Objective To evaluate the cllnical value of MR cholangiopancreatography (MR CP) in diagnosis of pancreaticobiliary duct disease. Methods MRCP was performed in fihy- eight cases, including sixteen persons as comparison and forty - two patients with various pancreaticobiliary duct diseases. MRCP uses non - breath - hold Turbo Spin - Echo (TSE) sequence with respiratory - triggering and fat - suppression techniques. Three - dimensional (3D) reconstruction was used for postProcedure processing with a maximum - intensity -projection (MIP) algorithm. ResuIts MRCP examination was succeeded in all 58 cases. In 16persons as comparison, gallbladder, extrahepatic bile duct and partial intrahePatic bile duct or main pancreatic duct were visualized clearly. In 42 patients with pancreaticobiliary duct disease, MRCP can exhibit the imaging characteristic of various pancreaticobiliary duct diseases and the total diagnostic accuracy was 85.7%. The accuracy of MRCP in the detection of the degree and location of bile duct obstruction was 100%. The accuracyof MRCP for evaluating the causes ol obstruction was 83.8%. In the diagnosis of choledocholithiasis and malignant bile duct obstruction, the diagnostic accuracy of MRCP was 90.9% and 80.0%, respectively. ConcIusion MRCP examination has a high success rate and can depict pancreaticobiliary duct clearl,. Because of reliable value in diagnosing pancreaticobiliary duct diseases, MRCP may provide an efjcient alternative to direct cholangiopancreatography, especially when the diagnostic ERCP and percutaneous transhepatic cholangiography (PTC) are unsuccessful or inadequate.
