Abstract:
Objective To evaluate the MR cholangiopancreatography (MRCP) diagnosis for cholangitis caused by clonorchis sinensis. Methods Fifty-four cases with cholangitis caused by clonorchis sinensis were examined by MRCP (3D FASE-Heavy T 2WI sequence). The results of MRCP were compared with that of ERCP, laparoscopy, and pathology. Results The diagnostic accuracy for the cause of the disease was 88.9%. Main findings on MRCP included slight dilation of the intra-hepatic biliary duct ( n =46), small cystiform dilation of peripheral biliary ending ( n =43), extra-hepatic biliary dilations ( n =15) and strictures ( n =19), and low signal intensity filling defect in the common bile duct and gallbladder ( n =6). Conclusion MRCP of biliary tree images can be obtained with 3D FASE Heavy T 2WI sequence in considerable details. The characteristic of the cholangitis caused by clonorchis sinensis on MRCP was the slight dilation or stricture of extensive intra-hepatic biliary duct, combined with small cystiform dilation of peripheral biliary ending. MRCP was an ideal technique in diagnosing the disease.
