Chest CT images of a 44-year-old woman. The RT-PCR test was positive. a Axial thin-section chest CT images show minimal ground-glass opacities (GGO) in the subpleural distribution. b, c Images show progressive GGO, mixed GGO and consolidation in the bilateral lung. d Images show thinned GGO, indicating absorption in the bilateral lung. e Images show complete absorption and a normal lung

Chest CT images of a 39-year-old woman. The RT-PCR test was positive. a Axial and coronal images show normal onset. b Images show minimal ground-glass opacities (GGO) in the bilateral lower lung lobes. c Images show progressive mixed GGO and consolidation in the bilateral lung lobes. d Images show reduced GGO and linear opacities in the bilateral lower lung lobes. e Images show thinned GGO, indicating absorption in the bilateral lower lung lobes

Chest CT images of a 38-year-old man. The RT-PCR test was negative. a Axial, coronal, and sagittal images show a solitary, rounded, peripheral ground-glass opacity (GGO) with halo sign and air bronchial sign in the middle lobe of the right lung. b Images show progressive mixed GGO and consolidation in the middle lobe of the right lung. c Images show increased GGO and linear opacities in the middle lobe of the right lung. d Images show reduced GGO and linear opacities, indicating absorption in the middle lobe of the right lung

A chest CT (Fig. 3a) taken before admission on January 25, 2020, showed abnormalities in the middle lobe of the right lung. A virus, influenza B virus, respiratory syncytial virus, parainfluenza virus, adenovirus, chlamydia pneumonia, and mycoplasma pneumoniae) were excluded, and he was clinically diagnosed with suspected COVID-19. A serial follow-up chest CT showed that the lesion was enlarged and partially absorbed after treatment (Fig. 3b-d).
