该文对经2－7颈椎椎间盘与相应椎管的关系进行MRI研究.选取40例正常MRI扫描图像与80例临床有颈椎椎间盘症状的患者MRI扫描图像进行对照分析.认为椎管面积/椎间盘面积、椎管矢径/椎间盘矢径第二项指数的改变作为椎间盘退行性变的诊断指标是可靠的.“,”MRI studies were carried out on the relation between cervical interverbral disc and verbral canal. 40 normal MRI scanning images were analyzed and 80 typicaI cases with cervical intervertebral disc disease were randomly selected. The index number changes of verterbral canal area to interverbral disc area ratio, verterbral canal anteroposterior diameter to interverbral disc anteropopsterior diameter ratio serve as an intervaerbral disc disease-diagnosis sbodard. All this had anatomic and diagnostic imqgeologic foundation and was denpendable.
