CT Abnormalities Evocative of Lung Infection Are Associated With Lower 18F-FDG Uptake in Confirmed COVID-19 Patients

CT signs that are evocative of lung COVID-19 infections have been extensively described, whereas 18F-FDG-PET signs have not. Our current study aimed to identify specific COVID-19 18F-FDG-PET signs in patients that were (i) suspected to have a lung infection based on 18F-FDG-PET/CT recorded during the COVID-19 outbreak and (ii) whose COVID-19 diagnosis was definitely established or excluded by appropriate viral testing.

Inclusion Criteria: * Patient coming to nuclear medicine for 18F-flurodesoxyglucose (FDG) positron emission tomography computed tomography (PET-CT) with suspicion of lung involvement * patient affiliated to a social security scheme or equivalent * adult patient having been informed of the study Exclusion Criteria: * patient with a negative covid 19 test
