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.

Primary Outcome Measures:
  • 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 Outcome Measures:
  • level of cognitive function [ Time Frame: 18 months post-injury ]
  • extent of disability [ Time Frame: 18 months post-injury ]
  • level of orientation [ Time Frame: 18 months post-injury ]
  • level of functional independence [ Time Frame: 18 months post-injury ]

Estimated Enrollment: 150
Study Start Date: March 2009
Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Severe Traumatic Brain Injury Group
The severe traumatic brain injury group are patients admitted to the study with an admission GCS between 3 and 8.
Moderate Head Injury Group
The moderate head injury group are patients admitted to the study with an admission GCS from 9 to 12.
Mild Head Injury Group
The mild head injury group are patients admitted to the study with an admission GCS from 13 to 15.
Healthy Volunteer Group
Healthy volunteers will be selected to match the age distribution of the TBI groups. They must be absent of any abnormal radiological findings.

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.
