Axial CT images are categorized as (a) “Negative for pneumonia” meaning no features of pneumonia, (b) “Atypical appearance”, meaning typical for other infection but not COVID-19, e.g., bronchial pneumonia, lobar pneumonia, tuberculosis, or fungal infection, (c) “Indeterminate appearance”, meaning the presence of feature suspicious for COVID-19 but with overlaps with other diseases, drug-induced pneumonia, collagen disease-related lung diseases, or alveolar pulmonary edema, and (d) “Typical appearance”, meaning the typical pattern of COVID-19 pneumonia [49]
