| 摘 要： | 目的:总结肝门部胆管癌的低场MRI影像表现,以提高对肝门部胆管癌的认识。方法:收集经手术病理证实的肝门部胆管癌21例,均有完整的MRI影像资料。结果:MRCP对肝门部胆管梗阻水平定位准确率达100%。21例肝门部胆管癌均表现为肝内胆管不同程度"软藤样扩张",肝门部胆管狭窄、管壁增厚或软组织肿块;6例MRI肝门部可见稍长T1、稍长T2的肿块影,15例未发现明确肿块;增强扫描5例可见肿块延迟期缓慢持续强化,14例表现为管壁增厚强化、管腔狭窄。结论:低场MRI是检查肝门部胆管癌的有效方法,联合应用MRCP可显示肝门部胆管癌的特征性改变。

| Abstract: | Objective:To explore the low field MRI imaging of findings of hilar cholangiocarcinoma,and improve the diagnostic accuracy.Methods:Twenty-one cases of hilar cholangiocarcinoma proved by pathology were studied,all the cases had intact MRI materials.Results:The localized accuracy of MRCP for hilar cholangiocarcinomas was 100%.Dilatation of the intrahepatic biliary tree in vary degree like soft vine in all 21 cases and hilar bile duct narrowed,occluded or soft tissue mass;precontrast MRI found hilar masses wit... |
