目的 分析研究成人颈椎X线与 CT重建图像中矢状面参数的差异及相关 性。方法 收集我院2013年1月至2015年12 月间就诊的58例患者为研究对象，所有 患者均在同期行颈椎侧位X线及颈椎CT检 查。测量参数包括C2-7 Cobb角、C2-7 Gore 角、CCI。结果 对不同检查方法间参数 比较及相关性分析，结果显示，颈椎X线 测量的Cobb角、Gore角均大于CT检查结 果，差异具有统计学意义(P<0.05)；两 种方式的CCI结果相当，组间比较未见显 著性差异(P>0.05); 两种检查方法Cobb 角、Gore角及CCI间的相关系数分别为 0.013、0.009、0.015，差异具有显著性 (P<0.05)。结论 颈椎CT重建图像中矢状 面参数与常规X线比较具有显著性差异， 但两种测量结果间存在较强的相关性，颈 椎CT可做为疾病诊断和术前评估的重要方 式。

Objective To study the difference and correlation between sagittal plane parameters of cervical X-ray and CT reconstruction images of adult cervical spine. Methods 58 patients who were treated in our hospital from January 2013 to December 2015 were studied. All patients were examined by X-ray and CT examination of the cervical lateral position. Measurement parameters including Cobb C2-7 angle, Gore C2-7 angle, CCI. Results of different methods of checking parameter comparison and correlation analysis, results showed that, cervical spine X-ray measurement of the Cobb angle, Gore angle were greater than CT examination results, the difference has statistical significance (P<0.05), two ways of CCI results quite, between groups is not significant difference (P>0.05), the correlation coefficient between the two kinds of inspection methods of Cobb angle, Gore angle and CCI respectively 0.013 0.009, 0.015, the difference is significant (P<0.05). Conclusion cervical CT image reconstruction sagittal parameters and conventional radiography in comparison with significant difference, but between the two measurement results exist strong correlation, cervical spine CT to do for disease diagnosis and preoperative evaluation of important ways
