脊髓多发性硬化的MRI征象分析

目的:探讨脊髓多发性硬化的MRI表现特征,提高诊断水平。方法:18例脊髓多发性硬化行脊髓和/或头部MRI检查,对其征象进行分析。结果:18例脊髓多发性硬化主要发生在颈髓8例,占44.4%,颈胸髓同时受累7例,占38.9%,单纯胸髓受累2例,占11.1%,全部脊髓受累1例,占5.6%。病变呈条带状、斑点状,T1WI呈低或等信号,T2WI呈高信号,T2WI轴位上病变呈点片状高信号为主,增强后病灶强化或不强化。结论:脊髓多发性硬化有其特征性MRI表现,MRI是目前诊断脊髓多发性硬化最敏感的影像学方法。

Analysis of MRI Manifestations in Multiple Sclerosis Spinal Cord

Objective To investigate the characteristic MRI appearances of multiple sclerosis(MS) in the spinal cord.Methods 18 cases diagnosed clinically as MS were examined by MR.All image appearances were analyzed.Results Cervical spinal cord was involved in 8 cases(44.4%);cervical and thoracic spinal cord simultaneously in 7 cases (38.9%),thoracic spinal cord in 2 cases (11.1%) and whole spinal cord in 1 case (5.6%).The lesions were manifested as patches in shape and long ribbon shape with low or iso-signal intensity on T_1WI and high-signal intensity on T_2WI,enhanced MRI scan was enhanced or without enhancement.Conclusion MS of spinal cord has characteristic feature on MRI and MR is the most important and sensitive method for diagnosing spinal cord MS.
