Pilot investigation of a novel white matter imaging technique in Veterans with and without history of mild traumatic brain injury

Objective: The objective of this study is to assess utility of in vivo myelin imaging in combat Veterans with and without history of mild traumatic brain injury (mTBI). We hypothesized that those with history of mTBI would have lower myelin water fraction (MWF), a marker of myelin integrity and content, than those without, and lower MWF would be associated with worse speeded attention/processing speed.Research design: Combat Veterans (N = 70)...
