Detecting white matter changes of traumatic brain injury (TBI) and understanding their effects on neuropsychological consequence is important in treating and predicting the outcomes of brain trauma. We evaluated the combined tractography and spatial normalization methods, and examined the association between the DTI measures and neuropsychological test results in military TBI patients.
