The INjury and TRaumatic STress (INTRuST) Clinical Consortium, led by Dr. Murray Stein, was established to combine the research efforts of the Nation’s leading experts on PTSD and TBI to develop innovative treatments or interventions for those who suffer from PTSD and/or TBI. The INTRuST Consortium was composed of the Coordinating Center, located at the University of California, San Diego (UCSD); 10 competitively selected clinical sites; a Biorepository Core; a Neuroimaging Repository Core; a Biostatistics Core; an Informatics Core; and 19 additional military treatment and Veterans’ facilities—all conducting clinical trials or collecting samples for clinical studies in PTSD and/or TBI.
The INTRuST Neuroimaging Leadership Core (NLC) has served the imaging needs of the INTRuST multi-site clinical trials focused on developing and evaluating interventions to improve the quality of life of those impacted by PTSD and /or TBI. The goals of the INTRuST NLC include but are not limited to (1) providing leadership, coordination, quality control and management of all magnetic resonance (MR) data acquisition, as well as transfer, storage and access for MR structural, diffusion-weighted (DWI), susceptibility-weighted (SWI) and other imaging sets, (2) optimizing and standardizing these imaging protocols across imaging platforms (i.e., GE, Siemens, Philips) and installing and testing specific MR sequences across sites that use different vendors, (3) training of local site personnel in scanning and establishing baseline data sets, (4) performing quality control of images particularly after hardware upgrades, and (5) overseeing data transfer, quality assurance, storage, security, and accessibility. All data has been and continues to be managed by the Central Neuroimaging Data Archive (CNDA) operated by the Neuroinformatics Research Group at Washington University in St. Louis - School of Medicine.
INTRuST NLC specific aims include the creation of uniform imaging protocols that result in equivalent signal- and contrast-to-noise ratios for each Consortium site and the identification, measurement, and minimization of within- and cross-site variability when performing structural (including diffusion-weighted and susceptibility-weighted imaging sequences) and functional MRI studies of patients and healthy controls using a standard set of consortium protocols. Overall, the Core enrolled 438 subjects across the Consortium sites, has completed all structural, DWI, and SWI post-processing tasks, compared structural and diffusion data across sites for normal control subjects, evaluated the reliability of DWI across sites and scanners for mild TBI subjects, and validated a method for harmonizing DWI across sites and scanners for normal control subjects.
