    Snippet: The CT images were acquired on admission and at intervals of 3-5 days and were reviewed independently by two experienced radiologists. Typical CT findings for COVID-19 were defined as peripherally distributed multifocal ground-glass opacities (GGOs) with patchy consolidations and posterior part or lower lobe involvement predilection. 20 Each of the five lung lobes was reviewed for GGO and consolidation.

    Document: The CT images were acquired on admission and at intervals of 3-5 days and were reviewed independently by two experienced radiologists. Typical CT findings for COVID-19 were defined as peripherally distributed multifocal ground-glass opacities (GGOs) with patchy consolidations and posterior part or lower lobe involvement predilection. 20 Each of the five lung lobes was reviewed for GGO and consolidation. The lesions extent within each lung lobe was semi-quantitatively evaluated by scoring from 0 to 5 based on the degree of involvement: score 0, none involvement; score 1, ≤ 5% involvement; score 2, 6%~25% involvement; score 3, 26%~50% involvement; score 4, 51%~75% involvement; score 5, > 75% involvement. The total score was calculated by summing up scores of all five lobes to provide a lung CT score ranging from 0 to 25. 21 The mean value of lung CT scores evaluated by the two radiologists was used for analysis.
