磁共振胰胆管成像对胆道梗阻性疾病的诊断价值

Value of MR cholangiopancreatography in diagnosis of bile duct obstruction.

目的 评价磁共振胰胆管成像 (MRCP)在胆道疾病中的临床诊断价值。方法 采用GE 0 5Tesla超导VectraⅡ磁共振机 ,体线圈。用重T2 MR水成像技术MR胰胆管造影 131例。其中 32例为正常组 ,其余 99例为临床拟诊胰胆管疾病者。并对照手术结果进行分析。结果 MRCP定位诊断率达 10 0 % ,定性诊断率为 85 9%。此技术可清楚显示胰胆管的形态 ,展示各种胆道疾病的异常改变 ,诊断正确性高。结论 MRCP是安全、可靠的非侵袭性的检查方法 ,不用造影剂即能较好地估价胰胆系统的解剖和病理变化 ,具有较高的临床应用价值。

Objective To evaluate the clinical diagnostic value of bile duct obstruction by MRCP.Methods In 131 cases,heavily T 2 weighted MRCP was performed with fast-spinecho(FSH).32 cases were normal.99 cases had pancreatic or biliary diseases.The results of MRCP were analysed.Results The accuracy of MRCP for evaluating the site of disease was 100%,and for the cause of diseases was 85.9%.Conclusion MRCP is a reliable noninvasive method for depicting the pancreatic-bile ducts without iodinated contrast material.
