| 摘 要： | 目的探讨MRI在脊髓亚急性联合变性诊断中的价值。方法回顾分析6例脊髓亚急性联合变性患者的MRI平扫及Gd-DTPA增强扫描资料。结果脊髓亚急性联合变性多见于中老年人,男性多于女性,病变多累及颈胸段脊髓的后索、侧索,并可不同程度累及脑白质、视神经和周围神经,表现为弥散而不均匀的白质变性,在MRIT1WI序列病变信号变化不明显,与正常脊髓相似,T2WI序列上呈条状或斑片状的高信号,边界欠清晰;Gd-DTPA增强扫描检查病变强化不明显。结论 MRI因其多方位、多序列成像等优点,对脊髓亚急性联合变性的诊断具有重要的价值,为首选影像学检查方法 。

| Abstract: | Objective To evaluate the value of MRI in diagnosis of the SCD.Methods 6 patients with SCD which has been proved by diagnosis of operation, biopsy of pathology or clinic have been examined by MRI and Gd-DTPA enhanced. Results Most of SCD is in elderly, and male are more than female. The pathological changes involves in neck chest more segment of the dorsalis and funiculus lateralis of the spinal cord, and it can involve in the brain white quality, optic and peripheral nerve in different degree. Conclusion Because MRI can scan in many ways and sequences, it has important value for the SCD.MRI is the preferred method. |
