【摘要】　　目的探讨低场强mri在急性脊髓炎检查与诊断中的应用价值，为影像诊断提供更多的依据。方法对临床确诊的12例急性脊髓炎的mri和临床资料进行回顾分析。结果12例中病变累及颈髓者5例，颈髓至上段胸髓者1例，颈髓中、下段至上、中段胸髓者4例，下段胸髓受累2例；病变范围达4个以上椎体者10例；病变在t2wi上容易识别，均呈高或较高信号影，矢状位结合横轴位观察才能避免误判；5例脊髓轻度增粗，3例较明显增粗，4例脊髓形态改变不明显，脊髓形态改变在矢状位t1wi上显示清楚；3例行mri对比增强检查，其中1例呈中度条状强化，2例呈轻度斑片状强化，无占位效应。结论mri能直观地反映急性脊髓炎的病理改变，是该病的一种理想影像检查和诊断技术。
