MRI联合多层螺旋CT在肝性脑病诊断中的价值

Exploration of MRI and MSCT Diagnostic Value in Hepatic Encephalopathy

目的探讨MRI联合多层螺旋CT对肝性脑病的诊断价值。方法对临床确诊的15例肝性脑病患者的MRI及多层螺旋CT影像资料进行回顾性分析。结果急性肝性脑病3例,2例MRI T1WI表现为双侧基底节苍白球区、中脑腹侧高信号,T2WI未显示异常信号,螺旋CT呈等密度改变,1例MRI及CT表现为弥漫性脑水肿改变。慢性肝性脑病12例,T1WI像显示双侧基底节苍白球区高信号10例、中脑腹侧高信号6例,垂体前叶高信号4例,T2WI未显示异常信号,MRI及CT显示脑萎缩改变8例。结论MRI联合螺旋CT对肝性脑病诊断具有重要临床价值。

[Abstarct]Objective To evaluate the diagnostic value of MRI and muti-slice CT in hepatic encephalopathy.Methods The MRI ang MSCT findings of 15 patients with hepatic encephalopathy were retrospectively analyzed.Results There were 3 cases of acute hepatic encephalopathy. Bilateral basal ganglia area globus pallids, midbrain and anteriorpituitary lobes were showed symmetrical high signal intensity on T1WI and normal appearances on T2WI and equal density on MSCT in 2 cases of acute hepatic encephalopathy. The other cases demonstrated diffuse brain edema on MRI and MSCT. There were 12 cases of chronic hepatic encephalopathy. 10 cases high signal intensity on T1WI were found in bilateral basal ganglia area globus pallid, 9 cases high signal intensity on T1WI were found in the midbrain and 4 cases high signal intensity on T1WI were found in the anterior pituitary lobes. They were normal appearances on T2WI. There were 8 cases of brain atrophy on MRI and MSCT.Conclusion MRI and MSCT has an important value to the diagnosis of hepatic encephalopathy.
