摘　　要：目的:比较1.5T超导磁共振True FISP序列与MRCP在诊断梗阻性黄疸中的价值。方法:对临床怀疑梗阻性黄疸120例的MRCP与True FISP序列分别进行阅片诊断,再结合其他序列进行诊断;最后与病理结果进行对比分析。结果:MRCP与True FISP序列判断有无梗阻及梗阻部位的敏感性和特异性均很高,但True FISP序列的正确定性率(61.7%)高于MRCP(54.2%)。如结合TlWI、T2WI序列后正确定性率达86.7%。结论:MRCP与True FISP序列均能很好判断有无胆管梗阻及梗阻部位,MRCP对胰胆管整体显示较好,不易漏诊小病变。但在定性方面,True FISP序列优于MRCP。单凭MRCP或True FISP不能区别炎症和肿瘤。Objective：To compare the value of MRCP and True FISP in diagnosising obstructive jaundice. Methods：MRCP and True FISP of 120 patients with suspected obstructive jundice were interpreted by two radiologists on a blinded basis, respectively. All the sequences were used to make diagnosis and the findings were compared with the results of ERCP, operation and pathology. Results： The sensibility and specificity of MRCP and True FISP in judging the existence and the level of obstructive jundice were high ; the accuracy of True FISP was higher than that of MRCP in judging the cause of obstruction（61.7% and 54.2% , respectively）. The accuracy of all the sequences in judging the cause of obstruction was 86.7%. Conclusion： Both two sequences demonstrated the existent and the level of obstruction well and MRCP is well in showing the whole outline of pancreaticobiliary. True FISP is more accuracy in judging the cause of obstruction. More sequences are needed to obtain more accurate diagnosis.
