Very low suspicion
Very low level of suspicion for pulmonary involvement of COVID-19: either a normal CT or CT findings of an unequivocally non-infectious cause. Concomitant findings such as mild or severe emphysema, perifissural nodules, lung tumours or fibrosis are placed here. Equivalent to the RSNA 'negative for pneumonia' category.
RiscoVery low suspicion of COVID-19 pulmonary involvement.
Low level of suspicion: lung findings typical of an infectious cause considered not compatible with COVID-19 (e.g. bronchitis, infectious bronchiolitis, bronchopneumonia, lobar pneumonia, pulmonary abscess), with features such as tree-in-bud sign, centrilobular nodular pattern, lobar or segmental consolidation, and cavitation. Overlaps with the RSNA 'atypical appearance' category.
RiscoLow suspicion of COVID-19 pulmonary involvement.
Equivocal/indeterminate level of suspicion: features that can also occur in other viral pneumonias or non-infectious causes, e.g. perihilar ground-glass, homogeneous extensive ground-glass (with or without sparing of some secondary lobules), ground-glass with smooth interlobular septal thickening with/without pleural effusion, small non-centrilobular ground-glass opacities not abutting the visceral pleura, and consolidation patterns compatible with organizing pneumonia, in the absence of other typical COVID-19 findings.
RiscoEquivocal/indeterminate suspicion of COVID-19 pulmonary involvement.
High level of suspicion: findings typical for COVID-19 but with some overlap with other (viral) pneumonias. Findings resemble CO-RADS 5 but are not in contact with the visceral pleura, are strictly unilateral, are in a predominantly peribronchovascular distribution, or are superimposed on severe diffuse pre-existing lung abnormalities. Corresponds to the higher-likelihood part of the RSNA 'indeterminate appearance' category.
RiscoHigh suspicion of COVID-19 pulmonary involvement.
Very high level of suspicion: typical CT findings, namely ground-glass opacities (with or without consolidation) located in lung regions close to the visceral pleural surfaces including the fissures, with a multifocal bilateral distribution; subpleural sparing may be present. At least one of the typical confirmatory features must be present (e.g. multifocal ground-glass with rounded/unsharp demarcation, crazy-paving with intralobular lines, increasing consolidation, reverse halo/organizing-pneumonia-like changes, subpleural curvilinear bands, thickened vessels within abnormalities). Largely identical to the RSNA 'typical appearance' category.
RiscoVery high suspicion of COVID-19 pulmonary involvement.
Proven COVID-19, indicated by a positive RT-PCR test for SARS-CoV-2 specific nucleic acid at the time of examination. Introduced analogously to BI-RADS 6.
