MR cholangiopancreatography and MR imaging in the diagnosis of extrahepatic cholangiocarcinoma

摘要: OBJECTIVE: To evaluate the imaging features of MR Imaging (MRI) and cholangiopancreatography (MRCP) their clinical value in diagnosis extrahepatic cholangiocarcinoma. METHODS: MRI was performed 54 patients with cholangiocarcinoma proved surgically pathologically, MRCP 44 patients, Gadolinium-enhanced 29 patients. MRI, pathological findings were analyzed retrospectively. RESULTS: By mass shown (n = 39) all bile duct thickened 13) ones revealed calcified focus 22). MRCP, interrupted, abruptly cut-off or cone-like changes 16), beak-like mouse tail 26) tumbler mouth appearance 2) shown. The distal to obstruction observed Of examined by combination correct tumor localization made 52 (96.3%) judgement nature 50 (92.6%). CONCLUSION: Conventional is an effective supplement combined able significantly improve diagnostic accuracy examination.
