Concussion pathophysiology in humans remains incompletely understood. Diffusion tensor imaging (DTI) has identified microstructural abnormalities in otherwise normal appearing brain tissue, using measures of fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD). The results of prior DTI studies suggest that acute alterations in microstructure persist beyond medical clearance...
Sport concussion is associated with disturbances in brain function in the absence of gross anatomical lesions, and may have long‐term health consequences. Diffusion‐weighted magnetic resonance imaging (MRI) methods provide a powerful tool for investigating alterations in white matter microstructure reflecting the long‐term effects of concussion. In a previous study, diffusion tensor imaging (DTI)...
