Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators plan to enroll up to 60 adult subjects in this study. There will be three groups of up to 20 subjects each in this study. Group 1: individuals with OUD and a history of at least one opioid-related OD in the past 5 years that required naloxone treatment reversal: OUD/OD+ Group 2: individuals with OUD without a lifetime history of opioid-related OD OUD/OD- Group 3: Healthy controls without a lifetime OUD: HCs PET/CT imaging will be used to evaluate the uptake of tau in the brain using the investigational radiotracer \[18F\]PI-2620.
