Budd-Chiari综合征的MRI诊断

MRI Diagnosis of Budd-Chiari Syndrome

目的 探讨MRI对Budd Chiari综合征的诊断价值。材料与方法 分析 19例Budd Chiari综合征的MRI表现 ,并与超声和静脉造影进行对比。结果 肝脏增大 18例 (95 % ) ,肝尾叶增大 14例 (74% ) ,肝脏信号不均匀 14例 (74% ) ,7例 (37% )显示下腔静脉阻塞 ,4例 (2 1% )下腔静脉内见有血栓 ,肝静脉狭窄或阻塞 19例 (10 0 % ) ,17例 (89% )显示有肝内侧支血管 ,17例 (89% )显示肝外侧支血管 ,5例有副肝静脉 (2 6 % )。结论 MRI对于Budd Chiari综合征的诊断有较高的价值。

Objective To evaluate MRI in the diagnosis of Budd-Chiari syndrome.Materials and Methods MRI features of 19 cases with Budd-Chiari syndrome were analyzed. The findings were compared with that of sonography and venography.Results MRI demonstrated hepato- megaly in 18(95%) and enlarged caudate lobe in 14(74%) patients. Inhomogeneous signal intensity of hepatic parenchyma was seen in 14(74%) cases, obstructed inferior vena cava in 7(37%), thrombosis in inferior vena cava in 4(21%) and narrowed or obstructed hepatic veins in 19(100%). Intrahepatic collateral vessels, extrahepatic collateral vessels and accessory hepatic veins were displayed in 17(89%), 17(89%) and 5(26%) cases, respectively.Conclusion MRI has considerable value in the diagnosis of Budd-Chiari syndrome.
