Methods To collect 26 cases 3.0T MRI and MRCP imaging data and Ultrasound diagonosis of hilar cholangiocarcinoma confirmed by clinical surgery and pathology, 12 of them had 3D-VIBE dynamic contrast-enhanced scanning, 10 conventional CT examination, compared with the pathological results so as to compare the clinic value of them. Results The accuracy of plain MR scan combined with MRCP for evaluating the sites and the causes were 100% and 92.3% respectively，whereas ultrasound 92.3% and 65.4% respectively, it is statistical significantly different in qualitative accuracy(P0.05). 12 cases of 3D-VIBE dynamic contrast-enhanced MRI found 3 lesions more than plain MR scan; 2 cases of misdiagnosis in 10 cases of CT scanning but MR examinations were qualitatively correct. Conclusion 3.0T plain MR scan and MRCP is great clinical diagnostic value for hilar cholangiocarcinoma in diagnosis and classification,it has higher clinic value than Ultrasound diagonosis as well as CT examination, which combined with 3D-VIBE dynamic sequences can clearly demonstrate the arterial phase, the portal venous phase and parenchymal phase, It is not only useful to find small lesions which can not be found in plain scan，but also provide the blood supply of lesions and higher value for clinical imaging information. 　　[Key words] magnetic resonance imaging; hilar cholangiocarcinoma magnetic resonan- ce cholangiopancreatography; three-dimensional volumetric interpolated breath-hold examination 　　肝门部胆管癌是常见的胆道肿瘤，由于其特殊的解剖位置和毗邻关系，临床诊断和治疗均有一定难度。目前外科根治性切除仍然是首
