Figure 3

Test-retest reliability of 1.75 mm isotropic voxel. Panels a–d show the Bland-Altman plots for FA, AD, RD, and MD from one of the participants including the 95% confidence interval for the agreement between scan-rescan. Each symbol represents a white matter region of interest from the DTI Studio parcellation. Panels e–h show the difference in coefficient of variations (CoVs) for FA, AD, MD, and RD between controls and TBI as well as the overall mean CoVs for each diffusion tensor metric. Panels i–l show the linear relationships including the 95% confidence interval band between the FA, AD, MD, and RD and atlas-based white matter tracts z-axis centers for one of the participants. Panels m–p show the slopes of the relationships between z-axis centers and test-retest differences. Panels q–t show the R2s including standard deviation or the linear relationships between the FA, AD, MD, and RD and atlas-based white matter tracts z-axis centers for controls and TBI separately. Abbreviations: FA, fractional anisotropy; AD, axial diffusivity; MD, mean diffusivity; RD, radial diffusivity; TBI; traumatic brain injury.
