| 摘 要： | 目的 探讨MRCP对良性梗阻性黄疸的临床定性诊断价值。方法 用Philips 1.5T超导型磁共振成像仪对 12 8例良性梗阻性黄疸患者进行常规MRI及MRCP检查。 12 3例经手术或ERCP病理证实 ,5例临床随访证实。结果 MRCP对良性梗阻性黄疸定位诊断准确率 10 0 % ,定性诊断准确率 90 .6%。枯枝征在良性梗阻性黄疸中特异性 10 0 %、准确性 95 .3 %、敏感性 85 .7%。结论 MRCP在良性梗阻性黄疸中的定性诊断中枯枝征可作为一种特异性征象

| Abstract: | Objective To investigate the qualitative diagnostic value of MRCP in patients with benign obstructive jaundice.Methods MRCP and conventional MR images were performed in 128 patients with benign obstructive jaundice on a superconductive MR scanner (Plilips medical systems Inc. Eclipse. 1.5T) . Final diagnosis was confirmed by surgical and histopathological findings in 123 patients and other 5 patients by follow-up.Results The accuracy of location diagnosis of MRCP was 100%; the qualitative diagnosis was 95.3%. The specificity, accuracy, sensitivity of the deadwood-sign for diagnosis of benign obstructive jaundice were 100%, 95.3%, 85.7% respectively. Conclusion The deadwood-sign was a specific indicator in MRCP of benign obstructive jaundice. |
