Concussion is an alteration in mental status after trauma induced biomechanical forces affect the brain that may or may not involve loss of consciousness. Structural scans, such as MRI and CT, have little utility in concussions since there are little to no detectable pathological changes in concussive injury. Next generation imaging modalities such as fMRI and diffusion tensor imaging (DTI) have demonstrated some promise as biomarkers in concussion injury. DTI measures the integrity of white matter tracts indirectly by assessing the degree and direction of water diffusion through the brain. fMRI abnormalities provide predictive insight into time to recovery; those athletes with the greatest extent of fMRI activation took almost twice as long to recover from their injury than did the less affected athletes.
