Thin-section chest ct imaging of covid-19 pneumonia: A comparison between patients with mild and severe disease

Abstract

Purpose: To compare radiologic characteristics of coronavirus disease 2019 (COVID-19) pneumonia at thin-section CT on admission between patients with mild and severe disease. Materials and Methods: Seventy patients with COVID-19 pneumonia who were admitted to Zhongnan Hospital of Wuhan University between January 20, 2020 and January 27, 2020 were enrolled. On the basis of the World Health Organization guidelines, 50 patients were categorized with the mild form and 20 with the severe form based on clinical conditions. Imaging features, clinical, and laboratory data were reviewed and compared. Results: Patients with the severe form (median age, 65 years; interquartile range [IQR]: 54.75–75.00 years) were older than those with the mild form of disease (median age, 42.5 years; IQR: 32.75–58.50 years) (P
