Pediatric mild traumatic brain injury data is necessary to understanding and predicting recovery of cognitive and psychiatric sequelae as pediatric subjects may take longer to recover than adults. Our study presents MR spectroscopy data acquired in five different brain regions of concussed and non-concussed high school athletes. Data were analyzed utilizing linear discriminant in combination with principal component analysis. Initial results demonstrate reasonable separation of mTBI subjects compared to normal controls. In addition, data from multiple time-points after injury demonstrate a return toward normal pattern and can be used to predict recovery and return-to-play times.
