      다국어 초록 (Multilingual Abstract)

      Objective: Recently, many studies have reported that cervical alignment is related to clinicaloutcomes. However, poor visibility of anatomical structures during X-ray (XR) imaging limitsaccurate measurements. In supine magnetic resonance (MR) imaging, the boundary of theanatomical structure is clear, but the correlation to XR images taken in a standing positionis problematic. In this study, we evaluated the agreement of sagittal alignment parametersbetween MR and XR measurements.
      Methods: We retrospectively reviewed 268 patients. Cervical sagittal parameters weremeasured using XR and MR images, and their relationships were evaluated using Pearson'scorrelation, paired t-tests, and 2-way random, single score intraclass correlation coefcient(ICCs) (2,1). Using simple linear regression analysis, MR results were converted to theexpected value (MR-E). The subsequent comparison of MR-Es with XRs was used to examinewhether MR-Es could replace XRs when the measurement difference was less than 2 mm or 2°.
      Results: The correlation between the MR and XR measurements was high, but ICCs showedlow reliability. All parameters were signifcantly different between XR and MR measurementsin paired t-tests. Converting the MR values eliminated the t-test differences between MR-Esand XRs, but did not affect correlations and ICCs. The replacement ratio included the Cobbangle: 20.3%, T1: 27.1%, the sagittal vertical axis: 17.6%, C1–2: 29.7%, and C2: 16.0%.
      Conclusion: These results indicate that supine MR measurements could not replace uprightXR measurements
