| 摘 要： | 目的探讨各种急性中毒性脑病的MRI表现。资料与方法分析11例急性中毒性脑病患者的MRI表现,其中药物中毒6例,一氧化碳(CO)中毒3例,酒精中毒2例。结果所有急性中毒性脑病患者脑部MRI表现均为对称性信号异常,呈长T1、长T2改变,扩散加权成像(DWI)为明显高信号。3例药物中毒者MRI表现为皮质区、白质区和基底节区广泛性对称性受累,另3例药物中毒者表现为单纯尾状核和壳核对称性受累;3例CO中毒者表现为尾状核和壳核对称性受累;2例酒精中毒者病变仅累及白质区域(半卵圆中心和胼胝体),而不累及皮层区和基底节神经核团。结论 MRI有助于急性中毒性脑病的诊断,不同原因的急性中毒性脑病MRI表现有一定的特征。
