摘　　要：目的:探讨3.0T磁共振对肝静脉型布-加氏综合征(HVBCS)的诊断价值。方法:57例HVBCS患者均行3.0T磁共振平扫及三维对比增强MR血管成像(3D CE MRA)检查,观察肝静脉(HV)改变、侧枝循环的建立及肝实质改变情况。全部患者均行HV造影证实,分析磁共振结果。结果:HV:共显示126支,其中HV广泛阻塞21支;开口阻塞93支;以上HV阻塞病例中有血栓形成6支;正常HV12支。以血管造影为金标准,磁共振显示HV灵敏度为91.3%,特异度为100%。副肝静脉(AHV):显示38支,其中17支开口狭窄。侧枝循环:肝内侧枝循环形成53例,4例无肝内侧枝循环;全部病例均有肝实质改变。结论:3.0T磁共振能准确显示HV病变,肝内侧枝循环,肝实质改变,在诊断HVBCS中有重要价值。Objective:To study the value of 3.0 T MR imaging in diagnosing on Budd-Chiari syndrome with hepatic vein occlusion(HVBCS).Methods:3.0 T SE sequence T1WI,T2WI and three-dimensional contrast-enhanced magnetice angiography were performed on 57 patients with HVBCS.Observe the condition of occlusion of HV,the presence of intrahepatic collaterals and liver parenchymal abnormalities.All the vein of the 57 patients were certified by DSA.Analyze the image of MRI.Results:A total of 126 hepatic veins were presented.Includ 21 hepatic veins extensively occluded,93 hepatic veins occluded at outlet,6 hepatic veins of above with thrombosis in it,12 hepatic veins is normal.The sensitivity and the specificity of MRI to present HV were 91.3% and 100% respectively.38 assessory hepatic veins were presented,and 17 assessory hepatic veins stenosis at outlet.53 cases presented intrahepatic collaterals,and 4 cases without it.All the cases presented liver parenchymal abnormalities.Conclusion:3.0 T MRI can accurately present the occlusion of HV,intrahepatic collaterals and liver parenchymal abnormalities,and have significant value in diagnosis of HVBCS.
