Diffusion tensor imaging of neural plasticity in visual dysfunction

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.
