目的:评价磁共振成像(MRI)在布-加综合征(BCS)诊断中的应用价值。方法:收集2003年11月至2011年5月大连医科大学附属第二医院收治的经DSA确诊的布-加综合征患者16例作为研究对象,观察MRI检查结果。结果:常规MR检查示14例肝脏体积增大、2例肝脏体积缩小,形态不规则;12例伴有脾脏肿大:13例伴有腹水。3D-DCE-MRA检查示肝静脉和/或肝段下腔静脉血管腔内瓣膜10例、血管腔内血栓3例、肝静脉和/或肝段下腔静脉外压性狭窄3例。侧支循环形成14例,其中单纯发生于肝内4例、单纯肝外6例,两者兼有4例,侧支循环血管共33处。MR诊断与DSA确诊结果一致。结论:MRI对布-加综合征的诊断准确、全面,具有重要应用价值。
Objective: To evaluate the value of magnetic resonance imaging (MRI) in the diagnosis of Budd-Chiari syndrome (BCS). Methods: Totally 16 DSA-diagnosed patients with Budd-Chiari syndrome who were admitted to the Second Affiliated Hospital of Dalian Medical University from November 2003 to May 2011 were selected as the research object and MRI findings were observed. Results: The routine MR examination showed that the volume of liver increased in 14 cases, the size of liver in 2 cases decreased and the shape was irregular. The spleen enlargement was found in 12 cases: 13 cases had ascites. 3D-DCE-MRA showed 10 cases of endovascular valves in the hepatic vein and / or inferior vena cava, 3 cases of intravascular thrombus, 3 cases of hepatic vein and / or extrahepatic venous compression of hepatic segment. Collateral circulation formed in 14 cases, which occurred in 4 cases of simple liver, simple extrahepatic 6 cases, both in both 4 cases, a total of 33 collateral circulation vessels. MR diagnosis consistent with the results of DSA. Conclusion: MRI diagnosis of Budd-Chiari syndrome is accurate, comprehensive and has important application value.
