摘要
目的：用ＭＲ显示胰、胆管扩张情况，并提出评价。材料与方法：检查５２例病人，其中胆道梗阻３５例，其它１７例。应用呼吸门控快速自旋回波，重Ｔ２加权成像技术及图像叠加后处理。其中２３例进行了手术治疗。结果：胆道梗阻病人均能显示梗阻部位及扩张的胆管，非梗阻病人可显示胆总管及部分左右肝管。结论：ＭＲＣＰ能显示胆管的狭窄部位、程度及扩张的胆管、胰管。与ＭＲＩ结合，能更准确地诊断梗阻部位及原因。与Ｂ超、ＣＴ及ＥＲＣＰ相比较，ＭＲＣＰ在诊断胆道梗阻的病因方面，具有独特的优越性。
Purpose::To evaluate magnetic resonance cholangiopancreatography (MRCP) in demonstrating the dilated pancres and bile ducts.Materials and methods:52 patients including 35 cases of bile ducts obstration and 17 cases of other causes,were examined by MRCP which was performed with a breath hold heavily T 2 weighted fast spin echo (FSE) seqence.The images were postprocessed on pile up.23 cases were operated in 52 patients.Results:The situation of biliary obstruction and dilated bile ducts were visualized in all patients with bile ducts obstruction.the novmal bile and hepatic ducts of left right sides were demostrated in the nonobstructive patients.Conclusion:MRCP could demostrate the site,extent of the biliary obstruction and the dilated cholangiopancres ducts.It could also show the situation and causes of obstruction more accurately when combined with MRI.In comparison with US,CT and ERCP,MRCP has some unique superior in diagnosing the cause of bile ducts obstruction.
