Abstract    Objective    To study enhanced MRI and MRCP findings of hepatic hilum cholangiocarcinoma and their preoperative evaluation value. Methods    Enhanced MRI and MRCP findings in 30 patients with hepatic hilum cholangiocarcinoma proved pathologically between June 2006 and October 2009 at General Hospital of Guangzhou Military Command of PLA were analyzed retrospectively. The preoperative evaluations and operative results were compared. Results    All patients were found to have soft tissue mass at porta hepatis with delayed enhancement, and intrahepatic biliary duct dilation was seen. Enhanced MRI and MRCP imaging could find infiltrated bile duct and blood vessel objectively, and metastatic tumor also could be seen availably. The sensitivity, specificity and accuracy of preoperative evaluation in all patients with hepatic hilum cholangiocarcinoma were 81.8％ and 91.6％ and 86.9％. Conclusion Enhanced MRI and MRCP are valid methods in the preoperative evaluation of hepatic hilum cholangiocarcinoma.
