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 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 کاملDepression after traumatic brain injury.
Antidepressant medications work by rebalancing the natural chemicals (neurotransmitters) in the brain to improve mood, energy, concentration, sleep, appetite, and anxiety. It is important to know that antidepressants are not addictive and usually do not need to be taken forever. Since each person’s situation is unique, always plan your antidepressant schedule with a doctor. There are many diffe...
متن کاملDiagnostic Challenge of Diffusion Tensor Imaging in a Patient With Hemiplegia After Traumatic Brain Injury
A 51-year-old man showed hemiplegia on his right side after a traumatic brain injury (TBI). On initial brain computed tomography (CT) scan, an acute subdural hemorrhage in the right cerebral convexity and severe degrees of midline shifting and subfalcine herniation to the left side were evident. On follow-up brain magnetic resonance imaging (MRI), there were multiple microhemorrhages in the lef...
