脊髓多发性硬化的MRI诊断分析

The MRI value in diagnosing spinal cord multiple sclerosis

摘要: 目的:探讨脊髓多发性硬化的MRI表现及其诊断。方法:分析9例脊髓多发性硬化病变的部位、范围、病变处脊髓形态、MRI信号及强化程度。结果:发生在颈髓4例,颈胸髓同时受累3例,单纯胸髓受累2例。病变呈条带状、斑点状,T1WI呈低或等信号,T1WI呈高信号,T2WI轴位上病变以点片状高信号为主,增强后病灶强化或不强化。结论:MRI有助于脊髓多发性硬化与其他脊髓内病变的鉴别诊断。

Abstract: Objective:To explore magnetic resonance imaging(MRI) appearance of spinal cord multiple sclerosis and its diagnostic value.Methods:The location,extent,morphology,MRI signal and enhancement degree of spinal cord multiple sclerosis were analyzed in 9 cases.Results:Cervical,cervical and thoracic,and thoracic spinal cord were involved in 4,3 and 2 cases,respectively.The lesions were patches and long ribbon in shape.Low or iso-signal intensity on T1WI and high-signal intensity on T1WI were found.Point flake high lesions signal on T2WI were observed,The lesion was enhancement or no enhancement by enhanced MRI scan.Conclusions:MRI can help the differential diagnosis with other intraspinal diseases.
