abstract	PURPOSE: To evaluate the chest CT findings in an environmentally homogeneous cohort from the cruise ship “Diamond Princess” with Coronavirus Disease 2019 (COVID-19). MATERIALS AND METHODS: This retrospective study comprised 104 cases (mean age, 62 years ± 16, range 25-93) with COVID-19 confirmed with RT-PCR. CT images were reviewed and the CT severity score was calculated for each lobes and the entire lung. CT findings were compared between asymptomatic and symptomatic cases. RESULTS: Of 104 cases, 76 (73%) were asymptomatic, 41 (54%) of which had lung opacities on CT. Other 28 (27%) cases were symptomatic, 22 (79%) of which had abnormal CT findings. Symptomatic cases showed lung opacities and airway abnormalities on CT more frequently than asymptomatic cases [lung opacity; 22 (79%) vs 41 (54%), airway abnormalities; 14 (50%) vs 15 (20%)]. Asymptomatic cases showed more GGO over consolidation (83%), while symptomatic cases more frequently showed consolidation over GGO (41%). The CT severity score was higher in symptomatic cases than asymptomatic cases, particularly in the lower lobes [symptomatic vs asymptomatic cases; right lower lobe: 2 ± 1 (0-4) vs 1 ± 1 (0-4); left lower lobe: 2 ± 1 (0-4) vs 1 ± 1 (0-3); total score: 7 ± 5 (1-17) vs 4 ± 2 (1-11)]. CONCLUSION: This study documented a high incidence of subclinical CT changes in cases with COVID-19. Compared to symptomatic cases, asymptomatic cases showed more GGO over consolidation and milder extension of disease on CT. An earlier incorrect version appeared online.
