Comparison of computed tomography (CT) findings with RT-PCR in the diagnosis of COVID-19 in children.

Chest CT findings may provide some clues in predicting RT-PCR positivity in children with a probable diagnosis of COVID-19. Lobe involvement percentage of up to 25% is a finding in favor of patients with positive RT-PCR test, whereas 25%-75% lobe involvement, central and perihilar involvement, and consolidation can be interpreted in favor of patients with negative RT-PCR test.
