- aggregation abstract "Objective : To evaluate agreement and repeatability of vertebral column measurements using computed tomography (CT) and magnetic resonance imaging (MRI). Study Design : Retrospective observational study. Animals : Dogs (n=18) with disc associated wobbler syndrome; Dog cadavers (n=3). Methods : Five measurements of the 5th cervical vertebra were performed: vertebral body length (VBL), vertebral canal height (VCH), vertebral body height (VBH), vertebral canal width (VCW), and vertebral body width (VBW). Measurements were performed independently twice by 2 observers. Bland-Altman plots were created to evaluate agreement. Cadaveric vertebrae with soft tissue removed had the same variables and actual dimensions measured. Results : The largest discrepancy between CT and MRI measurement was for VBL (mean difference +/- SD=1.262 mm +/- 1.245; P <.001), with the difference for all the other variables being acceptable. The 1st measurement was significantly higher than the 2nd only for VBL using CT (mean difference=0.476 mm +/- 1.120; P=.009), with all other variables having acceptable differences. Mean difference for all measurements between 2 observers was small, except for VBL using CT (mean difference=0.762 mm +/- 1.042; P <.001). Only the difference for VBL between CT and cadaver specimens was statistically significant. Conclusions : Our results suggest high repeatability and good agreement for most vertebral measurements of interest. VBL measurement using CT was considered problematic. Clinical Relevance : Provided limitations are understood, linear measurements of vertebral dimensions from CT and MRI images can be used clinically.".
