Abstract:
Objective Comparing the diagnostic values for the malignant obstruction diseases of biliary tract between endoscopic retrograde cholangiopancreatography(ERCP)and MR cholangiopancreatography (MRCP). Methods Parallel analysis for the ERCP and MRCP data of 142 malignancies confirmed by surgery and/or ERCP among 383 biliary tract patients was retrospectively carried out. Results MRCP and ERCP were performed with exploration of 137 cases,showing the total conformity of 96.4%; together with localization conformities of 92.3% and 87.3%,qualitative conformities of 78.5% and 89.8% respectively. Conclusions In diagnosing the malignant obstructing disease of biliary tract,MRCP has the advantages in convenience,safety and low false negative,but with higher false positive than ERCP; however,if combined with ERCP can get higher positive conformity.(J Intervent Radiol,2007,16: 673-675)
