Budd-Chiari综合征的MRI

Budd-Chiari Syndrome:MRI Findings

目的：探讨Ｂｕｄｄ－Ｃｈｉａｒｉ综合征的ＭＲＩ和ＭＲＡ表现及其诊断价值。材料和方法：回顾性分析５例经腔静脉造影证实的Ｂｕｄｄ－Ｃｈｉａｒｉ综合征的ＭＲＩ和ＭＲＡ表现，并与腔静脉造影进行比较。结果：ＭＲＩ和ＭＲＡ表现如下：１、肝肿大，３例慢性者尾叶增大；２、肝静脉未显示，肝内血管呈逗点状；３、下腔静脉狭窄、阻塞和狭窄阻塞后扩张及血流信号异常，与腔静脉造影比较，ＭＲＩ和ＭＲＡ显示狭窄和阻塞的形态不够确切；４、肝外侧枝血管形成。结论：ＭＲＩ对Ｂｕｄｄ－Ｃｈｉａｒｉ综合征具有特征性的诊断价值，但不能取代腔静脉造影。

Purpose:To investigate the features and usefulness of MRI and MRA in Budd-Chiari Syndrome(BCS).Materials and Methods:The records of 5 patients with proved vena cava angiography were reviewed and analysed retrospectively together with MR manifestations and diagnostic usefulness.Results:MRI and MRA findings cannot demonstrate left,middle and right hepatic veins,but can show the formation of intrahepatic collateral circulation,stenosis,obstruction,dilation and signal-intensity abnormalities of inferior vena cava.Conclusion:Although MRI and MRA features of BCS were proved to be the reliable diagnostic method but can not replace the vena caca angiography.
