PDFAbstract
Objective To observe the imaging findings and diagnostic value of MRI and CT in patients with hilar cholangiocarcinoma. Methods The clinical data of 30 patients with hilar cholangiocarcinoma admitted in our hospital between March 2013 and February 2015 were retrospectively analyzed. The MRI and CT imaging findings of all patients with hilar cholangiocarcinoma were analyzed and compared. The diagnostic value of the two methods was explored. Results The display rates of MRI and CT for lesions were 100.00% and 60.00%, respectively, and the accuracy rates of the localization of hilar cholangiocarcinoma were 100.00% and 90.00% respectively. At the same time, MRI and CT of 30 patients with hilar cholangiocarcinoma all showed different levels of intrahepatic bile duct dilation. Conclusion Both of MRI and CT are effective methods in the diagnosis of hilar cholangiocarcinoma. However, MRI has more significant advantages over CT in displaying the sites of hilar bile duct tumors, size and scope of lumpand portal vein invasion, etc.. MRI has higher diagnostic value in hilar bile duct cancer.
