MRI诊断颈椎病的影像学分析

Imaging analysis of MRI diagnosis in cervical spondylosis

目的：观察颈椎病的MRI表现。材料与方法：搜集1995年3月—1996年3月期间经MRI诊断为颈椎病的病例151例，男95例，女56例，平均年龄49．5岁。均应用西德SINMENS公司MagnetomImpact1．0T超导型磁共振扫描机检查，均行矢状面及横断面颈椎平扫。结果：发现颈椎、椎间盘、颈髓及韧带均有改变，其中，颈椎生理曲度改变61例，椎体骨质增生83例316个；椎间盘退变151例378个；颈髓变性23例。结论：笔者对151例颈椎病的MRI表现进行了观察分析，认为其MRI表现特征如下：1．颈椎：生理曲度可反弓、强直或保持正常；椎体骨质增生等退行性改变；2．单／多个椎间盘膨出、突（脱）出，髓核可脱水变性；3．预髓亦可出现受压变形、缺血、水肿、变性，甚至形成软化灶。

Purpose:To study the MR imaging of cervical spondylosis. Materials and methods:To select 151 patients diagnosed cervical spondylosis between 1995. 3 to 1996. 3, 95 male and56 female. The average age of the patients was 49. 5. All patients were undergone MR examination and used transverse and sagittal scanning. Results: The authors discovered that vertebrae,disc,cervical cord and ligament were changed, 61 cases physiologic curve changed , 316 vertebraeof 83 cases hyperostosis; 378 discs of 151 cases and 23 cases cervical cord degeneration. Conclusion : The authors studied MR imaging of cervical spondylosis,and discovered the characters as:1. posterior arch of cervical vertebrae or no; and hyperostosis ; 2. single/multi disc herniation anddegeneration; 3. cervical cord might be chronic spinal compression,ischemia, edema,degenerationand softening.
