摘　　要：目的:探讨MRI对平山病的诊断价值。材料与方法:分析经临床诊断为平山病的10例患者的颈部MRI表现。结果:MRI自然位6例颈椎生理曲度前凸消失、7例低位颈髓萎缩、2例T2WI颈髓内条状异常高信号、9例颈髓不对称性扁平及LOA(loss of attachment)现象;过屈位8例出现背侧硬膜囊前移、9例硬膜外间隙增宽、新月形T2高信号影、4例迂曲血管流空信号。结论:颈部MRI自然位及过屈位能发现平山病异常特征征象,对平山病的诊断具有重要价值。Purpose： To study the diagnostic value of MRI in Hirayama Disease. Materials and Methods： The MRI data of 10 clinically proven Hirayama patients were analyzed. Result： Neutral position MRI showed loss of cervical lordosis in 6 eases, localized lower cervical cord atrophy in 7 cases, iutramedullary hyperintensity of T2 WI in 2 cases, asymmetric cord flattening and loss of attachment in 9 cases. Flexion position MRI showed anterior displacement of dorsal dura in 8 eases, the widened epidural space and posterior epidural crescent shaped component of T2WI in 9 cases, epidural flow voids in 4 cases. Conclusion： MRI ean show abnormal characteristic manifestations of the Hirayama disease and have the important value in diagnosis of the Hirayama disease.
