目的探讨磁共振(MRI)在脊髓亚急性联合变性诊断中的应用价值。方法回顾性分析10例经临床证实的脊髓亚急性联合变性患者的MRI表现，总结其影像特征。结果脊髓亚急性联合变性多为中老年男性，多累及颈胸段脊髓的后索及侧索，于T2WI序列表现出斑片状高信号无明显强化。临床上多表现维生素B12缺乏及不同程度贫血。结论结合临床与MRI表现，可对脊髓亚急性联合变性做出正确诊断。%Objective To explore magnetic resonance (MRI) in the diagnosis of subacute combined degeneration of spinal cord.Methods A retrospective analysis of 10 cases of clinical y confirmed patients with subacute combined degeneration of the spinal cord MRI performance,summarizes its image characteristics.Results Subacute combined degeneration of spinal cord for older men,lesions involving the neck line after thoracic segment of the spinal cord and Lou,patchy showed high signal on T2WI sequences,no obvious reinforcement.Vitamin B12 deficiency and clinical presentations more dif erent degree of anemia. Conclusion Combined with clinical and MRI performance,can make a correct diagnosis of subacute combined degeneration of spinal cord.
