ABSTRACT
PURPOSE:
To evaluate the diagnostic role of a three-dimensional MR cholangiopancreatography(MRCP) over endoscopic retrograde cholangio- pancreatography(ERCP) in various extrah-epatic biliary disease. MATERIALS ANDMETHODS:
MRCP and ERCP were performed in 45 consecutive patients with suspected extrahepatic biliary diseases. MRCP was obtained using a reverse fast imaging with a steady-state free precession (reverse FISP PSIF) sequences, and then images were reconstructed by standard MIP algorithm. The predictability of biliary dilatation and level of obstruction of MRCP was evaluated using ERCP as a gold standard. The accuracy distinguishing malignant from benign lesions, and overall diagnostic accuracy were compared between MRCP and ERCP.RESULTS:
The sensitivity, specificity and accuracy of MRCP in predicting biliary dilatation were 94.6%, 75.0% and 91.1%, respectively. The level of obstruction was accurate in 87.0% with MRCP. The sensitivity, specificity and accuracy MRCP and ERCP in distinguishing malignant from benign lesions were 76.2%, 87.5% and 82.2% and 71.4%, 83.3% and 77.8%, respectively. The overall diagnostic accuracy was 60.0% with MRCP and 55.6% with ERCP.CONCLUSION:
3D MRCP shows a good diagnostic value compared to that of ERCP, and can replace a ERCP.
