This is a single center, single arm exploratory imaging study involving up to two intravenous
microdoses of [18F]F-AraG (the second tracer dose is optional) followed by whole-body PET-CT
imaging in participants with convalescent COVID-19. Up to 20 participants will be enrolled
over an accrual period of approximately 24 months. Each participant will undergo one PET-CT
scan following 50 +/- 10 minutes uptake following a single bolus injection of [18F]F-AraG in
order to determine the tissue distribution of tracer in pariticpants with recent SARS-CoV-2
infection. A second optional [18F]F-AraG dose and PET-CT will be offered approximately 4
months following the initial imaging time point.
