【摘要】目的探讨磁共振胆胰管成像诊断小儿先天性胆管扩张症的价值。方法回顾性分析经手术病理证实27例小儿先天性胆管扩张症,对MRCP的影像征象进行总结分析。结果 27例先天性胆管扩张症中I型18例,%,IV型9例,%。扩张的胆总管直径均在2cm以上,~(11例),%。~。扩张胆总管以囊状扩张为主(21例),%。受累位置在胆总管中段及上中段最常见(17例),%。MRCP术前诊断准确率为100%。结论 MRCP为小儿提供了无创伤无辐射的影像检查,术前诊断准确率高,能为外科手术提供重要的影像资料。

[Abstract] Objective To study the application value of ic resonance cholangio- pancreatography (MRCP) in diagnosis of congenital choledochal cyst in children. Methods 27 children with congenital choledochal cyst proved by surgery and pathology underwent MRCP examination were reviewed, all the image data were analyzed retrospec
tively. Results In 27 cases, 18 of them were type I,about % rate,9 were type IV,% rate. The diameter of mon bile duct in all cases was more than 2cm, most of them were ~(11 cases),% dilated bile duct inside the liver were ~ dilatation was the mon form(21cases),% most familiar positions involved were middle and uper segments(17cases),about % preoperation diagnostic percentage of MRCP is 100% rate. Conclusion MRCP is a nonvasive examination without radiation for children with a high accuracy of localizing diagnosis and qualitative diagnosis in children with congenital choledochal cyst. The detail image data ma
