核磁共振三维胆道成像技术在梗阻性黄疸诊断中的应用

The application of 3DMRC in diagnosis of obstructive jaundice

目的评价3DMRC 对梗阻性黄疸梗阻部位及原因的诊断价值。方法作者对24例梗阻性黄疸病人进行3DMRC 检查,与 ERCP 结果进行比较.所有病人均经手术证实。结果3DMRC 对梗阻性黄疸梗阻部位诊断正确率10096,梗阻原因诊断正确率95.8%.略高于 ERCP。各类病变均有特征性表现。结论 3DMRC 因图像质量高,不用造影剂。无相关并发症;对梗阻性黄疸的诊断是一种有效、安全的方法。

Objective To evaluate the diagnostic value of 3MDRC performing in finding positions and causes of obstructive jaundice.Method Twenty-four patients with obstructive jaundice accepted 3DMRC examination and the results were compared with those of ERCP.All patients were finally testified for the results with operations.Results The correct diagnostic rate of finding obstructive positions in 3DMRC is 100 %,and the correct rate of finding obstructive causes is 95.6 %.The rates mentioned above are a little higher than those of ERCP.All pathogenic changes have their own characteristic manifestations. Conclusion It is suggested that 3DMRC in diagnosing obstructive jaundice is quite effetive and safe be- cause of its clear pictures,without use of contrast medium and no complications.
