Background: Contrast enhanced magnetic resonance cholangiography is a novel technique and promising method in demonstrating biliary tree anatomy and evaluating biliary disorders. However, to date, there are a limited number of studies that have focused on the impact of this technique. Aims: We aimed to evaluate the additional role of contrast enhanced MR cholangiography (MRC) and compare contrast enhanced MRC with T2-weighted (w) magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of biliary disorders. Study Design: Diagnostic accuracy study. Methods: The T2w-MRCP and contrast enhanced MRC sequences of 31 patients whose gold standard test results were available were scored visually for the existence of pathological findings with regard to any of the biliary diseases. Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) was used as the contrast agent. The correlation values were determined according to the statistical analysis made from those scores and the sensitivity, specificity and accuracy values of each sequence were detected as well. Results:We detected that the correlation values with gold standard methods of contrast enhanced MRC sequences were significantly higher than the ones of T2w-MRCP sequences. The correlation ratios of T2w-MRCP sequences were between 26 and 34%, while those for contrast enhanced MRC sequences were between 81 and 83% for the first reader and the correlation ratios of T2w-MRCP sequences were between 10 and 61%, whereas those of contrast enhanced MRC were between 79 and 81% for the second reader The mean sensitivity, specificity and accuracy values of T2w-MRCP sequences were 14.3-42.5%, 85-89.2% and 59.3-72.5%, respectively, while the mean sensitivity, specificity and accuracy values of contrast enhanced MRC sequences were 100%, 86.7% and 93.2-93.3%, respectively. Conclusion: We suggest that obtaining of contrast enhanced MRC sequences in addition to the T2w-MRCP can be useful in the diagnosis of many diseases in relation with biliary tree.

Title of the article: Role of MRCP in hepatobiliary pathology in correlation with ERCP. Aim: To determine diagnostic accuracy of MRCP as compared to ERCP for evaluating biliary duct disorders using the specificity, sensitivity, positive and negative predictive values. Patients and methods: From January 2010 to July 2016, 168 patients with suspected biliary pathology were included in this prospective and retrospective observational study. MRCP was performed prior to ERCP in all the patients included in this study. Results: MRCP had a 94.09% sensitivity , 94.03 % specificity ,91.30% positive predictive value 95.96 % negative predictive value (NPV) and 94 % accuracy rates in diagnosing biliary calculus. MRCP had a 92.31% sensitivity , 95.35%, specificity , 85.71% positive predictive value 97.62% negative predictive value (NPV) and 94.64% accuracy rates in diagnosing tumours/cyst MRCP had a 74.51 % sensitivity , 97.44 %specificity , 92.68%, positive predictive value 89.76%negative predictive value (NPV) and 90.48%, accuracy rates in diagnosing tumours/cyst other biliary disorders like CBD stricture, periampullary diverticulum and others. Conclusion: MRCP is an accurate investigation compared with diagnostic ERCP for the assessment of biliary pathologies.

“…MRCP is comparable with invasive endoscopic retrograde cholangiopancreatography (ERCP) for diagnosis of extrahepatic bile duct abnormalities. In patients with biliary-enteric anastomoses, MRCP is also accurate in detection of pancreas divisum [6]. EUS-guided pancreaticogastrostomy (EPG) has been reported as an alternative to surgery in cases of pancreatic stricture where ERCP is unsuccessful.…”

Background: Recently there has been growing interest in the duct system of pancreas as concerns its relationship with various disease processes as well as newer investigatory and treatment modalities related to them.This study has been aimed at evaluating the anatomy of the pancreatic duct system, thus identifying the variants to improve our knowledge of it and make things easier. The pancreas is formed by the fusion of the ventral and dorsal anlage, and a wide spectrum of anomalies or anatomical variations may appear related to this complicated process of fusion: e.g., agenesis, aplasia of a pancreatic anlage, hypoplasia, annular pancreas, pancreas divisum or nonfusion of the ventral and dorsal duct system, pancreaticobiliary maljunction, etc. Every endoscopist who engages in pancreatography or related diagnostic and therapeutic procedures should always be aware of all sorts of anatomical variations he or she might encounter.
