摘要
目的:了解多发性硬化(MultipleSclerosis,MS)临床和常规性磁共振(MRI)以及磁共振弥散成像(DWI)的相关性。方法:分析40例确诊MS的临床表现、临床定位及核磁共振检查结果。结果:根据40例MS临床表现,病灶定位有73个,其中大脑29个,小脑5个,脑干11个,视神经16个,脊髓12个。40例MS常规MRI扫描在T2WI像上呈规则或不规则高信号占40/40,T1WI表现为低信号者占13/40,10例同时行DWI均可见明显的轻度高信号。MR发现的病灶总数为156个,其中分布在大脑半球双侧白质区94个,底节区17个,丘脑5个,脑干14个,小脑16个,脊髓10个。结论:MRI,特别是DWI有助于早期发现MS临床病灶。
Objective: To investigate the pertinency between the clinical characteristics in patients with Multiple Sclerosis and their characteristics of magnetic resonance imaging (MRI) or diffusion weighted imaging (DWI). Method: To analyse the clinical features, clinical orientations and their characteristics of magnetic resonance imaging (MRI) or diffusion weighted imaging (DWI) in 40 cases with Multiple Sclerosis.Result: According to the clinical features, there were 73 clinical orientations in all, of them 29 orientations in cerebrum, 5 orientations in cerebellum, 11 orientations in brainstem, 16 orientations in optic nerve and 12 orientations in spinal cord. 40 cases where checked-up by MRI, 10 of them checked-up by DWI. 156 lesions were demonstrated by MRI and DWI, of them 94 were found in white matter, 17 lesions in basal gangli area, 5 lesions in thalamus, 14 lesions in brainstem, 16 lesions in cerebellum and 10 lesions in spinal cord. Conclusion: MRI, especially the DWI, may help to find those lesions without clinical features of Multiple Sclerosis early.
