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 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 کاملDiffusion tensor imaging detects chronic microstructural changes in white and gray matter after traumatic brain injury in rat
Traumatic brain injury (TBI) is a major cause of disability and death in people of all ages worldwide. An initial brain injury caused by external mechanical forces triggers a cascade of tissue changes that lead to a wide spectrum of symptoms and disabilities, such as cognitive deficits, mood or anxiety disorders, motor impairments, chronic pain, and epilepsy. We investigated the detectability o...

متن کاملDiffuse axonal injury in mild traumatic brain injury: a diffusion tensor imaging study.
OBJECT Diffuse axonal injury (DAI) is a major complication of traumatic brain injury (TBI) that leads to functional and psychological deficits. Although DAI is frequently underdiagnosed by conventional imaging modalities, it can be demonstrated using diffusion tensor imaging. The aim of this study was to assess the presence and extent of DAI in patients with mild TBI. METHODS Forty-six patien...
