At all follow-up sessions, football athletes (FBA) exhibited significantly (p < 0.001) greater spatial extents of substantial increase/decrease in FA and MD, within ROI_ALT, than did noncollision athletes (NCA). Box-and-whisker plots are presented at each follow-up session for (A) ‖$\text{roi}\_\Delta {\text{FA}}_{\text{ALT},j,i}^{+}$‖; (B) ‖$\text{roi}\_\Delta {\text{MD}}_{\text{ALT},j,i}^{+}$‖; (C) ‖$\text{roi}\_\Delta {\text{FA}}_{\text{ALT},j,i}^{-}$‖; (D) ‖$\text{roi}\_\Delta {\text{MD}}_{\text{ALT},j,i}^{-}$‖.
