低场MRCP在梗阻性黄疸中的应用及B超、CT的对照分析

目的　探讨低场MRCP在梗阻性黄疸中的诊断价值。方法　收集经临床证实的梗阻性黄疸患者 55例,同时与所做CT和B超结果对照分析。结果　55例梗阻性黄疸,其中胆管结石 30例、肿瘤 21例,其他 4例;MRCP显示胆道梗阻的部位准确性达 100%,确定梗阻病因的准确性为 81. 8%。结论　低场MRCP可对胆管梗阻性疾病准确定位, 3D-FSEMRCP联合MR常规T1WI、T2WI断层扫描,对梗阻性黄疸病变的诊断具有很高的敏感性、准确性。

The Application of the Low Field MRCP in Obstructive Jaundice and the Comparative Analysis with US and CT

Objective To evaluate the diagnostic value of the low field MRCP in obstructive jaundice by comparing its result with that of US and CT. Methods 55 cases of obstruction jaundice patients proved by clinical diagnosis were studied and compared the collected original diagnosis results by low filde MRCP with US and CT.Results Of 55 cases of obstructive jaundice, 30 were cholelithiasis ,21 were tumors and 4 belonged to the other type. The accuracy of MRCP for defining the site of obstruction was 100%. The accuracy for identifying the cause of obstruction was 81.8%.Conclusion The low filde MRCP can accurately define the obstructive site in biliary obstructive disease .When used together with 2D single-shot breath-hold MRCP , T 2WI, T 1WI and 3D-FSE MRCP shows high accuracy and sensitivity in diagnosing obstructive jaundice.
