Trial Outcomes & Findings for Imaging the Neuroimmune System in PTSD (NCT NCT04236986)
NCT ID: NCT04236986
Last Updated: 2024-12-09
Results Overview
Time-activity curves will be extracted from brain regions of interest and analyzed using multilinear analysis-1 (t\*=30) incorporating the metabolite-corrected arterial input function to yield \[11C\]PBR28 total volumes of distribution (VT) across brain regions.

Healthy Controls AKA Trauma Exposed Individuals Without PTSD For HIC 2000020347
We will recruit men and women aged 18-55 who have been exposed to trauma without PTSD into the study. Men and women, aged 18-55 years, any race, with a history of trauma exposure.
Trauma-exposed controls will have a CAPS-5 score of 0-22 (no/minimal to mild/subthreshold symptoms) Able to read and write English and to provide voluntary, written informed consent
