“…The accuracy of CT-guided biopsies has been evaluated in many studies. Taking into account the small number of our patients for the retroperitoneal biopsies, our results showed that the obtained results of MRI-guided biopsies can be compared with CT-guided biopsies [6,11,32,33].…”

“…Methods and techniques for various CT-guided or MRI-guided biopsies have been reported [3,5,11,13,18,21,22]. Many authors prefer an anterior access for CT-guided biopsies of abdominal lesions to avoid the large vessels [6]. Only a few authors use a dorsal approach to the retroperitoneal space.…”

The purpose of this study was to evaluate the safety and precision of MRI-guided biopsies of retroperitoneal space-occupying tumors in an open low-field system. In 30 patients with indistinct retroperitoneal tumors [paraaortic lesion (n=20), kidney (n=2), suprarenal gland (n=3) and pancreas (n=5)] MR-guided biopsies were performed using a low-field system (0.2 T, Magnetom Concerto, Siemens, Germany). For the monitoring of the biopsies T1-weighted FLASH sequences (TR/TE=160/5 ms; 90 degrees ) were used in all patients and modified FLASH sequences (TR/TE=160/13 ms; 90 degrees ) in ten patients. After positioning of the needle in the tumors 114 biopsy specimens were acquired in coaxial technique with 16-gauge cutting needles (Somatex, Germany). The biopsies were successfully performed in all patients without vascular or organ injuries. The visualization of the aortic blood flow with MRI facilitated the biopsy procedures of paraaortic lesions. The size of the lesions ranged from 1.6 to 7.5 cm. The median distance of the biopsy access path was 10.4 cm. Adequate specimens were obtained in 28 cases (93.3%) resulting in a correct histological classification of 27 lesions (90%). In conclusion, MR-guided biopsies of retroperitoneal lesions using an open low-field system can be performed safely and accurately and is an alternative to CT-guided biopsies.

Background The diagnosis of intrathoracic and abdominal masses is challenging when lesions are located behind major vessels. Endoscopic ultrasound (EUS) or endobronchial ultrasound (EBUS)‐guided transvascular needle aspiration (TVNA) provides a potentially useful diagnostic tool for such lesions. Data with respect to the safety and outcome of E‐TVNA are scarce. Hence, this meta‐analysis was conducted to assess the critical role of E‐TVNA for diagnosis of various lesions. Methods and Material A meta‐analysis was performed by pooling the data from studies obtained from comprehensive search of Medline, Embase, and Scopus from January 2000 to September 2022. The outcomes analyzed included sample adequacy, diagnostic accuracy and adverse events including bleeding. Results A total of 17 studies (n = 411) were included in the final analysis. The pooled rate of sample adequacy was 91.5% [95% confidence interval (CI): 86.8–96.2], while the pooled rate of diagnostic accuracy was 85.0% (95% CI: 78.9–91.2). The pooled rate of bleeding with E‐TVNA was 1.4% (95% CI 0.0–3.1%). All the episodes of bleeding were mild and resolved without any further intervention. There was no significant heterogeneity with respect to various outcomes and results were comparable on sensitivity analysis. Conclusions E‐TVNA offers a safe and accurate diagnostic modality for the diagnosis of mediastinal and abdominal lesions located on the other side of major vessels. Selection of potential candidates and close periprocedural observation are essential to improve the outcome.
