应用X线平片、CT及MRI在颈椎病诊断中的对比研究

目的：探讨X线平片、CT、MRI检查在颈椎病诊断中的作用。方法选取2011年9月～2013年5月我院收治的颈椎病患者57例，所有患者皆进行X线平片、CT、MRI检查。结果对颈椎病的原因分析，MRI对钩突增生、颈椎曲度异常、椎间隙狭窄的诊断率高，显著高于其他两种方法，差异有统计学意义（P＜0.05）。而CT对钩突增生、小关节突增生、椎体后缘骨赘形成、骨性椎管狭窄的诊断率高于X线平片（P＜0.05）。而对颈椎曲度异常、椎间隙狭窄诊断率低于X线平片（P＜0.05）。X线平片可以观察到颈椎双边征及椎间孔狭窄。而MRI则对纤维性椎管狭窄，伴脊髓水肿、变性，寰枢椎半脱位有独特的征象。结论综合X线平片、CT、MRI可提高颈椎病的早期诊断和定性诊断的水平。

Comparative study on the application of X-ray,CT and MRI in the diagnosis of cervical spondylosis

Objective To explore the effect of X-ray, CT and MRI in the diagnosis of cervical spondylosis. Methods 57 patients with cervical spondylosis were all collected from 2011 September to 2013 May in our hospital, who were examined with X-ray, CT and MRI examination. Results The analysis of causes for cervical spondylosis showed that the diagnosis rate of MRI on uncinate hyperplasia, cervical curvature abnormality, intervertebral space stenosisrate was significantly higher than the other two methods, the difference was statistically significan（P〈 0.05）. While the diagnosis rate of CT on uncinate hyperplasia, facet hypertrophy, osteophyte formation, bony canalstenosis was higher than X-ray（P 〈 0.05）. The diagnosis rate of CT on abnormal cervical curvature and intervertebral space stenosisrate was lower than X-ray（P 〈 0.05）. X-ray could observe bilateralsyndrome and cervical intervertebral foramen stenosis, while the MRI had unique features on fibrous canal stenosis with spinal cord edema, degeneration, atlantoaxial subluxation. Conclusion Integrated X-ray, CT and MRI can improve the early diagnosis and qualitative diagnosis level of cervical spondylosis.
