We investigated chronic white matter changes in high school and collegiate football players with history of sport-related concussion using diffusion kurtosis tensor imaging. Results demonstrated that the symptoms normalized after one week but, mean diffusivity remained significantly low in concussed football players. These findings have implications for determination of recovery following concussion.
