The associated funding source was ended, and the proposed duration of the study ended.

The primary goal of this project is to study the feasibility of a prototype brain-dedicated PET insert for an MR scanner for simultaneous acquisition of PET/MR images of metabolism and perfusion in Covid-19 negative and positive/once positive subjects. This study serves as a pilot study for establishing an imaging protocol for combined PET and MR derived functional information as well as MRI acquired anatomical information.

This study is a non-randomized non-treatment study. The intention of this work is an assessment of the PET insert technology, and not, for example, to perform a treatment assessment or drug assessment. This work will actively recruit 10 individuals (5 Covid-19 negative and 5 Covid-19 previously positive in the last 180 days) to perform imaging of the brain with an FDA-approved radiotracer.

Inclusion Criteria:

1. Whole body radiation dose in the last year of less than 5000 mrem determined via subject verbal history reporting
2. Must be at least 21 years of age
3. Deemed healthy to endure duration of imaging study as confirmed via study PI
4. Proof of COVID-19 viral or antibody testing within the timeframe of >20 days but <=180 days prior to scan.

Exclusion Criteria:

1. History of non-MRI compatible surgeries, implants, or activities
2. Pregnant or nursing
3. History of allergic reactions to PET radiotracers (via patient verbal report and /or medical record review.
