To investigate the relationship between cervical and thoracic sagittal alignment parameters measured by magnetic resonance imaging (MRI) and x-ray in patients with cervical spondylosisData from 120 symptomatic patients who presented with cervical spondylosis between April 2015 and January 2016 were retrospectively analyzed. Patients received both a cervical MRI and a cervical radiograph during a single visit. The thoracic inlet angle (TIA), T1 slope (T1S), neck tilt (NT), C2-C7 angle (C2-C7), and C2-C7 sagittal vertical axis (C2-7 SVA) were assessed. Pearson correlation coefficient, paired t test, and linear regression models were used to analyze parameters obtained by cervical MRI and radiography.The difference in mean thoracic inlet angle x-ray (TIAX) and thoracic inlet angle MRI (TIAM) (TIAM-TIAX) (0.72 ± 5.82°) was not significant (P > .05). There were significant differences in mean T1 slope x-ray (T1SX) and T1 slope MRI (T1SM) (T1SM-T1SX) (-2.55 ± 6.14°), mean neck tilt x-ray (NTX) and neck tilt MRI (NTM) (NTM-NTX) (3.26 ± 6.01°), mean C2-C7 angle x-ray (C2-7X) and C2-C7 angle MRI (C2-7 M) (C2-7M-C2-7X) (-3.57 ± 10.00°), and mean C2-C7 sagittal vertical axis X ray (C2-7 SVAX) and C2-C7 sagittal vertical axis MRI (C2-7 SVAM) (C2-7 SVAM-C2-7 SVAX) (-4.50 ± 1.26 mm) (all P ≤ .001). There were positive correlations between TIAM and TIAX (r = 0.807), T1SM and T1SX (r = 0.581), NTM and NTX (r = 0.759), cervical loidosis MRI and cervical loidosis x-ray (r = 0.666), and SVAM and SVAX (r = 0.226).MRI may be useful to evaluate thoracic inlet and sagittal alignment parameters in patients with cervical spondylosis. Patients with cervical spondylosis may have a relatively low capacity for compensation in the cervical region.
探讨磁共振成像（MRI）和X线测量的颈椎病患者颈椎和胸椎矢状位对线参数之间的关系
对2015年4月至2016年1月间120例有症状的颈椎病患者的数据进行回顾性分析。患者在单次就诊时接受了颈椎MRI和颈椎X线检查。评估了胸廓入口角（TIA）、T1斜率（T1S）、颈倾斜度（NT）、C2-C7角（C2-C7）和C2-C7矢状垂直轴（C2-7 SVA）。采用Pearson相关系数、配对t检验和线性回归模型分析颈椎MRI和X线检查获得的参数。
胸廓入口角X线（TIAX）和胸廓入口角MRI（TIAM）的差值（TIAM-TIAX）为（0.72±5.82°），差异无统计学意义（P>0.05）。T1斜率X线（T1SX）和T1斜率MRI（T1SM）的差值（T1SM-T1SX）为（-2.55±6.14°），颈倾斜度X线（NTX）和颈倾斜度MRI（NTM）的差值（NTM-NTX）为（3.26±6.01°），C2-C7角X线（C2-7X）和C2-C7角MRI（C2-7M）的差值（C2-7M-C2-7X）为（-3.57±10.00°），C2-C7矢状垂直轴X线（C2-7 SVAX）和C2-C7矢状垂直轴MRI（C2-7 SVAM）的差值（C2-7 SVAM-C2-7 SVAX）为（-4.50±1.26mm），差异均有统计学意义（均P≤0.001）。TIAM与TIAX之间（r=0.807）、T1SM与T1SX之间（r=0.581）、NTM与NTX之间（r=0.759）、颈椎病MRI与颈椎病X线之间（r=0.666）以及SVAM与SVAX之间（r=0.226）均呈正相关。
MRI可能有助于评估颈椎病患者的胸廓入口和矢状位对线参数。颈椎病患者在颈椎区域的代偿能力可能相对较低。
