    ¡¾Abstract¡¿ AIM: To evaluate the clinical value of magnetic resonance cholangiopancreatography(MRCP)combined with magnetic resonance imaging (MRI) in diagnosing biliary obstruction. METHODS: A total of 52 cases with choledocholithiasis, hepatolithiasis, carcinoma of the pancreatic head, carcinoma of the choledoch, carcinoma of the gallbladder, hepatoblastoma and choledochocyst were examined by MRCP combined with MRI and the results of MRCP and MRI were compared with those of operation. A retrospective study was conducted of preª²operation qualitative and orientative diagnosis by MRCP combined with MRI. RESULTS: ¢Ù The demonstrating rate of intrahepatic bile duct calculus was 87.5% and that of other parts was 100%. ¢Ú The rate of orientative diagnosis of choledocholithiasis was 94.7%, that of intrahepatic bile buct calculus was 75.0% and that of other parts was 90.9%-100%. CONCLUSION: MRCP combined with MRI, a noninvasive technique with excellent accuracy in the diagnosis of biliary obstructions and their causes, is of high value in the diagnosis of biliary obstruction. ......
