DTI shows white matter changes in football players

"The more hits a football player's head takes during a season, the more changes show up on MRI of the player's brain, even in the absence of concussion, a new study shows. Researchers used data from helmet sensors to estimate the risks associated with all impacts to the head during a season, then compared these risks to the white matter changes in the players' brain visible by diffusion tensor imaging.  "

Study by: Alexander Powers, MD, an assistant professor of neurosurgery at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina. Dr. Powers presented their findings here at the American Association of Neurological Surgeons (AANS) 82nd Annual Meeting.
