Quantitative MRI as an imaging marker of concussion: evidence from studying repeated events

Abstract

We present a 23‐year‐old male professional Australian Football player who experienced a total of seven sports‐related concussions between May‐2015‐March‐2019, not associated with loss of consciousness (see supplementary materials for clinical details). Advanced brain imaging was performed after the latter four of these, revealing that his brain underwent a pattern of focal, but transient, increases in T2 relaxometry following concussive events.
