“…A proper definition of the access path is therefore substantial for a successful biopsy. 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].…”

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.

“…Since its introduction and broad use during the 1980s, image-guided percutaneous drainage (PD) has become part of the standard therapeutic armamentarium in patients with symptomatic abdominal and pelvic fluid collections [11,12]. In comparison to sequential CT guidance [13], CT fluoroscopic guidance allows for near real time visualization of needle or drain insertion similar to ultrasound (US), even in cases of difficult access routes and uncooperative patients [14][15][16]. Minimally-invasive percutaneous drainage can either have a temporizing effect in order to stabilize the patients' general condition before reoperation, or even a therapeutic effect, circumventing revision surgery [8,17].…”

Low-Dose CT Fluoroscopy-Guided Drainage of Deep Pelvic Fluid Collections after Colorectal Cancer Surgery: Technical Success, Clinical Outcome and Safety in 40 Patients

et al. 2023

Purpose: To assess the technical (TS) and clinical success (CS) of CT fluoroscopy-guided drainage (CTD) in patients with symptomatic deep pelvic fluid collections following colorectal surgery. Methods: A retrospective analysis (years 2005 to 2020) comprised 43 drain placements in 40 patients undergoing low-dose (10–20 mA tube current) quick-check CTD using a percutaneous transgluteal (n = 39) or transperineal (n = 1) access. TS was defined as sufficient drainage of the fluid collection by ≥50% and the absence of complications according to the Cardiovascular and Interventional Radiological Society of Europe (CIRSE). CS comprised the marked reduction of elevated laboratory inflammation parameters by ≥50% under minimally invasive combination therapy (i.v. broad-spectrum antibiotics, drainage) within 30 days after intervention and no surgical revision related to the intervention required. Results: TS was gained in 93.0%. CS was obtained in 83.3% for C-reactive Protein and in 78.6% for Leukocytes. In five patients (12.5%), a reoperation due to an unfavorable clinical outcome was necessary. Total dose length product (DLP) tended to be lower in the second half of the observation period (median: years 2013 to 2020: 544.0 mGy*cm vs. years 2005 to 2012: 735.5 mGy*cm) and was significantly lower for the CT fluoroscopy part (median: years 2013 to 2020: 47.0 mGy*cm vs. years 2005 to 2012: 85.0 mGy*cm). Conclusions: Given a minor proportion of patients requiring surgical revision due to anastomotic leakage, the CTD of deep pelvic fluid collections is safe and provides an excellent technical and clinical outcome. The reduction of radiation exposition over time can be achieved by both the ongoing development of CT technology and the increased level of interventional radiology (IR) expertise.

“…Akciğer lezyonlarında BTF'nin avantajı kostadan sıyrılarak hastanın nefes alması ile yer değiştiren nodüle doğru zamanda iğnenin hedeflenmesi ve örnek elde etme sırarsında nodül ile iğne ucunu aynı anda gösterilerek nodülden örnek alındığından emin olunmasıdır [4,[23][24][25]. BTF karaciğerin intravenöz kontrast enjeksiyonu sonrası geçici kontrast tutan lezyonlarında, karaciğerde ulaşılması zor, diyafram ya da kritik vasküler yapılara komşu kitlelerden biyopsi almak için kullanılabilir [26,27]. BTF ayrıca hastanın nefes almasıyla yer değiştiren ya da kısmen bağırsaklarla çevrili mesenterik veya omental lezyonlardan iğne ile örnek alınmasına yardımcı olabilir [4].…”

CT fluoroscopic guidance for percutaneous needle placement into abdominopelvic lesions with difficult access routes

Abstract: CTF appears to be a valuable tool to dynamically assist percutaneous needle placement into lesions that may be considered difficult with standard CT assistance.
