Figure Lengend Snippet: Correlation matrix of scalar brain tissue volume metrics (plotted on X and Y axis) in experimental TBI rats as a descriptive interpretation. Pairwise Pearson correlation coefficients are shown between nine scalar metrics derived from harmonized diffusion MRI data. The variables include low and high z -score volumes for fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD), along with total atrophy volume (Jacobian z < −3.1). Each entry in the matrix reflects the strength and direction of the linear relationship between two variables across the full dataset.
