We present findings of longitudinal quantitative susceptibility mapping measurements on a cohort of contact sport athletes that were imaged longitudinally (24 hour, 8 day, 6 month) following diagnosed sport-related concussions (N=22). A cohort (N=29) of contact sport controls was imaged longitudinally using the same protocol and allowed stability assessment stability of the measurement. In regions of high stability, changes in susceptibility after injury were assessed in comparison to an atlas constructed from the control data. Substantial susceptibility variations after injury were found in the deep brain nuclei, which recovered and stabilized in the following two measurement points.
