摘要(Abstract)：

目的比较颈椎屈曲不同角度平山病患者的MRI表现,探讨颈椎屈曲角度的调节对平山病的MRI诊断价值。材料与方法 19例临床确诊为平山病的患者,使用自行研发的辅助诊断设备行不同屈曲位颈椎MRI检查,屈曲角度包括:0°(中立位)、25°、30°、35°、40°,观察不同屈曲位MRI三个典型征象显示情况:脊髓萎缩、背侧硬脊膜前移、硬膜外间隙增宽。测量不同屈曲角度硬膜外间隙最大矢状径(d)及同层面椎管矢状径(D),并计算d/D。结果平山病患者MRI特异性征象在屈曲角度25°及以上与屈曲0°存在差异(P=0.00),d/D平均值随屈曲角度增加在一定范围内增加,35°时最大。结论屈曲位MRI检查可以影响颈椎背侧硬脊膜前移、脊髓萎缩、硬膜外间隙增宽等征象。
