Example of chest CT patterns of CO-RADS. Axial CT images are categorized as (a) CO-RADS 1, with no features of pneumonia, (b) CO-RADS 2, with features typical for infection other than COVID-19, e.g., bronchial pneumonia, lobar pneumonia, tuberculosis, or fungal infection, (c) CO-RADS 3, with features compatible with COVID-19 but also other diseases, e.g., alveolar pulmonary edema, (d) CO-RADS 4, with features suspicious for COVID-19 but with overlap with other diseases, drug-induced pneumonia or collagen disease-related lung diseases, and (e) CO-RADS 5, with typical pattern of COVID-19 pneumonia [49]
