Diffusion 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 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...
متن کاملPathophysiological Concepts in Mild Traumatic Brain Injury: Diffusion Tensor Imaging Related to Acute Perfusion CT Imaging
BACKGROUND A subgroup of patients with mild traumatic brain injury (TBI) experiences residual symptoms interfering with their return to work. The pathophysiological substrate of the suboptimal outcome in these patients is a source of debate. OBJECTIVE To provide greater insight into the pathophysiological mechanisms of mild TBI. METHODS Diffusion tensor imaging (DTI) was performed during fo...
متن کاملDiffusion 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 abnormalities in pediatric mild traumatic brain injury.
Pediatric mild traumatic brain injury (pmTBI) is the most prevalent neurological insult in children and is associated with both acute and chronic neurobehavioral sequelae. However, little is known about underlying pathophysiology and how injuries change as a function of recovery. Fractional anisotropy, axial diffusivity, and radial diffusivity were examined in 15 semi-acute pmTBI patients and 1...
