Advanced Imaging Tools in the Study of Mild Traumatic Brain Injury

2014-08-27 03:16:51 | BioPortfolio

Summary

We will utilize a set of imaging modalities including computed tomography (CT), positron emission tomography (PET), and a suite of magnetic resonance imaging (MRI) tools, to investigate the changes in the human brain resulting from mild traumatic brain injury (mTBI).

Description

We will recruit mTBI subjects and control subjects. Each subject will undergo the set of imaging modalities, and the results will be analyzed for differences at the structural, physiological, and molecular levels. The long term goal of this research is the development of a method to diagnose mTBI based on physical markers. This is a phased project beginning with a pilot study followed by future studies with larger sample sizes.

Medical and Biotech [MESH] Definitions

Prolonged unconsciousness from which the individual cannot be aroused, associated with traumatic injuries to the BRAIN. This may be defined as unconsciousness persisting for 6 hours or longer. Coma results from injury to both cerebral hemispheres or the RETICULAR FORMATION of the BRAIN STEM. Contributing mechanisms include DIFFUSE AXONAL INJURY and BRAIN EDEMA. (From J Neurotrauma 1997 Oct;14(10):699-713)

A form of acquired brain injury which occurs when a sudden trauma causes damage to the brain.

Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.

Traumatic injuries to the cranium where the integrity of the skull is not compromised and no bone fragments or other objects penetrate the skull and dura mater. This frequently results in mechanical injury being transmitted to intracranial structures which may produce traumatic brain injuries, hemorrhage, or cranial nerve injury. (From Rowland, Merritt's Textbook of Neurology, 9th ed, p417)

Bleeding within the brain as a result of penetrating and nonpenetrating CRANIOCEREBRAL TRAUMA. Traumatically induced hemorrhages may occur in any area of the brain, including the CEREBRUM; BRAIN STEM (see BRAIN STEM HEMORRHAGE, TRAUMATIC); and CEREBELLUM.
