0.020). CONCLUSION: Biopsy with multiple cores significantly improved diagnostic yield. Thus, operators should obtain multiple cores during renal tumor biopsy.

Abstract

Background

Surgical resection of esophageal cancer is frequently performed to achieve a complete cure. However, the postoperative recurrence rate is 36.8–42.5%, leading to poor prognosis. Radiation therapy has been used to treat recurrences; solitary recurrence has been proposed as a prognostic factor for radiation therapy, though its significance is unclear. ¹⁸F-fluorodeoxyglucose positron emission tomography is a highly accurate diagnostic modality for esophageal cancer. This retrospective study aimed to analyze the outcomes of solitary postoperative recurrences of esophageal squamous cell carcinoma diagnosed with ¹⁸F-fluorodeoxyglucose positron emission tomography and treated with definitive radiation therapy.

Methods

We examined 27 patients who underwent definitive radiation therapy for single or multiple postoperative recurrences of esophageal squamous cell carcinoma between May 2015 and April 2021. ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography was performed within 3 months before the commencement of radiation therapy. Kaplan–Meier, univariate, and multivariate analyses were performed to examine the overall survival and identify potential prognostic factors.

Results

The 1-, 2-, and 3-year overall survival rates were 85.2%, 62.6%, and 47.3%, respectively, and solitary recurrence was the only significant factor associated with overall survival (P = 0.003). The 1-, 2-, and 3-year overall survival rates in patients with solitary recurrence were 91.7%, 80.2%, and 80.2%, respectively, and in patients with multiple recurrences they were 80.0%, 50.3%, and 25.1%, respectively. Multivariate analysis also showed solitary recurrence as a significant factor for overall survival.

Conclusions

When diagnosed with ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography, solitary recurrence appears to have a more favorable prognosis than multiple recurrences.

Abstract

Purpose

To retrospectively evaluate cryoablation combined with prior transcatheter arterial embolization (TAE) for renal cell carcinoma (RCC) in non-dialysis patients with stage 4 or 5 chronic kidney disease (CKD).

Materials and methods

Patients with stage 4 or 5 CKD undergoing TAE and cryoablation for RCC between May 2012 and October 2021 were included. TAE was selectively performed using iodized oil with absolute ethanol or gelatin sponge 1–14 days before cryoablation. Local efficacy, safety, and changes in renal function were evaluated.

Results

Nine patients (seven men and two women; median age, 64 years; range 52–88 years) with nine RCCs (mean diameter, 3.0 ± 1.0 cm; range 1.7–4.7 cm) were included. The mean pre-treatment estimated glomerular filtration rate (eGFR) was 24.2 ± 5.6 ml/min/1.73 m² (range 10.4–29.2 ml/min/1.73 m²). The mean amount of contrast medium used in TAE was 58 ± 29 ml (range 40–128 ml). Except in one patient (grade 3 pyelonephritis), no grade ≥ 3 complications occurred. During the follow-up period (median, 18 months; range 7–54 months), no local tumor progression occurred. In two patients with pre-treatment eGFR of < 20 ml/min/1.73 m², hemodialysis was initiated at 3 and 19 months after cryoablation. At their last follow-up, the remaining seven patients showed a decrease of 6.2 ± 5.3 ml/min/1.73 m² (range 0.7–17.2 ml/min/1.73 m²) in their eGFR.

Conclusion

Cryoablation combined with TAE for RCC in non-dialysis patients with stage 4 or 5 CKD was effective and safe, with an acceptable impact on renal function.

We report a rare case of idiopathic spinal cord herniation (ISCH) with a history of cerebrospinal fluid (CSF) leakage. ISCH is a protrusion of the spinal cord through a dural defect. Thin constructive interference in steady-state (CISS) images clearly demonstrated the herniated cord in the present case. The myelopathy worsened and the patient underwent surgery for reduction of herniated spinal cord; the dural defect was filled by placing collagen matrix graft (DuraGen®) between the inner and outer dural layers. The patient's symptoms have improved without relapse for 8 months since surgery. This method may be a good surgical option for cases of spinal cord herniation.

Abstract

Purpose

To retrospectively assess the feasibility, safety, renal function, technique efficacy rate, and survival of patients with clinical T3a renal cell carcinoma (RCC).

Materials and methods

Sixteen cryoablation sessions were performed in 14 patients (10 men; mean age, 69.8 ± 10.5 years; range, 49–90 years) with 14 clear cell T3a RCCs (mean, 3.3 ± 0.9 cm; range, 1.9–5.2 cm). One patient was on dialysis. Transcatheter arterial embolization was performed before cryoablation in 15 sessions. The primary endpoint was the technique efficacy rate. The secondary endpoints included feasibility, safety, renal function, and survival.

Results

Cryoablation was technically successful in all RCC cases. In two RCCs, cryoablation was performed twice because of local tumor progression. No major adverse events were observed. All patients were alive without metastases, with a median follow-up of 45 months (6−93 months). Complete response was achieved by cryoablation in 11 RCCs (78.6%). The primary and secondary technique efficacy rates were 77.1% and 84.4% at 1 year, 57.9% and 73.9% at 3 years, and 57.9% and 73.9% at 5 years, respectively. One patient underwent dialysis given a total contralateral nephrectomy due to another RCC 1 month after initial cryoablation and a total ipsilateral nephrectomy 46 months after initial cryoablation due to local progression. Except for two dialysis patients, of the 12 patients with a median follow-up of 41 months (6–93 months), none were on dialysis.

Conclusion

Cryoablation was safe and effective in T3a RCC, which mainly involved the renal venous branches and may represent an alternative treatment for inoperable patients.

Abstract

Purpose

This review aimed to summarize the treatment outcomes of percutaneous radiofrequency ablation (RFA) and microwave ablation (MWA) for metastatic liver tumors based on the findings of published studies over the last decade.

Materials and methods

Literature describing the survival outcomes of ablation therapy for liver metastases was explored using the PubMed database on April 26, 2022, and articles published in 2012 or later were selected. The included studies met the following criteria: (i) English literature, (ii) original clinical studies, and (iii) literature describing overall survival (OS) of thermal ablation for metastatic liver tumors. All case reports and cohort studies with fewer than 20 patients and those that evaluated ablation for palliative purposes were excluded.

Results

RFA was the most commonly used method for ablation, while MWA was used in several recent studies. RFA and MWA for liver metastases from various primary tumors have been reported; however, majority of the studies focused on colorectal cancer. The local control rate by RFA and MWA varied widely among the studies, ranging approximately 50–90%. Five-year survival rates of 20–60% have been reported following ablation for colorectal liver metastases by a number of studies, and several reports of 10-year survival rates were also noted.

Conclusion

Comparative studies of local therapies for colorectal liver metastases demonstrated that RFA provides comparable survival outcomes to surgical metastasectomy and stereotactic body radiation therapy.

Abstract

Purpose

To retrospectively evaluate and correlate the contrast-enhanced computed tomography (CECT) and non-enhanced magnetic resonance imaging (MRI) during the early period following renal cryoablation.

Materials and methods

Both dynamic CECT and non-enhanced MRI were performed within 4 days following cryoablation in 34 renal tumors in 33 patients. The renal volumes of the unenhanced regions on dynamic CECT (nephrogenic phase, 4 mm thickness) and the regions with signal intensity changes on non-enhanced MRI (fat-suppressed T2-weighted image, 4 mm thickness) were evaluated. Fusion images of the axial, coronal, and sagittal sections of CECT and MRI images were created from the maximum cross-section of the renal tumor, and the match score of each image was visually evaluated on a 5-point scale.

Results

The mean renal volume of the unenhanced regions on CECT and those with signal intensity changes on non-enhanced MRI following cryoablation were 29.5 ± 19.9 cm³ (range, 4.3–97.4 cm³) and 30.7 ± 19.8 cm³ (range, 6.7–94.0 cm³), respectively; the difference between them was –1.17 cm³ (95% confidence interval [CI] –2.74, 0.40, P = 0.139). The Pearson’s product-moment correlation coefficient (r = 0.975; 95% CI, 0.951, 0.988; P < 0.0001) showed a strong correlation between the volumes. The average match score between CECT and non-enhanced MRI was as high as 4.5 ± 0.5 points (radiologist 1, 4.3 ± 0.5; radiologist 2, 4.7 ± 0.5). Local tumor control rate was 94.1% (32/34 tumors) and recurrence-free survival rate was 82.0% (95% CI: 64.2%, 91.5%) at 5 years.

Conclusions

The region with signal intensity changes on non-enhanced MRI was strongly correlated with the unenhanced region on CECT during the early period following renal cryoablation.

Abstract

The aim of this review was to summarize the latest evidence on image-guided thermal ablation therapies for lung metastases. PubMed was used to search for relevant articles that reported the oncological outcomes of thermal ablation for metastatic lung tumors, and those published in 2010 or later were selected for review. Ablative therapies were applied for lung metastases from various types of primary tumors, but most commonly colorectal ones. Radiofrequency ablation (RFA) was the most evaluated technique, followed by microwave ablation (MWA). The local control rates of ablative therapies were generally favorable, approximately 80–90% in many studies. Representative studies demonstrated promising overall survival rates of approximately 50% or higher 5 years after ablation for lung metastases from colorectal cancer or mixed types of primary tumors. Nevertheless, the survival outcomes varied depending on the type of primary tumor and background factors of patients such as other metastases and comorbidities. Several studies had aimed to compare the outcomes of various ablative therapies such as RFA, MWA, and cryoablation; however, conclusive data are not yet available to determine the most appropriate ablation modality for lung metastases. Further data accumulation is needed, especially for long-term outcomes and comparisons with other therapies.

PURPOSE: The purpose of this study was to retrospectively determine the incidence of early enlarging cavitation after percutaneous radiofrequency ablation (RFA) of lung tumor and identify risk factors associated with their occurrence. PATIENTS AND METHODS: A total of 245 patients (140 men, 105 women; mean age, 62.7 ± 11.8 [SD] years; age range: 31-87 years) with 605 lung tumors who were treated using 401 RFA sessions from April 2010 to March 2020 were included. Of which, 31 patients with 38 early enlarging cavitation and control group (151 patients with 228 tumors) were analyzed. Early enlarging cavitation was defined as cavities with an enlarged size (>3 cm) occurring on ablated lesions within seven days after RFA. Incidence of cavitation, risk and post-procedural factors of occurrence, major adverse events (AEs) that occurred in RFA sessions with cavitation, and course of cavitation were evaluated. AEs were classified using the CIRSE classification system for complications. RESULTS: Thirty-eight cavities (6.3%, 38/605 tumors) in 31 patients occurred in an average of 3.1 ± 1.7 days (range, 1-7 days) after 32 RFA sessions. Distance from pleura ≥ 20 mm, contact with vessel ≥ 3 mm, multitined expandable electrode ≥ 3 cm, and bronchus ≥ 2 mm encompassed in the ablation zone were independent risk factors of occurrence. Fever ≥ 38.5 °C, white blood cell count ≥ 10,000/μl one day after RFA, and steroid therapy were independent post-procedural factors of occurrence. Twenty-four Grade 3 and two Grade 6 AEs occurred. Twenty-nine cavities disappeared within a mean duration of 111.9 ± 64.9 (SD) days (range: 44-274 days) and four remained with a mean follow-up of 279.2 ± 174 (SD) days; five patients were lost to follow-up. CONCLUSIONS: Early enlarging cavitation occurs in 6.3% of lung tumors treated with RFA and are associated with 26 major AEs in 32 sessions. Aforementioned procedural factors and post-procedural inflammation were significant risk factors of occurrence.

Abstract

We analyzed the local control (LC) of cervical squamous cell carcinoma treated by computed tomography (CT)-based image-guided brachytherapy (IGBT) using central shielding (CS). We also examined the value of tumor diameter before brachytherapy (BT) as a factor of LC. In total, 97 patients were analyzed between April 2016 and March 2020. Whole-pelvic (WP) radiotherapy (RT) with CS was performed, and the total pelvic sidewall dose was 50 or 50.4 Gy; IGBT was delivered in 3–4 fractions. The total dose was calculated as the biologically equivalent dose in 2 Gy fractions, and distribution was modified manually by graphical optimization. The median follow-up period was 31.8 months (6.3–63.2 months). The 1- and 2-year LC rates were 89% and 87%, respectively. The hazard ratio was 10.11 (95% confidence interval: 1.48–68.99) for local recurrence in those with a horizontal tumor diameter ≥ 4 cm compared to those with &lt; 4 cm before BT. In CT-based IGBT for squamous cell carcinoma, favorable LC can be obtained in patients with a tumor diameter &lt; 4 cm before BT. However, if the tumor diameter is ≥ 4 cm, different treatment strategies such as employing interstitial-BT for dose escalation may be necessary.

In this paper, we focused on the medical procedure to insert needles under computer tomography (CT) guidance as a target for the robotization of medical surgery, which is one of Interventional Radiology (IR). IR is a general term for treatments that use devices to visualize patients’ bodies. During surgery, our developed robot, known as Zerobot, specializes in inserting a needle into the patient under CT guidance. Its surgery is less invasive and more effective in treating small cancer tumors because the temperature of the inserted needle tip is controlled. Zerobot was originally designed to be remotely controlled by doctors, and first-in-human feasibility trials in 2018 confirmed its surgical capability. We are currently focusing on the automatic insertion function to reduce the workload of doctors. In an animal experiment, Zerobot was unable to insert the needle into the animal during IR surgery if the needle was bent. As a result, the goal of this research is to have the robot function automatically so that the needle does not bend during surgery. We propose a method for estimating the form of the needle using a force sensor. There are three different types of needle forms. Next, the proposed method distinguishes between these needle forms by measuring the difference in force sensor data when the needle root is moved slightly. In addition, we conducted tests to confirm the efficacy of the proposed method.

Herein, we report two cases of duodenal ulcers that developed after transcatheter procedures for the treatment of unruptured artery aneurysms. Both patients recovered after the administration of nothing by mouth, intravenous fluids, and proton-pump inhibitors. Notably, the duodenal ulcer was unchanged in one patient six days after endovascular treatment and improved in the other patient 13 days after angiography. These cases suggest that conservative treatment is acceptable in patients with duodenal ischemia that develops as an adverse effect of endovascular procedures. The usefulness of esophagogastroduodenoscopy in such patients has also been highlighted.

Language：English Publishing type：Research paper (scientific journal) Publisher：SAGE Publications

Background

Meningiomas are occasionally fed by pial blood supply (PBS). It is postulated that peritumoral flow void (PTFV), peritumoral brain edema (PTBE), and absence of an arachnoid plane (AP) are useful parameters for evaluating PBS.

Purpose

To determine whether conventional magnetic resonance imaging (MRI) using a multiparametric scoring system (MSS) is a useful way to predict PBS.

Material and Methods

Forty-six patients were included and divided: PBS and non-PBS groups. Differences between the groups in six parameters of MR imaging were analyzed: tumor size, tumor location, PTBE grade, AP grade, PTFV, and MIB1 labeling index (MIB1-LI) grade. Cutoff values were determined using receiver operating characteristic (ROC) curve analysis for the differentiation of both groups based on statistically significant parameters. All cases were scored as 1 (PBS) or 0 (non-PBS) for each parameter according to set thresholds. Individual scores were totaled for each case, yielding a combined score for each case to obtain a cutoff value using ROC curve analysis for the MSS.

Results

Peritumoral brain edema grade, AP grade, PTFV, and MIB-LI grade were statistically associated with PBS. Receiver operating characteristic curve analyses showed that PTBE grade 3 or 4, AP grade 3 or 4, and PTFV positivity had the highest accuracy of 69%, 64%, and 68%, respectively. Regarding the MSS, a cutoff value of 2 had the highest accuracy of 71%; PBS diagnosis was indicated by at least two of the three parameters, namely, PTBE grade, AP grade, and PTFV.

Conclusion

The MSS is a useful way to predict PBS in intracranial meningiomas on MRI.

To evaluate the volume and heat-sink effects of microwave ablation (MWA) in the ablation zone of the normal swine lung. MWA at 100 W was performed for 1, 2, and 3 min in 7, 5, and 5 lung zones, respectively. We assessed the histopathology in the ablation zones and other outcome measures: namely, length of the longest long and short axes, sphericity, ellipsoid area, and ellipsoid volume. The mean long- and short-axis diameters were 22.0 and 14.1 mm in the 1-min ablation zone, 27.6 and 20.2 mm in the 2-min ablation zone; and 29.2 and 21.2 mm in the 3-min ablation zone, respectively. All measures, except sphericity, were significantly less with 1-min ablation than with either 2- or 3-min ablation. There were no significant differences between the 2- and 3-min ablation zones, but all measures except sphericity were larger with 3-min ablation. Although there were no blood vessels that resulted in a heat-sink effect within the ablation zones, the presence of bronchi nearby in 5 lung ablation zones resulted in reduced ablation size. In high-power, short-duration MWA, the lung ablation volume was affected by ablation time. Some ablations showed that a heat-sink effect by a neighboring bronchus might occur.

AIM: To investigate whether muscle and adipose mass are associated with radiation pneumonitis (RP) in patients with non-small cell lung cancer undergoing preoperative concurrent chemoradiotherapy. PATIENTS AND METHODS: We calculated body mass index and determined skeletal muscle, psoas muscle, visceral adipose tissue (VAI), and subcutaneous adipose tissue indices, and visceral-to-subcutaneous adipose tissue area ratio for patients using computed tomography. We examined their relationship with grade 2 or more RP. RESULTS: Among 94 patients, 28 experienced grade 2 or more RP. On multivariate analysis, only VAI was associated with grade 2 or more RP (all p=0.026). The 6-month incidence rates of grade 2 or more RP were 21.4% and 36.8% in patients with VAI <39 and ≥39 cm 2 /m 2 , respectively. CONCLUSION: High visceral adipose mass is associated with grade 2 or more RP in patients undergoing preoperative concurrent chemoradiotherapy. Measuring visceral adipose mass may help to predict RP occurrence. Further studies are needed to validate our findings.

Development of a Robot (Zerobot^®) for Needle Insertion during CT Fluoroscopy-guided Intervention Reviewed

Computed tomography (CT) fluoroscopy-guided interventions such as ablation and biopsy are performed by inserting a specific needle into the lesion under CT fluoroscopy-guidance While those have various advantages including less invasive procedure, short procedure time, and low cost, a major concern to physicians is intraprocedural radiation exposure. In order to address this concern, we hypothesized that a remotely controllable robot could free physicians from radiation exposure. Since 2012, therefore, we have developed such a robot (Zerobot^®), the tasks of which are to hold, target, and insert a needle under CT-guidance by a physician's remotely manipulating a controller. The robot is floor-mounted and specially designed for a sliding-gantry CT scanner for CT-guided interventions. Phantom experiments showed that robotic needle insertion was equivalent in accuracy without exposing the physician to radiation, in comparison to manual insertion. Animal experiments showed that it was feasible, safe, and accurate in an in vivo procedure. In this article, we provide an overview of the robot, including future perspectives.

Dr. Takao Hiraki is a scientist carrying out interventional radiology research in the Department of Radiology at Okayama University Medical School, Japan. He has conducted animal and human clinical studies on interventional radiology for various conditions. For example, he clarified the hepatic hemodynamic changes caused by hepatic venous occlusion. He also developed new devices, such as hydrogel coils for the occlusion of the aneurismal sac after an endovascular stent-graft of an aortic aneurysm to prevent endoleakage and small intestinal submucosa-covered stents for transjugular intrahepatic portosystemic shunts. Further, he performed a number of studies on the radiofrequency ablation of lung cancer, mediastinal lymph node metastasis, and computed tomography-fluoroscopy-guided lung biopsies. He intends to continue to dedicate his academic career to expand the role of interventional radiology in clinical medicine.

Language：English

As one of the key pillars of work style reform for physicians, task shifting and sharing from radiologists to radiological technologists has been considered. In May 2021, the Radiological Technologists Act was amended, allowing for the expansion of several duties. Alongside these legal and regulatory changes, a notice from Ministry of Health, Labour and Welfare was issued, highlighting tasks to be particularly promoted under the current system prior to the amendment of the Radiological Technologists Act. These amendments authorize radiological technologists to perform advanced and specialized tasks, such as securing venous access for contrast agent administration, which require significantly higher skill levels than their traditional roles. However, the amended legislation did not include specific guidelines, rules, or considerations for the practical implementation of these new duties in daily medical practice, especially from the perspectives of patient safety and quality of care. To address this, the Japan Radiological Society, the Japanese College of Radiology, and the Japan Association of Radiological Technologists collaborated with other related societies to develop guidelines on five key topics:-Guidelines for Safe Conduct of CT/MRI Contrast-Enhanced Examinations: Considering the expanded scope of practice for radiological technologists. -Guidelines for Safe Conduct of Nuclear Medicine Examinations: Aligned with the expanded responsibilities of radiological technologists. -Guidelines for Clinical application of Image-Guided Radiation Therapy (IGRT). -Guidelines for Safe Conduct of Angiography and Interventional Radiology (IR): Adapted for the expanded roles of radiological technologists. -Guidelines for Reporting Findings of STAT Imaging: Addressing urgent conditions with potential impact on life prognosis.

Language：English

BACKGROUND: No direct cost comparison has been conducted between percutaneous cryoablation (PCA) and robot-assisted partial nephrectomy (RAPN) for clinical T1a renal cell carcinoma (RCC) in Japan. This study aimed to compare their costs. METHODS: We retrospectively analyzed data from 212 PCAs (including 155 with transcatheter arterial embolization) and 119 RAPN cases performed between December 2017 and May 2022. RESULTS: PCA patients were older with higher American Society of Anesthesiologists scores, Charlson Comorbidity Index, and history of previous RCC treatment, cardiovascular disease, and antithrombotic drug use than RAPN patients. PCA was associated with a significantly shorter procedure time and hospitalization duration with fewer major complications than those associated with RAPN. While PCA incurred a slightly lower total cost (1,123,000 vs. 1,155,000 yen), it had a significantly higher procedural cost (739,000 vs. 693,000 yen) and markedly worse total (- 93,000 vs. 249,000 yen) and procedural income-expenditure balance (- 189,000 vs. 231,000 yen) than those of RAPN. After statistical adjustment, PCA demonstrated significantly higher total (difference: 114,000 yen) and procedural costs (difference: 72,000 yen), alongside significantly worse total (difference: - 358,000 yen) and procedural income-expenditure balances (difference: - 439,000 yen). The incremental cost-effectiveness ratio was more favorable for PCA than for RAPN. CONCLUSION: For high- risk patients, PCA demonstrated a safer option with shorter hospitalization duration than those of RAPN. Although PCA was more cost-effective, its higher procedural cost and unfavorable income-expenditure balance require careful evaluation, especially for large tumors that require three or more needles.

The clinical imaging features of photon-counting detector (PCD) computed tomography (CT) are mainly known as dose reduction, improvement of spatial resolution, and reduction of artifacts compared to energy-integrating detector CT (EID-CT). The utility of cranial and spinal PCD-CT and PCD-CT angiography (CTA) has been previously reported. CTA is a widely used technique for noninvasive evaluation. Cranial CTA is important in brain tumors, especially glioblastoma; it evaluates whether the tumor is highly vascularized prior to an operation and helps in the diagnosis and assessment of bleeding risk. Spinal CTA has an important role in the estimation of feeders and drainers prior to selective angiography in the cases of spinal epidural arteriovenous fistulas and spinal tumors, especially in hemangioblastoma. So far, EID-CTA is commonly performed in an adjunctive role prior to selective angiography; PCD-CTA with high spatial resolution can be an alternative to selective angiography. In the cases of cerebral aneurysms, flow diverters are important tools for the treatment of intracranial aneurysms, and postoperative evaluation with cone beam CT with angiography using diluted contrast media is performed to evaluate stent adhesion and in-stent thrombosis. If CTA can replace selective angiography, it will be less invasive for the patient. In this review, we present representative cases with PCD-CT. We also show how well the cranial and spinal PCD-CTA approaches the accuracy of angiographic and intraoperative findings.

PURPOSE: To retrospectively investigate the safety and effectiveness of percutaneous radiofrequency (RF) ablation by analyzing results in patients with lung neoplasm accompanied by interstitial lung disease (ILD) on computed tomography (CT) in a multicenter study. MATERIALS AND METHODS: Patients with lung neoplasm accompanied by ILD who underwent RF ablation between April 2002 and October 2017 at 7 institutions were investigated. Technical success rate and local tumor progression (LTP) of ablated tumors were evaluated. Adverse events including acute exacerbation of ILD were also evaluated. Univariate analyses were performed to identify factors associated with acute exacerbation. RESULTS: Forty-nine patients with 64 lung neoplasms (mean diameter, 23 mm; range, 4-58 mm) treated in 66 sessions were included. Usual interstitial pneumonia (UIP) pattern on CT was identified in 23 patients (47%). All patients underwent successful RF ablation. Acute exacerbations were seen in 5 sessions (8%, 7% with UIP pattern and 8% without) in 5 patients, all occurring on or after 8 days (median, 12 days; range, 8-30 days). Three of those 5 patients died of acute exacerbation. Treatment resulted in mortality after 5% of sessions, representing 6% of patients. Pleural effusion and fever (temperature ≥ 38°C) after RF ablation were identified by univariate analysis (P = .001 and P = .02, respectively) as significant risk factors for acute exacerbation. The cumulative LTP rate was 43% at 1 year. CONCLUSIONS: RF ablation appears feasible for patients with lung neoplasm complicated by ILD. Acute exacerbation occurred in 8% of patients with symptoms occurring more than 8 days after ablation and was associated with a 45% mortality rate.

We report the case of a 38-year-old man with two von Hippel-Lindau disease-associated T1a renal cell carcinomas (RCCs) (<2 cm in diameter) which developed into a 2.5-cm solitary diaphragmatic metastatic tumor. After diagnosis using percutaneous biopsy, the diaphragmatic metastasis and two RCCs were treated by laparoscopic resection and percutaneous cryoablation, respectively. One year after treatment, the patient survived without local recurrence or distant metastasis. This report describes a rare case of RCC metastasis in VHL disease and its treatment.

A 50-year-old man with von Hippel–Lindau disease underwent cryoablation (CRA) for two adjacent renal cell carcinomas in the upper pole of his right kidney. Although computed tomography (CT) immediately after CRA revealed involvement of part of the liver parenchyma in the ice-ball, the treatment was completed without complications. Contrast-enhanced CT on day 2 post-CRA revealed a thrombus in the portal vein of segment 6 near the ablated liver parenchyma, prompting the initiation of oral anticoagulation. The patient was discharged on day 4 after CRA without any sequelae, and a follow-up contrast-enhanced CT done 6 weeks later demonstrated resolution of the portal vein thrombus.

We report a case of postoperative pseudoaneurysm, successfully treated with selective arterial embolization, using a steerable microcatheter and triaxial system via retrograde approach. A pseudoaneurysm was detected in the dorsal pancreatic artery, a severely narrow and steeply inverted branch of the superior mesenteric artery, making microcatheter insertion via the antegrade approach challenging. However, a steerable microcatheter was advanced beyond the orifice and the tip was reversed, changing the route to retrograde allowing for easy insertion of the microguidewire. Subsequently, a small microcatheter was advanced beyond the pseudoaneurysm into the dorsal pancreatic artery, and arterial embolization was successfully completed without complications.

PURPOSE OF REVIEW: To review the current status of kidney tumor ablation in patients with substantial kidney impairment. RECENT FINDINGS: Few reports of kidney tumor ablation in such patients have recently been published. The reported prevalence of patients with stage 4 or 5 chronic kidney disease (CKD) among patients undergoing ablation is 2.0%-10%. In patients with stage 4 or 5 CKD, local tumor control rates were 88%-100%. The effect of ablation on CKD stage is unclear, and the observed deteriorations in kidney function are consistent with both the effect of cryoablation and the natural course of advanced CKD. According to guidelines, active surveillance may be selected. The goals of treatment are complete tumor removal and maintenance of kidney function, both of which can be met by ablation. Given the limited treatment options, ablation may play a pivotal role in the management of patients with advanced CKD.

We report the rare case of an 80-year-old man with hepatocellular carcinoma that ruptured in the gallbladder, causing a cystic artery pseudoaneurysm and hemobilia. Emergency transarterial embolization (TAE) successfully controlled the bleeding without causing ischemic cholecystitis. Cone-beam computed tomography angiography was useful in identifying the bleeding branch of the selectively embolized cystic artery. Although the patient had poor liver function (Child-Pugh class C) before TAE, it remarkably improved after embolization due to the resolution of coagulopathy and obstructive jaundice caused by hemobilia. TAE was considered useful for this rare clinical condition.

Abstract

Introduction

Diffuse hemispheric glioma, H3 G34-mutant (DHGs), is a newly categorized tumor in pediatric-type diffuse high-grade gliomas, World Health Organization grade 4, with a poor prognosis. Although prognostic factors associated with genetic abnormalities have been reported, few reports have examined the clinical presentation of DHGs, especially from the viewpoint of imaging findings. In this study, we investigated the relationship between clinical factors, including imaging findings, and prognosis in patients with DHGs.

Methods

We searched Medline through the PubMed database using two search terms: “G34” and “glioma”, between 1 April 2012 and 1 July 2023. We retrieved articles that described imaging findings and overall survival (OS), and added one DHG case from our institution. We defined midline invasion (MI) as invasion to the contralateral cerebrum, brainstem, corpus callosum, thalamus, and basal ganglia on magnetic resonance imaging. The primary outcome was 12-month survival, estimated using Kaplan–Meier curves and logistic regression.

Results

A total of 96 patients were included in this study. The median age was 22 years, and the proportion of male patients was 48.4%. Lesions were most frequently located in the frontal lobe (52.6%). MI was positive in 39.6% of all patients. The median OS was 14.4 months. Univariate logistic regression analysis revealed that OS was significantly worse in the MI-positive group compared with the MI-negative group. Multivariate logistic regression analysis revealed that MI was an independent prognostic factor in DHGs.

Conclusions

In this study, MI-positive cases had a worse prognosis compared with MI-negative cases.

PURPOSE: To evaluate the detection rate of feeding arteries in renal cell carcinoma with automated feeder-detection software and determine the optimal imaging phase for accurate feeder detection with transarterial time-resolved computed tomography angiography. MATERIALS AND METHODS: The performance of automated feeder-detection software was retrospectively evaluated using transarterial renal time-resolved computed tomography angiography images of 15 renal cell carcinomas (mean size, 22.1 mm); the images were obtained via the renal artery using a hybrid angio-CT system with 320-row computed tomography, across nine phases with 0.5-s intervals over a contrast delay time of 1.0-5.0 s. Automated feeder-detection software was applied to each phase in all tumors (135 image series in total). The feeder-detection rate (i.e., sensitivity) in each phase was evaluated, and the number of false feeders demonstrated by the software was counted for each tumor. RESULTS: A total of 22 feeders were identified. The feeder-detection rate was the highest (95.5% [21/22]) at delay times of 1.5 s and 2.0 s and lower in later phases. At delay times of 1.0 s and 1.5 s, the software demonstrated no or only a few (≤ 3) false feeders in 93.3% (14/15) of the tumors. In later phases, however, many (≥ 4) false feeders were observed in > 50% of tumors. CONCLUSION: The automated feeder-detection software showed a favorable feeder-detection rate and may be useful in transarterial embolization for renal cell carcinoma. The optimal delay time to avoid the demonstration of false feeders and achieve a high detection accuracy was 1.5 s. LEVEL OF EVIDENCE IV: Case Series.

A 68-year-old woman was admitted to our hospital because of a rapid progression of renal dysfunction with positive myeloperoxidase antineutrophil cytoplasmic antibody and was diagnosed with rapidly progressive glomerulonephritis associated with microscopic polyangiitis (MPA). Severe right rectus sheath hematoma (RSH) bleeding from the inferior epigastric artery developed after starting hemodialysis, which required 4 transarterial embolizations due to recurrent bleeding. After additional treatment with methylprednisolone pulse therapy and rituximab, no rebleeding occurred. Although the giant hematoma reached the pelvis, it shrank spontaneously without any intervention. Nontraumatic RSH should therefore be considered when treating patients with multiple risk factors.

A 67-year-old man was referred to our hospital for the diagnosis and treatment of prostate cancer. Multidisciplinary discussion led to intensity-modulated radiotherapy preceded by hormone therapy. Before radiotherapy, a biodegradable hydrogel spacer (HS) was placed between the prostate and rectum to reduce radiation injury risk. Three weeks postplacement, pelvic magnetic resonance imaging revealed HS migration into the pelvic vein. Subsequent whole-body contrast-enhanced computed tomography (CECT) revealed HS migration into the pulmonary artery. The patient showed no symptoms or clinical signs. Radiotherapy was completed uneventfully. Complete absorption of the migrated HS was confirmed using CECT images 5 months postplacement.

We report the case details of a 65-year-old Japanese man with an omental abscess that was discovered 43 days after he underwent a laparoscopic proximal gastrectomy for gastric cancer. His chief complaint was mild abdominal pain that had persisted for several days. The abscess was diagnosed as a rare postoperative complication. We hesitated to perform a reoperation given the invasiveness of general anesthesia and surgery, plus the possibility of postoperative adhesions and because the patient's general condition was stable and he had only mild abdominal pain. Percutaneous drainage using a 10.2-F catheter was performed with the patient under conscious sedation and computed tomography-fluoroscopy guidance, with no complications. After the procedure, the size of the abscess cavity was remarkably reduced, and 23 days later the catheter was withdrawn.

Abstract

Recently, computed tomography with photon-counting detector (PCD-CT) has been developed to enable high-resolution imaging at a lower radiation dose. PCD-CT employs a photon-counting detector that can measure the number of incident X-ray photons and their energy. The newly released PCD-CT (NAEOTOM Alpha, Siemens Healthineers, Forchheim, Germany) has been in clinical use at our institution since December 2022. The PCD-CT offers several advantages over current state-of-the-art energy-integrating detector CT (EID-CT). The PCD-CT does not require septa to create a detector channel, while EID-CT does. Therefore, downsizing the anode to achieve higher resolution does not affect the dose efficiency of the PCD-CT. CT is an indispensable modality for evaluating ear ossicles. The ear ossicles and joints are clearly depicted by PCD-CT. In particular, the anterior and posterior legs of the stapes, which are sometimes unclear on conventional CT scans, can be clearly visualized. We present cases of congenital anomalies of the ossicular chain, ossicular chain dislocation, tympanosclerosis, and cholesteatoma in which PCD-CT was useful. This short article reports the usefulness of PCD-CT in the 3D visualization of the ear ossicles.

The most common sites of extrahepatic metastases from hepatocellular carcinoma (HCC) are the lungs, intra-abdominal lymph nodes, bones, and adrenal glands, in that order. Although systemic therapies are a common treatment for patients with extrahepatic metastases, local ablative therapies for the extrahepatic metastatic lesions can be performed in selected patients. In this article, the literature on image-guided thermal ablation for metastasis to each organ was reviewed to summarize the current evidence. Radiofrequency ablation was the most commonly evaluated technique, and microwave ablation, cryoablation, and percutaneous ethanol injection were also utilized. The local control rate of thermal ablation therapy was relatively favorable, at approximately 70–90% in various organs. The survival outcomes varied among the studies, and several studies reported that the absence of viable intrahepatic lesions was associated with improved survival rates. Since only retrospective data from relatively small studies has been available thus far, more robust studies with prospective designs and larger cohorts are desired to prove the usefulness of thermal ablation for extrahepatic metastases from HCC.

Percutaneous cryoablation of renal tumors is widely used because of its high efficacy and safety. This high safety can be attributed, at least in part, to the visibility of the ablated area as an "ice ball". This therapy has fewer complications (incidence, 0-7.2%) and is less invasive than surgery. Minor bleeding is inevitable in most kidney-related procedures, and indeed the most common complication of this therapy is bleeding (hematoma and hematuria). However, patients require treatment such as transfusion or transarterial embolization in only 0-4% of bleeding cases. Various other complications such as ureteral or collecting system injury, bowel injury, nerve injury, skin injury, infection, pneumothorax, and tract seeding also occur, but they are usually minor and asymptomatic. However, operators should know and avoid the various complications associated with this therapy. This study aimed to summarize the complications of percutaneous cryoablation for renal tumors and provide some techniques for achieving safe procedures.

Osteoid osteoma (OO) is a benign bone tumor that presents with nocturnal pain. Computed tomography (CT)- guided radiofrequency ablation (RFA) has been widely performed for OO, and major adverse events post-RFA are rare. We report a case of OO in the left navicular bone of a 15-year-old male. He underwent RFA for OO, and the pain improved temporarily. At the 1-month follow-up, the patient complained of left foot pain, and a CT examination revealed a fracture of the ablated navicular bone. Fractures are rare but must be taken into account after bone RFA.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, the number of this surgery tends to increase. However, doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. When doctors operate by remote control, there is possibility that parts of the robot collide with peripheral devices or a patient. Especially, if in the case of collision with the patient, it could become a serious incident. Accordingly, it is important to build a suitable path plan of the needle insertion before the surgery. Doctors, however, currently, do not have methods to grasp the possibility of the collision. Therefore, a simulation which detect collision with a patient in the advanced planning is proposed in this paper. The effectiveness of proposed simulation is confirmed.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, but doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. As a research topic, automated needle puncturing by the robot is focused on. However, currently the robot cannot obtain CT image in real time. So, the robot cannot obtain the form of needle based on CT image and cannot control state of needle accurately. On the other hands, we aim that the robot moves automatically for restraining a bend of needle. As the first step for this, the method to estimate a form of needle by using a force sensor information is proposed in this paper. If a form of the needle is displayed in user interface, it become easy for doctors to remove a bend of the needle during surgery with remote-controlled IR assistance robot. Additionally, we conducts the experiment to confirm effectiveness of proposed method.

Computed tomography (CT)-guided interventional procedures are performed by inserting a specific needle into a lesion under CT-guidance. Such procedures include cancer ablation, biopsy, and abscess drainage. The procedures are minimally invasive and thus their need is increasing in the super-aging society. However, major limitation is intraprocedural radiation exposure to the physicians, because they have to be close to CT gantry during CT scanning. In order to address this concern, I, together with robotic engineers, started to develop a robot (Zerobot®) at Okayama University in 2012. The robot for clinical study was completed at the end of 2015. The robot has six degrees of freedom to hold, position, orient, and insert a needle under CT-guidance. The robot may be remotely controlled by using an operation interface and thus, the physicians may be free from radiation exposure. In 2018, we have performed a first-in-human study for 10 cases of CT-guided biopsy using the robot in the kidney, lung, adrenal grand, mediastinum, and muscle, which resulted in success in all cases. We will start an investigator-initiated clinical study based on Good Clinical Practice in 2020, aiming at commercialization of the robot.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, but doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. We are currently developing an automated puncture system. Deviation of puncture point on body surface causes needle deflection during the automatic puncture. Because the needle deflection grows with the inserted depth, it makes the needle difficult to reach the target tumor. So as to solve them, the floating mechanism is developed to suppress needle deflection. Displacement sensor on floating mechanism can measure the movement of the floating part. In addition, the puncture reaction force can be measured by the force sensor on the robot. Algorithms to suppress the needle deflection using this information are proposed in this paper.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, the number of this surgery tends to increase. However, doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. When doctors operate by remote control, there is possibility that parts of the robot collide with peripheral devices or a patient. Especially, if in the case of collision with the patient, it could become a serious incident. Accordingly, it is important to build a suitable path plan of the needle insertion before the surgery. Doctors, however, currently, do not have methods to grasp the possibility of the collision. Therefore, a simulation which detect collision with a patient in the advanced planning is proposed in this paper. The effectiveness of proposed simulation is confirmed.

A remote-controlled robot for CT-guided needle insertion has been developed to prevent a doctor from radiation exposure. However, it is difficult for a doctor to recognize abnormal states of insertion when the doctor uses the robot because the doctor cannot obtain force sense information from the needle directly. Such an abnormal state occurs when a needle contacts with a bone. Therefore, we propose detecting abnormal states of insertion if force sensor value exceed a threshold and stopping the robot automatically. First, we conducted experiments to determine thresholds. We measured force values when a doctor feels the sign of plastic deformation in needles. In consideration of the stop time delay, thresholds were set by subtracting the rise values of force from the measured force values. Then, we verified that the robot can stop appropriately by the thresholds without occurring plastic deformation.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Since this surgical method is less invasive, but doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. As a research topic, automated needle puncturing by the robot is focused on. However, currently the robot cannot obtain CT image in real time. So, the robot cannot obtain the form of needle based on CT image and cannot control state of needle accurately. On the other hands, we aim that the robot moves automatically for restraining a bend of needle. As the first step for this, the method to estimate a form of needle by using a force sensor information is proposed in this paper. If a form of the needle is displayed in user interface, it become easy for doctors to remove a bend of the needle during surgery with remote-controlled IR assistance robot. Additionally, we conducts the experiment to confirm effectiveness of proposed method.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting attention. Doctors can perform IR percutaneously while observing the fluoroscopic image, such as CT and MRI images, of patients. Therefore, this surgical method is less invasive. However, doctors are exposed to strong radiation in the case under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. A registration function, which calculates offsets of coordinate systems, and a three dimensional display function, which helps us to confirm the path of needle and posture of a robot,are introduced.

In Recent years, CT-guided Interventional Radiology (IVR), which is a mininmal invasive medical procedure, attracts attention. A surgeon observes the perspective CT image and inserts a needle to patient. On the other hand, IVR has a problem that surgeons are exposed to radiation since they operate it close to a CT device. Therefore, we are developing a robot that performs needle inserting by remote control. Current needle holder unit for a CT-guided needle insertion robot has a risk that it might hurt a patient since a needle is always held firmly. To solve this problem, we propose a stiffness changeable gripper by jamming transition. In this paper, we describe a design and prototype of a stiffness changeable gripper to reduce the risk to patients.

There is a surgical method called CT-guided Interventional Radiology(IVR). We have been developing surgery support robot for CT-guided IVR. When this robot is used, there is a targeting phase in which the position of needle is navigated to the initial position before insertion. Currently targeting is done by doctor's manual operation. However, manual targeting is difficult. In order to solve this problem, we implemented a method of automatic targeting. However, due to assembling errors and mechanical stiffness, the accuracy of automatic targeting is not enough. In this paper, I calibrate kinematic parameters to improve accuracy of automatic targeting method. The accuracy after calibration is verified by experiment.

In recent years, interventional radiology (IR) which is a medical procedure has been attracting considerable attention. Doctors can perform IR percutaneously while observing the fluoroscopic image, such as CT and MRI images, of patients. Therefore, this surgical method is less invasive. However, doctors are exposed to strong radiation in the case of under CT-guidance. In order to overcome this problem, we developed remote-controlled IR assistance robot. The problem of the puncturing robot is inaccurate positioning of the tip of the needle, which causes the misdiagnosis and the complication, due to deflection of the needle and soft tissue. In this research, puncture method for minimizing the deflection force of the needle during puncture based on force sensor is proposed. First, the deflection of the needle was modeled as simply cantilever beam. Next, based on the deflection model, the target posture which minimizes the deflection force was derived. Finally, validity of the proposed method was verified based on the result of phantom puncture experiment.

Recently, surgical method using the image processing apparatus called Interventional Radiology(IR) is conducted well. IR surgery is a minimally invasive surgical method without an incision. Patients have less burden with IR surgery rather than that with conventional surgery. The surgical method of treating by puncturing the needle using computed tomograph(CT) apparatus requires the situation that the surgeon stands nearby the equipment. Therefore radiation exposure to doctor becomes a problem for doctors who engaged in IR surgery. Thus, we have developed a robot system which conducts IR surgery with remote operation. We report the function to change posture of a needle around tip of it, that is called remote center motion. In order to calculate desired trajectory of remote center motion, we derive Jacobian matrix between world coordinate system and tip of needle. Finally, effectiveness of proposed method is confirmed through experiment.

IVR has the advantage that invasiveness is low, therefore the number of IVR surgery has been increasing in recent years. In lung cancer treatments, however, it has the problem that doctors are exposed to radiation because IVR is conducted in CT equipment. The purpose of this study is to avoid the problem by operating remote steerable IVR robot. IVR robot with 5 DOF have been developed in the prior study. Previously, each joint was controlled independently. Therefore, when the posture of needle is changed, the position also should be corrected manually. To improve operability of IVR robot, the forward kinematics and the inverse kinematics is solved. Finally, accuracy of needle tip position is evaluated.

Interventional radiology is a minimally invasive image-guided procedure that can be performed percutaneously. When computed tomography (CT) is used as an image-guidance for interventional radiology, the radiation exposure is a major problem to an operator who stands close to a CT gantry. To solve this problem, we are developing a remote control needle puncture robot which has five degrees of freedom. However, evaluation of the positioning performance of the robot was not conducted. In this paper, evaluation criteria of positioning performance required for a needle puncture robot is determined, and the performance of the robot is evaluated.

Interventional Radiology (IVR) is a minimally invasive procedure that can be usually performed percutaneously. IVR has an advantage in that it is less invasive than conventional surgical intervention. On the other hand, IVR has a disadvantage in that operators are exposed to radiation during procedure when fluoroscopy or computed tomography (CT) is used as an image-guidance. To solve this problem, we are developing a remote controlled robot that handles a needle for CT-guided IVR. In this paper, our 3rd prototype IVR robotic system is reported. The 3rd prototype robot is consist of five degrees of freedom, three liner mechanism and two rotational mechanism. Especially, round guild rail is adopted for the 2nd degree of freedom. We also adopt parallel link mechanism for the hand part of the robot. The developed prototype was used in a real operation room with CT machine and achieve puncturing a phantom. The experimental result is also reported in this paper.

There is a surgical method called Interventional Radiology (IVR) as one of lung cancer treatments. It has a problem that doctors are exposed to radiation because IVR is conducted in CT equipment. In order to avoid the problem, a robotic IVR system that doctors conduct the operation with a robot is developed. An operation test is necessary to develop the robotic IVR system, however, an experiment with real patients is rejected based on ethic regulation. Therefore, we use a phantom in experiments instead of patients. A phantom is a model of human used for evaluation and adjustment of medical imaging equipments such as CT and MRI. However, ready-made phantoms can not be punctured, because they are only aimed for radiography and their surface are hard. Therefore a phantom for CT-IVR which can be punctured is developed.

Interventional Radiology (IVR) is a kind of surgical operation using real-time CT images and needles. IVR has an advantage that it is a lower invasive operation than a general surgical operation. On the other hand, IVR has a disadvantage that operators are exposed to radiation of X rays from a CT machine while they conduct the operation. To solve this problem, we propose developing a serial link robot as a remote controlled robot. In this paper, prototypes of robotic interventional radiology are described. First, specifications for the robotic IVR are described. Next, first version of prototype is designed and results of preliminary experiment for artifact are shown. In the second version, we have constructed a 3DOF mechanism and its driving system which is commanded by a joystick controller. Finally, experimental results of the developed prototype system are shown.

本研究の目的である「ロボットを用いた画像ガイド下骨穿刺における力センシングに基づく骨の自動穿刺アルゴリズム」を構築するために、おかやまメディカルイノベーションセンターにて生体ブタを用いた動物実験にて行った。既存の針穿刺ロボット（Zerobot）に骨穿刺用アームを取り付けて、さらにアーム先端に骨生検針を取り付けて、ブタの腸骨、脊椎、大腿骨に対してCTガイド下には穿刺試験を繰り返した。穿刺試験においては、規定の穿刺速度および針の軸周り回転速度で、また３種類の力制御アルゴリズムを用いて穿刺を行った。力制御アルゴリズムとは、ロボットアーム先端に取り付けた力センサの値が規定の値に達すると、ロボット制御機構が働き、針先にかかる力および穿刺速度を調整するものである。穿刺中のCT画像にて骨内へ針先を刺入できるかどうか、また事前に設定した標的に精確に穿刺できるかどうかを確認した。
同一骨であれば、力制御の値を大きく設定するほど、穿刺に要する時間は短くなった。また、同一の力制御アルゴリズムであれば、腸骨、脊椎、大腿骨の順で穿刺時間は短かった。この結果は主に骨の硬さを反映しているものと考えられ、硬い骨ほど力制御が早く作動し、穿刺に時間を要するものと思われた。さらに大腿骨は非常に硬く、力制御を低い値に設定すると穿刺を完遂することはできないことがあり、高い値に設定する必要があることが分かった。ただ、力制御の値があまりに高いと、穿刺はできるものの、針先が標的からずれる現象が生じ、精確な穿刺は困難であった。腸骨や脊椎においては、力制御の値により穿刺に要する時間に差はあったが、いずれのアルゴリズムにおいても精確な穿刺が可能であった。

本研究は外科的切除不応・不適の肺悪性腫瘍に対する経皮的肺マイクロ波焼灼術の有効性及び安全性を確認する単施設単群前向きオープン試験である。本邦におけるStageⅠ非小細胞肺がん及び原発巣や肺外転移が制御されている転移性肺腫瘍に対する治療としては、外科的手術の占める割合が大きい。一方で、耐術能が無い、あるいは手術拒否などで手術適応とならない患者も多く存在し、手術に替わる治療選択肢の拡充が必要と考えられる。耐術能が無い、あるいは手術を拒否している患者の原発性肺がんや肺転移に対してラジオ波焼灼術が広く行われている。しかし、腫瘍が血管や気管支に接していると、焼灼の温度が下がることにより再発の危険性が高まるという欠点を有している。マイクロ波焼灼術はラジオ波焼灼術よりも短時間で大きな焼灼範囲が得られることから、上記の欠点を克服できる可能性がある、
本年度は3患者に対して焼灼術を行い、重篤な有害事象なく退院することができた。経過観察期間内に再発は認めておらず、安全性と有効性の評価が行えた。2023年度も引き続き患者の登録を進めていく予定である。

Microwave ablation therapy is sometimes used as one of the treatment options for patients with lung tumors including both primary and secondary in Japan. However, there have been many uncertainties regarding the extent of tissue coagulation achieved through this therapy. The results of this study are expected to serve as one of the bases for determining ablation protocols (e.g., ablation time and ablation power) when treating lung tumors clinically. Additionally, while radiofrequency ablation has been known to have a reduction of ablation zone due to cooling effects from bronchi and blood vessels, it was previously believed that microwave ablation therapy has less cooling effects. However, the occurrence of multiple ablations of cooling effects in the present study demonstrates that cooling effects can indeed occur during microwave ablation therapy, providing significant information for clinicians.

我々はCT透視ガイド下針穿刺ロボットを研究開発している。本ロボットはこれまで、術者がコントローラを操作してロボットの動きをすべて遠隔操作していた。術者による遠隔操作では、精度良く標的に穿刺できることをファントム試験、動物試験など非臨床試験で実証した。2018年度にはFirst-in-human臨床試験を実施し、本ロボットは臨床での使用も可能であることを確認した。
我々はロボットを段階的に自動化することを目指している。これまでの研究により、医師が用手で針穿刺を行う際にどのように軌道修正を行っているのかについてのデータ解析を行い、適切なフィードバックを実施するための指針を得た。また、ロボットを用いた穿刺手技のうち、針先を刺入点へと移動させるターゲティング行程、および狙った標的へ向け針を挿入する穿刺行程において、一部を自動化する半自動化穿刺システムを開発した。
半自動化のシステムでは、 CT 画像上の腫瘍、刺入点、および針先位置の認識とポインティング操作や、ロボットを動作させるタイミングを送る操作は術者の判断により行う。一方で、刺入点へ針先を移動させる制御や、標的の方向に対する現在の針先方向のずれの算出、ずれを補正するための針姿勢修正動作ならびに穿刺動作、これらに伴う逆運動学計算は、ロボット内部の計算機および操作インタフェースのソフトウェアとして実装されている。
開発したシステムの有効性や妥当性は、岡山大学病院のIVRセンターにてファントム実験を実施することで検証している。

We developed a technique for robotic CT-guided out-of-plane needle insertion, and verified its accuracy. In the phantom experiment, we demonstrated that out-of-plane needle insertions performed using the robot were more accurate than manual insertions at the various angles. Furthermore, we succeeded in predicting the movement of the needle movement in vivo, and developed a method to correct the needle displacement in the tissue. In the animal experiment, robotic out-of-plane needle insertions were accurate in the in vivo procedure, particularly with adjustment during insertion.

The use of MRI-guidance for biopsy has several advantages such as no radiation exposure and excellent soft tissue contrast. A high field (1.2T) open MRI system has a suitable design for biopsy procedures and high imaging capability. Thus, a clinical study was conducted to evaluate the feasibility of MRI-guided biopsy using this system. In this study, MRI-guided biopsy was feasible and safe for targets of various locations in 10 patients.

A prospective clinical study was designed to confirm the safety and efficacy of cryotherapy for painful bone and soft tissue tumors and started after approval of the Okayama University Hospital Ethics Committee. Initially 10 patients were scheduled to be enrolled but only 2 were enrolled. The treatment efficacy was excellent in both cases, and marked pain improvement was observed. Pre-treatment Visual Analogue Scale was 2.0 and 9.0, respectively, and 4 weeks after treatment they reduced 0.8 and 1.3, respectively. Four weeks later, one patient had a complete response without tumor enhancement on MR images. In other case, although tumor enhancement remained slightly, most disappeared. With regard to safety, in both cases, anticipated Grade 4 adverse event occurred, but improved with no treatment and no sequelae. This therapy may be effective and safe for painful bone and soft tissue tumors

For adding a hook to an absorbable suture, a folded suture make it large in diameter, and a partially-cut suture make it brittle. A barbed suture can bring solutions to those problems. In addition, it is stiff enough to be pushed through a guiding needele by itself. To add radio-opaque nature to it, iodine contrast medium or barium sulfate were laid on it. Those radio-opaque sutures were visible on X-ray fluoroscopy image.
In a phantom examination, the radiopaque absorbable suture was easily placed near a target through a guiding needle. It was clearly visible on CT image. The barbed suture could not easily pull out from the phantom.
Therefore, we believe that we can make the guiding marker which is made of the barbed absorbable suture.

In 2013, a prototype robot was developed and phantom studies were performed. Robot was remotely controlled with controller and a needle was successfully inserted into a target 2 cm in size without radation exposure to a physician. In 2014 and 2015, the prototype robot was improved. In 2014, backlash during motion was improved. More needle insertion strength and faster insertion speed were applied. Usability of interface was also improved, and presentation of force sense to a physician was acheived. In 2015, hand section of the robot was made smaller and lighter. Further, mechanism of needle attachment and removal was simplified.

We performed a fundamental experiment of heating effect about nano-magnetic fluid in magnetic resonance imaging scanner with high magnetic field. The heating effects seen in the peripheral gantry group were higher than the central gantry group. Those results were thought to be derived from dielectric heating.

Radiofrequency ablation was performed for pulmonary aspergilloma. The procedure was safely done without any adverse events. Serial follow-up CT scan up to 26 months after the procedure showed that ablation zone continued to shrink. At 16 months, biopsy of the ablation zone was performed and revealed that the specimen was consisted mostly of abundant fibrotic tissue and partly of hypha. Thus, this study showed radiofrequency ablation was safe and effective as a treatment of pulmonary aspergilloma.

To determine the feasibility and image quality of intravenous ultrasonography, we conducted an animal experiment using five swine. Intravenous ultrasonography in hepatic veins of five swine was feasible. Intravenous ultrasonography in renal veins of two swine was also feasible. Intravenous ultrasonography demonstrated the structures within scanning range of intravenous ultrasonography more clearly than conventional ultrasonography.

From 2008 to 2010, thirty five tumors in 30 patients that show no local progression for more than 2 years were included in this study. In CT images, the size of ablation zone decreased after 3 or 6 months after radiofrequency ablation (RFA) compared to 1 month after the procedure. On the other hand, the accumulation of FDG in PET scan obtained 3 months after RFA, showed no significant difference compared to the pre-treatment image, but significant decrease after 6 months after the treatment. In conclusion, it is eligible that FDG-PET was performed 6 months than 3 months after RFA.
