We evaluated the diagnostic accuracy of magnetic resonance cholangiography (MRC) in the diagnosis of bile duct calculi and stenosis. Two-dimensional fast spin echo (FSE) MR cholangiograms were performed using torso multicoil array as a surface coil and respiratory triggering in 50 patients suspected of having bile duct disease. Coronal and axial images were acquired and reviewed prospectively by two radiologists. Direct cholangiographic correlation (endoscopic retrograde cholangiopancreatography [ERCP], intraoperative cholangiogram, percutaneous transhepatic cholangiogram) and surgery were available for comparison and were reviewed by two radiologists. The sensitivity, specificity and accuracy of MRC in diagnosing bile duct dilatation, choledocholithiasis and stenosis were evaluated. It yielded a sensitivity and a specificity of 100% in diagnosing bile duct dilatation. In the diagnosis of choledocholithiasis, MRC yielded a sensitivity of 95%, a specificity and an accuracy of 96%. Bile duct stenosis was diagnosed with a sensitivity and a specificity of 100%. We concluded that MRC exhibited high accuracy in diagnosing bile duct stenosis and choledocholithiasis.
Objective: To assess the utility of comput- ed tomography (CT)-guided percutaneous drainage in the management of tuberculous and non-tuberculous deep pelvic abscesses. Material and Methods: Twelve patients with deep pelvic abscesses were drained under CT guidance. Nine patients were drained with an indwelling catheter of size ranging from 8 to 14 F. Needle aspiration and lavage were performed in 3 patients. Results: Successful drainage was accomplished in all the patients. A single-session catheter drainage was sufficient in all the cases. In 4 out of 12 patients the abscess was of tuberculous aetiology and all were effectively managed with indwelling catheter drainage. Conclusion: CT-guided percutaneous drainage of pelvic abscesses with appropriate chemotherapy is an easy, safe and effective alternative to surgery in the treatment of tuberculous and nontuberculous pelvic abscesses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
