Figure 1 Chest computed tomography of critical coronavirus disease 2019 patients with different severity. A: Chest computed tomography (CT) of a 71-year-old man (non-survivor, case 1) showed multifocal and bilateral ground-glass opacities (GGO) in the alveolitis stage (Day 7 of illness); B: Chest CT of a 73-year-old male patient (survivor, case 2) exhibited slight GGO in the alveolitis stage (Day 7 of illness); C: Classified into the fibrosis stage (Day 20 of illness) and Chest CT (case 1) showed bilateral massive shadows of high density and GGO, accompanied by the air bronchogram sign and reticular pattern in the fibrosis stage; and D: Chest CT (case 2) showed that bilateral and multifocal lesions were observed with a combination of mixed GGO, reticular pattern, bronchiectasis and few consolidation (Day 20 of illness).
