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。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.
