Abstract:
Objective To evaluate the role of MR imaging and MR cholangiopancreatography(MRCP) for the diagnosis of hepatic hilar cholangiocarcinoma and assessment of tumor resectability.Methods MR imagings were analyzed retrospectively and compared with surgical result in 20 patients with hepatic hilar cholangiocarcinoma.Results The tumor masses were found in the hilar regions on the MR images for 18 patients. It was found that only dilatation of the intrahepatic biliary tree and thickness of the bile duct wall for the other 2 patients. According to the Bismuth classifying, classification of MR was: typeⅠ (n=3), typeⅡ(n=4), type Ⅲ(n=6),type Ⅳ(n=7). Compared with the operative findings, the accurate ratio of classification was 80%, sensitivity specificity and coincidence was 75%, 75%,80% for the assessment of tumor resectablility by MR. Conclusion MRCP combined with MRI is very useful for diagnosis and classification of the hepatic hilar cholangiocarcinoma and assessment of tumor respectability.
