Synopsis

American football players were examined before and after a season of the German Football League. High resolution quantitative MRI at 7T for evaluations of volumetric changes and alterations in T1 relaxation times of various brain regions was performed. Age- and gender-matched subjects with no history of contact and collision sports served as a control group. In addition, structural susceptibility weighted imaging was compared between 3T and 7T. Loss of gray matter volume and an overall increase in T1 relaxation times were observed in players between both scans. SWI was superior in detecting cerebral microbleeds at 7T compared to 3T.
