摘　　要：目的分析慢性酒精中毒性脑病的MRI表现。方法搜集18例经临床诊断慢性酒精中毒性脑病患者,行MRT1WI、T2WI和FLAIR检查,分析其MRI表现。结果18例中,12例表现为脑白质稀疏症,4例表现为胼胝体变性,2例合并桥臂异常信号灶,MRI上病变主要呈T1WI稍低、T2WI和FLAIR序列高信号。结论MRI能清楚显示慢性酒精中毒性脑病的病变范围,有助于临床诊断及预后疗效观察,是较可靠的影像学检查方法。Objective To analyze the MRI appearance of chronic alcoholic toxic encephalopathy. Methods TIWI, T2WI and FLAIR of MRI were performed in 18 patients with chronic alcoholic toxic encephalopathy confirmed clinically. MR appearance were analyzed. Results Leuko-araiosis （n= 12） , marchiafava-Bignami disease （n=4）, and parabrachial disease （n =2） were found in the 18 cases, with pieces of hypointensity on TlWI, hyperintensity on T2WI and FLAIR. Conclusion MRI can demonstrate optimally the invading extent and provide more accurate information for clinical staging. MR imaging is the reliable method in diagnosis of chronic alcoholic toxic encephalopathy.
