磁共振水成像在胰胆道系统病变中的应用

目的评价MR水成像在胰胆道系统病变中的临床应用。方法采用重T2加权MR水成像技术对66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。结果水成像定位率达100％，定性诊断率为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，诊断符合高。结论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。

The applicable value of MR hydrography cholanglo-pancreas tomography in biliary lesion

Objective To study the diagnostic Value of MR hydrography cholangio- pancreas tomography in the Biliary Lesion. Methods MRCP were performed in 66 cases using a heavy T2 weighted MR hydrography technique. The images were post- processed by three dimensional maximum intensity projection and three dimensional surface shaded display. Results The accuracy of MRCP for evaluating this disease was 100%, and for the cause of disease was 86.6%. Conclusion The diagnostic value of MRCP for choledo-lithiasis, malignant bile duct obstruction and congenital common bile duct cyst is superior to that of the other imaging examinations.
