Detecting white matter changes of traumatic brain injury (TBI) and understanding their effects on neuropsychological consequence is important in treating brain trauma. We evaluated the structural connectivity in traumatic axonal injury using diffusion tensor tractography, and examined the association between the measures and neuropsychological function in military TBI patients.
