Diffusion tensor imaging and traumatic brain injury.
Traumatic brain injury (TBI) is a leading cause of mortality and morbidity in Americans, especially those under age 45. TBI accounts for more than 500,000 emergency department visits annually (Nirula et al., 2003). Closed head injury produces cerebral edema, hemorrhage, contusions, and ischemia. Diffuse axonal injury (DAI) is also a common consequence of head trauma, and results from rotational...
متن کاملEmotional prosody and diffusion tensor imaging in children after traumatic brain injury.
PRIMARY OBJECTIVE Brain structures and their white matter connections that may contribute to emotion processing and may be vulnerable to disruption by a traumatic brain injury (TBI) occurring in childhood have not been thoroughly explored. RESEARCH DESIGN AND METHODS The current investigation examines the relationship between diffusion tensor imaging (DTI) metrics, including fractional anisot...
متن کاملDiffusion tensor imaging in the corpus callosum in children after moderate to severe traumatic brain injury.
Diffusion tensor imaging (DTI) is a recent imaging technique that assesses the microstructure of the cerebral white matter (WM) based on anisotropic diffusion (i.e., water molecules move faster in parallel to nerve fibers than perpendicular to them). Fractional anisotropy (FA), which ranges from 0 to 1.0, increases with myelination of WM tracts and is sensitive to diffuse axonal injury (DAI) in...
متن کاملDiffusion tensor imaging in mild traumatic brain injury litigation.
A growing body of literature addresses the application of diffusion tensor imaging (DTI) to traumatic brain injury (TBI). Most TBIs are of mild severity, and their diagnosis and prognosis are often challenging. These challenges may be exacerbated in medicolegal contexts, where plaintiffs seek to present objective evidence that supports a clinical diagnosis of mild (m)TBI. Because DTI permits qu...
متن کاملWhite matter and reading deficits after pediatric traumatic brain injury: A diffusion tensor imaging study
Pediatric traumatic brain injury often results in significant long-term deficits in mastery of reading ability. This study aimed to identify white matter pathways that, when damaged, predicted reading deficits in children. Based on the dual-route model of word reading, we predicted that integrity of the inferior fronto-occipital fasciculus would be related to performance in sight word identific...
