Unusual pattern on PET/CT may indicate COVID omicron variant

SNMMI images of unusual imaging pattern observed on FDG PET/CT or FDG PET/MR that may be due to Omicron COVID-19 infection. Unlike the FDG PET/CT pattern seen with infections from previous strains of COVID-19, with principal involvement of the lungs, this new array of findings is primarily centered in the upper aerodigestive tract and cervical lymph nodes. What does omnicron COVID look like in medical imaging?

SNMMI images of unusual imaging pattern observed on FDG PET/CT or FDG PET/MR that may be due to Omicron COVID-19 infection. Unlike the FDG PET/CT pattern seen with infections from previous strains of COVID-19, with principal involvement of the lungs, this new array of findings is primarily centered in the upper aerodigestive tract and cervical lymph nodes. Specifically, there is prominent, symmetric FDG uptake throughout the nasopharynx, oropharynx and tonsils with or without associated FDG-avid cervical lymphadenopathy, particularly in the suprahyoid neck.
