Shown first are median and interquartile ranges for 3D bSSFP and 3D IR GRE imaging VIQS scores for each vascular structure identified. P-value column indicates p-value of the test of symmetry for the individual VIQS categories, and results of the Wilcoxon signed-rank test for total VIQS scores. 3D IR GRE Reduced Variability column shows results of Brown-Forsythe testing for equality of group variances. Weighted kappa column shows kappa values of agreement for each VIQS category. Bolded p-values are less than 0.05
