MR水成像对胰胆道系统病变诊断价值

Diagnosis Value of MR Hydrography Cholangio-pancreas-tomography in Biliary Lesion

摘要: <b<目的</b< 评价MR水成像在胆道系统病变中的临床诊断价值。 <b<方法</b< 采用重T2加权MR水成像技术对36例患者行MRCP检查,图像经三维最大信号强度投影及三维表面遮蔽显示技术后处理。 <b<结果</b< 水成像定位诊断率达100%,定位诊断率为86.6%。此技术可清楚显示胰胆管的形态,显示各种胆道疾病的异常改变,诊断正确性高。 <b<结论</b< MRCP对胆石症、恶性胆管梗阻及先天性胆总管囊肿等胆系疾病的诊断价值高于其他影像检查。

Abstract: <b<Objective</b< To study the diagnostic Value of MR evaluate clinical Cholangio-pancreatography in the Biliary Lesion. <b<Methods</b< MRCP were performed in 66 cases ues a heavy T<sub<2</sub< Weighted MR hydrography technique, the images were post-processed by three dimensional maximum intensity projection and three dimensional surface shaded display. <b<Results</b< The accuracy of MRCP for evaluating this disease was 100%,and for the cause of disease was 86.6%. <b<Conclusion</b< The diagnostic value of MRCP for choledo-lithiasis, malignant bile duct obstruction and congenital common bile duct cyst is superior to that of other imaging examinations.
