Abstract :
Diffusion tensor imaging (DTI) analysis is performed on a subject that exhibits visual dysfunction as a result of mild traumatic brain injury (TBI). A comparison is made of the subject´s DTI data before and after undergoing vision training in order to quantify any differences in the subject´s fractional anisotropy (FA) and white matter fiber tracts. A marked increase is seen in the FA values of the designated regions of interest (ROI) as well as in the number of fibers that are present in the ROIs.
