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,占66.7%,IV型9例,占33.3%。扩张的胆总管直径均在2cm以上,3.1cm～4.0cm最多见(11例),占40.7%。肝内胆管扩张1.0～4.0cm。扩张胆总管以囊状扩张为主(21例),占77.8%。受累位置在胆总管中段及上中段最常见(17例),占63.0%。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。Objective To study the application value of magnetic resonance cholangiopancreatography （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 retrospectively. Results In 27 cases, 18 of them were type 1,about 66.7% rate,9 were type Ⅳ,about33.3% rate. The diameter of dilated common bile duct in all cases was more than 2cm, most of them were 3.1 -4.0cm（l 1 cases）,about40.7% rate.the dilated bile duct inside the liver were 1.0~4.0cm.Bag dilatation was the most common form（21 cases）, about77.8% rate.The most familiar positions involved were middle and uper segments （17cases）,about 63.0% rate.The 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 may be helpful for surgical management.
