摘　　要：目的探讨急性脊髓损伤的MRI表现及临床诊断价值。方法回顾分析60例急性脊髓损伤病人的MRI表现。结果按脊髓损伤程度分为脊髓震荡水肿、挫裂出血、受压扭曲及脊髓完全、不完全横断。脊髓震荡水肿的MRI表现为脊髓肿胀增粗,在T1WI加权像上呈稍低或等信号,在T2WI加权像上呈等或高信号;脊髓挫裂出血在T1WI加权像上呈等或高信号,在T2WI加权像上呈高信号;脊髓受压变形表现为脊髓曲度改变,有时呈"S"形扭曲;脊髓完全、不完全横断表现为正常脊髓连续信号完全中断或部分中断。结论MRI表现能反映脊髓损伤的形态和病理改变,可以指导治疗方案的选择,还有助于判断预后。Objective To evaluate manifestations of acute spinal cord injury （SPI） on MRI and its clinical value. Methods The MRI data in 60 cases of acute SPI were reviewed retrospectively. Results Based on the extent, the injury was classified as concussion and hydropsia, contusion and hemorrhage, compress and twist, complete or incomplete transsection of spinal cord. The manifestations on MRI were： for concussion and hydropsia, thickening of spinal cord, slight hypo- or isointense on T1WI, iso- or hyperimense on T2WI; for contusion and hemorrhage, iso- or hyperintense on T1WI, hyperintense on T2WI; for compression and twist, changed curvature of the spinal cord; for complete or incomplete transsection, interruption of the normal spinal cord. Conclusion MRI can reflect both pathology and morphology of the injured spinal cord, it is helpful in guiding clinical management and in predicting its prognosis.
