摘　　要：目的:探讨磁共振成像(MRI)对亚急性坏死性脑脊髓病的诊断价值。方法:收集我院确诊为亚急性坏死性脑脊髓病患者6例,回顾性分析其MRI表现。结果:6例患者均出现双侧豆状核对称性异常信号,T1WI呈低信号,T2WI呈高信号,T2-FLAIR呈混杂信号,无占位效应,增强扫描病灶无强化。结论:亚急性坏死性脑脊髓病最常累及双侧豆状核,其MRI表现具有特征性,结合临床容易诊断。Objective：To evaluate the value of MRI in the diagnosis of sub-acute necrotizing encephalomyelopathy.Methods：6 patients identified clinically as sub-acute necrotizing encephalomyelopathy were collected in our study,and their MRI data were analyzed retrospectively.Results：Symmetrical abnormal signal inensity in bilateral lentiform nuclei was found in all 6 cases.The lesion demonstrated as hypointensity on T1WI and hyperintensity on T2WI,and mixed signal intensity on T2-FLAIR.The lesion had no mass effect and was not enhanced after contrast administration.Conclusion：Bilateral lentiform nuclei are the most commonly involved sites in sub-acute necrotizing encephalomyelopathy.Its MRI features are characteristic.When combined with clinical information,it can be diagnosed easily.
