     [摘 要] 目的:探讨多发性硬化(muliplle sclerosis,MS)的MRI特征表现及其诊断价值。方法:回顾分析31例临床诊断为MS患者的MRI检查资料。结果:31例共发现病灶184个,病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见,其次见于脊髓小脑、脑干及胼胝体,部分可见视神经受累,病灶呈卵圆形或圆形稍长T1、长T2信号,矢状位像见病灶与侧脑室垂直,急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论:在MRI图像上MS有特征性表现,MRI能反应MS病理变化,为临床诊断MS提供可靠依据。

    Abstract:Objective To study MRI diagnostic value on multiple sclerosis.Methods MRI examination data of 31 patients with multiple sclerosis were analysised retrospectively.Results Total 184 lesions were detectived in 31 patients.Most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.The shape of lesion can be circle or ellipse.The lesion showed as slightly long T1 and long T2 signal.The acute stage lesions can have enhancement.Conclusions MS have characteristic findings on MRI image.MRI can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis. ......
