摘　　要：目的:探讨脑内多发性硬化(MS)的核磁共振(MRI)诊断价值。方法:回顾性分析48例经临床确诊为MS患者的MRI表现及相关资料。48例均行MRI常规平扫,46例加做增强扫描。结果:(1)病灶多发,主要分布于侧脑室周围及额、颞、顶、枕叶皮层下白质区,部分累及胼胝体、小脑、脑干、丘脑、基底节及大脑皮质;双侧侧脑室旁可见"垂直脱髓鞘征";(2)病灶主要以长和较长T2、略长和等T1信号为主;(3)增强扫描显示强化与不强化病灶同时存在,强化病灶呈点状、斑片及环形;少数急性起病病例病灶呈较均匀一致的强化。结论:MRI是临床诊断MS的敏感、直观、最有价值的检查手段。Objective： To discuss cerebral MRI features of the brain with Multiple sclerosis（MS）.Methods： Retrospective analysis MRI manifestations and related material of 48 cases of MS diagnosed by clinical.48 cases were plain and 46 cases were enhanced.Results： Multiple lesions and mainly distributed in the lateral ventricle and the frontal and temporal around,top,occipital lobe subcortical white matter area,Part of the lesions involving the corpus callosum,cerebellum,and brain stem,thalamus,basal ganglia,and cerebral cortex;Pairs of side ventricles of the brain side visible ＂vertical demyelination sign＂;Most of the lesions were long T2,slightly long and medium T1.Enhancement scan showed： intensified and stable and intensified lesions look spotted,flake,or ring-shaped.A few cases of acute onset lesions are more uniform reinforcement.Conclusions： MRI is a sensitive,intuitive,the most valuable inspection method of clinical diagnosis of MS.
