先天性胆管扩张症的MRCP诊断及意义

目的 探讨MRCP对先天性胆管扩张症的诊断价值及意义。方法 回顾性分析13例先天性胆管扩张症的MRCP影像资料，并与B超、ERcP或手术结果进行对照分析。结果 13例MRCP表现均有不同程度的胆管扩张，直径1．5～10．0cm。其中，单纯胆总管扩张8例，肝内，肝外胆管同时扩张2例，单纯肝内胆管扩张3例。与B超，ERCP或手术结果基本一致。结论 MRCP能清楚显示扩张胆管的部位，形态及与周围组织结构的关系，优于其他影像学检查，为临床手术提供可靠依据。

MRCP diagnosing congenital cholangiectasis and its significance

Objective To investigate the diagnostic value of MRCP in congenital cholangiectasis and its significance. Methods MRCP imaging data of 13 cases with congenital cholangiectasis were analyzed retrospectively and compared with ultrasound,ERCP and operative results. Results On MRCP, 13 cases all showed biliary dilatation,whose diameters ranged from 1.5cm to 10cm, including 8 cases of simple dilatation of common bile duct, 3 cases of simple dilatation of intrahepatic bile duct and 2 of mixed type,which was similar to ultrasound,ERCP or operative result. Conclusion MRCP, a better imaging technique, accurately shows not only the pathological position and shape of cholangiectasis but also the relationship between biliary duct and its adjacent organs,thus offers a reliable foundation for operation.
