Description

Highlights: • Chest CT accuracy was 85.4 % during ascending, peak and descending phases of the first Covid-19 wave. • It was not significantly different between chest (4 readers, accuracy 86.4 %) and general (6 readers, accuracy 85.1 %) radiologists, with a probability of equivalence ≥ 95 %. • There were important variations of CT predictive values whereas CT specificity remained stable over time. The purpose of this work was to analyze temporal variations in the diagnostic performance of chest CT for Covid-19 throughout the first wave, depending on disease prevalence variations between the ascending, peak and descending phases of the epidemic in North-Eastern France.
