Study Summary
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.
Primary Outcome
The key specific measurement is that resulting PET/MR images are of high quality, with comparable or better resolution and noise than that seen in other published articles.
Interventions
