目的提高对脊髓型多发性硬化 (MS)的临床与MRI表现的认识。方法回顾性分析 18例临床确诊的脊髓型MS的临床与MRI表现特征。结果 18例MS在矢状位MRI上均发现与脊髓长轴平行的T1WI略低信号 ,在T2 WI为高信号 ,病变局部脊髓正常或轻度肿胀 ,横断面上病变位于脊髓周边 ,面积小于脊髓断面 1/ 2 ,病变在急性或活动期有强化。结论MRI能够显示脊髓型MS特征表现可做为确诊脊髓型MS的首选检查方法 Objective To improve the clinical and MRI findings of spinal cord multiple sclerosis (MS). Methods The clinical and MRI findings of 18 clinically diagnosed spinal cord MS patients were retrospectively analyzed. Results In 18 cases of MS, MRI showed a slightly lower signal of T1WI parallel to the long axis of the spinal cord, a high signal at T2 WI, normal or slight swelling of the local spinal cord in the lesion, lesion on the periphery of the spinal cord in cross section, Section 1/2, lesions in the acute or active period of strengthening. Conclusion MRI can show the performance of spinal cord MS can be used as the first choice for the diagnosis of spinal cord MS
