Projects

Chronic Effects of Neurotrauma Consortium Neuroimaging Core

Funding

Chronic Effects of Neurotrauma Consortium Neuroimaging Core
- #PT12051
Grant funding from Department of Defense and VA
The goals of this project are to investigate late effects of mild TBI in Veterans and Service Members.
Chronic Effects of Neurotrauma (CENC) Longitudinal Cohort Study
Grant funding from Department of Defense and VA
The goal is to establish a large longitudinal case-control cohort Veterans to comprehensively evaluate for the late effects of combat related mTBI, describe the late outcomes and change over time of Veterans with single and repeated mTBI, and establish whether, and to what extent, mTBI(s) is associated with poorer outcome among combat-exposed Veterans.
TBI Biological Diagnosis via High-Definition Tractography Asymmetry Screening.
- #1W81XWH-12-2-0140
Grant funding from Department of Defense
The major goals of the project are to develop High-Definition Tractography Asymmetry Screening (a form of diffusion imaging) methodology and analysis.
Conversion of Clinical Data from the National Acute Brain Injury Trials: Hypothermia I & II into FITBIR
- #14094001
Grant funding from Department of Defense
The goal of this project is to prepare a related group of legacy data sets for addition to the Federal Interagency Traumatic Brain Injury Research Informatics System (FITBIR). Data sets from the National Acute Brain Injury Study: Hypothermia (NABISH) projects will be reviewed, analyzed, and mapped to existing FITBIR data structures; selected variables that do not map to existing International Common Data Elements (CDE), as incorporated into FITBIR, will be identified, described, and formatted for inclusion as Unique Data Elements (UDE) per FITBIR procedures.
Imaging Common Data Elements as Predictors of Long-Term Outcome in Pediatric TBI
Grant funding from National Institutes of Health (NIH/NICHD)
The major goal of this project involves collection and analysis of acute clinical imaging from an existing multi-center study of pediatric TBI (for study entitled “Effect of Treatment on Outcome after TBI in Children and Adolescents” funded by the CDC as indicated below). The imaging data from all project sites in the parent study will undergo centralized analysis by a pediatric neuroradiologist to derive Federal Interagency Traumatic Brain Injury Research (FITBIR)-compatible, comprehensive neuroimaging CDEs for TBI.
Research Enhancement Award Program (REAP)
Grant funding from VA
Using Individual DTI Profiles of Mild TBI to Guide Targeted, Non-Invasive Brain Stimulation Intervention for Veterans with Persistent Post-Concussion Symptoms.
Grant funding from Department of Defense and VA
Our main objective is to use, for the first time, a novel reference brain atlas to create subject-specific profiles of brain injury to guide targeted transcranial direct conduction stimulation (tDCS) to treat individual brain regions of injury for each Veteran suffering from mild traumatic brain injury (mTBI) with persistent post-concussive symptoms (PPCS).
Diffusion Tensor Imaging Standardization using Novel MR Diffusion Phantoms
Grant funding from VA
In this proposal, we will use diffusion imaging phantoms to evaluate differences between scanners with the goal of providing acquisition techniques that will data to be compared across different patient groups and combined into large data collections. Our objective is to provide a means for the many different scanners across the VA hospital system.
Imaging and Biomarkers in Adolescents Cleared for Return to Play After Concussion
Grant funding from National Institutes of Health (NIH/NINDS)
The goal of this project is to investigate advanced neuroimaging findings which may be evident even after high school athlete subjects are cleared to return to play following a concussion.
A Psychiatric and Imaging Study of Pediatric Mild Traumatic Brain Injury
- #HD068432
Grant funding from National Institutes of Health (NIH/NICHD)
The overall goal of the proposed project is to study injury and psychosocial risk factors for the development of new psychiatric disorders in children with mild TBI in relation to advanced neuroimaging.
A Longitudinal Study of Chronic TBI in OEF/OIF/OND Veterans and Service Members.
- #VA 1 I01 RX001062
Grant funding from VA
The overall goal of this project is to characterize the long-term effects of TBI on cognition, neuroimaging, and functional outcome in Veterans and service members who have been deployed to Iraq or Afghanistan.
An fMRI Study of Deployment-related TBI in Veterans and Service and Members
- #VA 1 I01 RX001320H
Grant funding from VA
The major goals of this project are to investigate the effects of mild traumatic brain injury through a converging fMRI study of attention networks wherein we would integrate DTI measurement of injury to tracts with analysis of fMRI data. In addition, we propose the evaluation of TBI effects on resting state connectivity of the default mode network (DMN), a network which has been implicated in attention and exhibits changes with both mTBI and PTSD.
Automated Assessment of White Matter Integrity in Traumatic Brain Injury Using Machine Learning
- #VA 1 I21RX001565
Grant funding from VA
The major goal of this project is to investigate the use of a Support Vector Machine (SVM) classifier to systematically distinguish differences in white matter integrity between Veterans with and without mild traumatic brain injury.
HypOthermia for Patients requiring Evacuation of Subdural Hematoma: a Multicenter, Randomized Clinical Trial (HOPES Trial)
Grant funding from University of Texas Health Sciences Center at Houston, with support from Vivian L. Smith Foundation and Zoll Medical
The goal of this project is to investigate the use of moderate hypothermia in acute severe TBI.
