Overview
Brief Summary
This project aims to study the prognostic ability of various MRI imaging markers in the evaluation of TBI patients. Cognitive, social, and occupational recovery will be measured at each time point, and compared to MRI findings. Healthy volunteers will serve as a comparison to the TBI patients.
It is hypothesized that novel MRI markers of metabolism, hemodynamics, functional connectivity, and tissue microstructure will be related to the clinical status of the patient, as well as their social and occupational outcomes.
Detailed Description
The goal of this study is to identify advanced magnetic resonance imaging markers that can serve as a prognostic marker in the evaluation and management of traumatic brain injury patients. Magnetic resonance imaging and cognitive testing (when possible) will be performed in the acute (within 10 days following injury), and recovery stages (about 1 month, about 6 months,and about 18 months). The relationship between the advanced magnetic resonance imaging markers and the clinical condition of the patient will be evaluated at each time point to determine which combination of imaging markers best describe the current clinical status of the patient and which markers best predict a patient's outcome status.

Outcomes
Primary Outcomes
Identification of advanced MR imaging markers
Time Frame: 18 months post-injury
Systematically study the imaging markers obtained from novel MRI techniques (diffusion tensor imaging (DTI), susceptibility-weighted imaging (SWI), MR spectroscopy, resting state MRI, and arterial spin labeling) and assess the markers for sensitivity.
Secondary Outcomes
- extent of disability(18 months post-injury)
- level of orientation(18 months post-injury)
- level of cognitive function(18 months post-injury)
- level of functional independence(18 months post-injury)
