| 摘 要： | 目的:分析胆道闭锁的MRI表现,评价其诊断价值.材料和方法:回顾性分析7例确诊为胆道闭锁患儿的MRI资料,观察其肝内外胆道、肝门部结构及胆囊的显示情况.结果:所有的患儿均未见到完整的肝外胆道.其中,3例冠状面T2WI可见肝门部三角形高信号影;5例门静脉周围增宽,肝门部出现条索状长T2信号;6例可见小胆囊,1例胆囊未显示.结论:胆道闭锁的MRI表现具有一定的特征性,多方位观察均未发现完整的肝外胆道时,应高度怀疑胆道闭锁.

| Abstract: | Purpose: To analyze the MRI findings of biliary atresia (BA) and evaluate the value of MRI in the diagnosis of BA. Materials and Methods: MR imagings of BA in 7 cases were retrospectively analyzed. Intrahepatic bile duct, extrahepatic bile duct, porta hepatis and gallbladder were observed. Results: The entire extrahepatic bile duct can not be visualized in all cases. In 3 cases, T2WI showed a triangular area of high signal intensity confined to the porta hepatis on coronal plane. Periportal thickening and high signal intensity around porta on T2WI was observed in 5 cases. Six cases had small gallbladder, while gallbladder could not be delineated in the other one. Conclusion: MRI findings of BA had some characteristics. Nonvisualization of entire extrahepatic bile duct was highly suggestive of BA. |
