摘要
目的:探讨MRI对肝性脑病的诊断价值。方法:对临床确诊的18例肝性脑病患者的MRI表现进行回顾性分析。结果:急性肝性脑病3例,2例MRIT1WI表现为两侧苍白球、中脑、垂体前叶对称性高信号,1例表现为轻度弥漫性脑水肿。慢性肝性脑病15例,T1WI表现为两侧苍白球(15/15)、中脑前份(14/15)和垂体前叶(10/15)对称性高信号,快速自旋回波序列TWI未显示异常信号。结论:MRI对肝性脑病有重要诊断价值。
Objective To evaluate the diagnostic value of MRI in hepatic encephalopathy. Methods The MRI findings of 18 patients with hepatic encephalopathy were retrospectively analyzed. Results There were 3 cases of acute hepatic encephalopathy. Bilateral globus pallids, midbrain and anterior pituitary lobes were showed symmetrical high signal intensity on T1WI in 2 cases of acute hepatic encephalopathy, the other cases demonstrated diffuse mild brain edema on MRI. There were 15 cases of chronic hepatic encephalopathy. Symmetrical high signal intensity on T1WI were found in bilateral globus pallidus （n=15）, the anterior portion of midbrain（n=14）and the anterior pituitary lobes（n= 10） ,but they were normal appearances on FSE T2WI. Conclusion MRI has an important value to the diagnosis of hepatic encephalopathy.
