Pilot Study for PET/MR Imaging of Covid-19

Purpose

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.

Experimental
Covid-19 Negative/Uninfected Population 		5 participants will be recruited, injected with radiopharmaceutical, and imaged on the 3T PETMR with PET insert.
  • Diagnostic Test: Injected radiotracer with PET Insert
    1. Informed consent will be obtained before beginning any study procedures. 2. Participants will receive a small quantity of an FDA approved radiotracer. The PET insert is placed within a 3T MRI scanner, where PET and MRI imaging will be completed.

Detailed Description

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.
