Preoperative localization value of MRI and MRCP in patients with congenital biliary dilatation:a report of 30 cases / 中国基层医药

ABSTRACT

Objective To evaluate the preoperative localization value of MRI and MRCP for congenital biliary dilatation.Methods 30 cases of congenital biliary dilatition diagnosed by either surgery or pathology were studied.MRI and MRCP findings of all these cases were analyzed.Results MRI and MRCP preoperative examination manifested the place of choledochal cyst and the relation between choledochal cyst and the biliary ductal system around in all 30 patients.Through surgery findings as follow,using Todani's classification,the accuracy of MRI and MRCP in evaluating the site and classification of congenital biliary dilatation was 100%,the accurate visualization rate of pancreatic duct was 73.3% and the junction of pancreaticobiliary duct was 33.3%.Conclusion MRI and MRCP manifestations are very reliable in preoperative localization of congenital biliary dilatation.
