摘　　要：目的探讨MRI平扫、增强及磁共振胰胆管成像(MRCP)在肝门部胆管癌诊断中的价值。方法收集经手术病理证实的肝门部胆管癌病例13例,回顾分析其影像学表现,MRI检查采用T2加权(T2WI)和T1加权(T1WI)序列平扫、3DT1加权加脂肪抑制(T1WI-FS)动态增强扫描,所有病例均做MRCP。结果13例肝门部胆管癌均可见肝门包块,肝内胆管扩张,动态增强扫描显示12例包块呈逐渐强化。1例动脉期显示强化。MRCP定位诊断率100%。按Bismuth分型,Ⅱ型6例,Ⅲa型2例,Ⅲb型3例,Ⅳ型2例。病理证实高分化腺癌7例,中分化腺癌4例,低分化腺癌2例。结论MRI平扫及动态增强扫描并与MRCP结合对肝门部胆管癌有较高的诊断价值。Objective To assess the diagnostic value of MRI and MRCP in hilar cholangiocarcinoma. Methods The data of MRI, 3D DCE and MRCP in 13 cases of hilar cholangiocarcinoma proved surgically and pathologically were analysed retrospectively. Results MRI findings of hilar cholangiocarcnoma demonstrated high-grade intrahepatic ductal dilatation and hilar mass. Twelve cases with hilar mass showed progressive enhancement on 3D dynamic contrast enhancement images. One case showed en- hancement in arterial phase. The accuracy of MRCP in locating the obstruction was 100%. According to Bismuth categories： type Ⅱ , six cases, type Ⅲ a, two cases, type Ⅲ b, three cases, type Ⅳ, two cases. The pathology showed seven cases of high differen- tiated adenocarcinoma, four cases of media differentiated adenocarcinoma, and two cases of low differentiated adenocarcinoma. Conclusion MRI and 3DCE, combined with MRCP, are valuable in the diagnosis of hilar cholangiocarcinoma.
