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

... ded 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.
