Concussion is a severe health problem and occurs extremely common in contact sports. Clinical MRI is typically used to detect brain abnormalities following injury. However, focal brain pathologies are rarely found. We applied a local spatial frequency-based texture analysis method to evaluate whether invisible MRI changes exist and how they evolve following concussion. Results show that T2 texture spectra decreased uniformly at 2 weeks, continuing at 2 months before recovering thereafter towards baseline in concussed subjects. There were no changes in the non-concussed groups. Advanced texture analysis of clinical MRI may help monitor subtle brain structural changes following concussion.
