Figure 4.

Longitudinal measures of high anisotropy. This figure presents longitudinal changes in anisotropy measures for patients with mild traumatic brain injury (mild TBI; black bars) and healthy controls (HC; grey bars). Solid bars indicate data from Visit 1 whereas bars with diagonals show Visit 2 data, with all error bars equivalent to the standard deviation. (A) Mean fractional anisotropy (FA) of the genu of the corpus callosum, whereas the number of clusters with high anisotropic diffusion (z ≥ 2.0) and their respective volumes are presented in (B) and (C), respectively. Significant effects are denoted with double asterisks.
