ABSTRACT
<p><b>OBJECTIVE</b>To assess the quality of whole spine images obtained by DR and magnetic resonance imaging (MRI) and analyze the whole spinal imaging sagittal parameters for standing DR and supine MRI.</p><p><b>METHODS</b>Sixty-one patients aged 49.9∓17.6 years with degenerative spinal disease underwent both standing DR and supine MRI of the whole spine from November, 2010 to March, 2016. The image quality was retrospectively reviewed, and the cervical lordosis (CL), thoracic kyphosis (TK), lumbar lordosis (LL), sacral slope (SS), and sagittal vertical axis (SVA) were measured on the whole spinal lateral DR and middle sagittal MR images.</p><p><b>RESULTS</b>Both the DR and MR whole spine images had a high quality (100%). The CL, TK, LL, SS, and SVA measured were 28.37mnplus;10.91 °, 29.98mnplus;8.96 °, 45.61mnplus;12.46 °, 34.38mnplus;9.05 °, and 17.20mnplus;26.39 mm on DR images and were 24.34mnplus;9.01 °, 21.22mnplus;8.13 °, 41.45mnplus;12.17 °, 37.45mnplus;8.19 °, and 36.51mnplus;12.44mm on MR images, respectively, showing significant differences in the measurements between the two modalities (P=0.000, 0.000, 0.000, 0.001, and 0.007, respectively). The correlation coefficient between DR and MR images for CL, TK, LL, SS, and SVA were 0.69, 0.68, 0.72, 0.51, and 0.27 (P=0.000, 0.000, 0.000, 0.000, and 0.034, respectively).</p><p><b>CONCLUSION</b>Both standing DR and supine MR whole spine imaging can provide high-quality images. The CL, TK, LL, SS, and SVA measured on supine MR whole spine images are correlated with those on standing DR images but differ obviously. Supine MR imaging can not substitute standing DR examinations, and comprehensive assessment of degenerative spinal disease needs the combination of the two imaging techniques.</p>
