Diffusion tensor imaging of incentive effects in prospective memory after pediatric traumatic brain injury.

Few studies exist investigating the brain-behavior relations of event-based prospective memory (EB-PM) impairments following traumatic brain injury (TBI). To address this, children with moderate-to-severe TBI performed an EB-PM test with two motivational enhancement conditions and underwent concurrent diffusion tensor imaging (DTI) at 3 months post-injury. Children with orthopedic injuries (OI; n=37) or moderate-to-severe TBI (n=40) were contrasted.

Diffusion tensor imaging analysis of frontal lobes in pediatric traumatic brain injury.

This study examined the use of diffusion tensor imaging in detecting white matter changes in the frontal lobes following pediatric traumatic brain injury. A total of 46 children (ages 8-16 years) with moderate to severe traumatic brain injury and 47 children with orthopedic injury underwent 1.5 Tesla magnetic resonance imaging (MRI) at 3 months postinjury.
