摘要
目的 评价磁共振胰胆管成像 (MRCP)对梗阻性黄疸梗阻部位及原因的诊断价值。方法 对 36例梗阻性黄疸患者行MRCP检查。所有患者均经手术及病理证实。结果 MRCP对梗阻性黄疸梗阻部位诊断正确率为 10 0 % ,梗阻原因诊断正确率为6 6 .7% ,MRCP结合 MRI诊断正确率达 80 .6 %。各类病变均具有其特征性表现。结论 MRCP图像质量高 ,不需造影剂 ,无相关并发症 ,故对梗阻性黄疸的诊断安全可靠。 MRCP结合 MRI可有效提高对梗阻性质判断的准确性。
Objective To evaluation the diagnosis value of magnetic resonance cholangiopancretography(MRCP) technique in finding the position and causes of obstructive jaundice.Methods Thirty-six patients with obstructive jaundice were examined by MRCP under a fast spin egho,heavy T 2 weighted fast spin echo(FSE) sequence.The images were postprocessed by maximum intensity projection(MIP).All patients were finally testified by operations.Results The correct diagnosis rate of obstructive position in MRCP was 100%,and the corret rate of finding obstructive causes 66.7%,MRCP combined with MRI raised the acurracy of diagnosis of obstructive causes(80.6%).All pathogenic changes had their own characteristics.Conclusion It is suggested that MRCP in diagnosing obstructive jaundice is quite effective and safe because of its clear image,without the use of contrast medium and no complications.
