摘　　要：目的分析布-加氏综合征的MR、ICT的表现,进一步提高该病的诊断率。方法对经血管造影证实的15例Budd-Chiari综合征的MR、ICT表现进行回顾性分析。结果15例MRI和CT诊断均正确,2例伴多发再生结节定性诊断正确。Budd-Chiari综合征MR、CT有下列征象:(1)下腔静脉和/或肝静脉狭窄或闭塞(15例);(2)肝实质淤血肿胀伴异常密度或信号灶(12例),延迟扫描无明显强化(7例),部分可见肝实质强化逐渐均匀(5例);(3)迂曲增粗及逗点状侧枝循环(10例);(4)无肝炎背景的肝硬化、腹水,伴或不伴脾轻度肿大(4例),伴侧枝循环形成(15例);(5)多发再生结节(2例)。结论MRI、CT对Budd-Chiari综合征的诊断具有重要价值。Objective To analyse MR imaging and CT findings of Budd - Chiari syndrome,so as to improve the diagnosis of it. Methods MR imaging and CT findings of 15 cases of Budd - Chiari syndrome were analysed retrospectively. Results All 15 cases were correctly diagnosed by MRI and CT,and 2 cases accompanied multiple regenerative nodi were also diagnosed correctly. The signs of Budd - Chiari syndrome on CT and MRI included： （ 1 ） inferior vena and/or hepatic vein stenosis or occlusion （ 15 cases ） ; （ 2 ） liver parenchyma congestion with abnormal signal intensity or density （ 12 cases ）, no enhancement （ 7cases ） or gradually enhancement （ 5 cases ） ; （ 3 ） circuity thickening or comma sign of collateral circulation （ 10 cases ） ; （4 ） liver cirrhosis without hepatitis background, ascitic fluid,with or without spleen swell lightly（ 4 cases） , collateral circulation formed（ 15 cases） ;（ 5） multiple regenerative nodules（ 2 cases）. Conclusion CT and M RI have important value in diagnosing Budd - Chari syndrome.
