Discrepancies in the clinical and radiological profiles of COVID-19: A case-based discussion and review of literature

Table 1 Coronavirus disease-19 Reporting and Data System category of computed tomography reporting and the level of suspicion for coronavirus disease-19[41]

Category	Level of suspicion	Summary of CT observation and interpretation
CO-RADS 0	Cannot interpret	Due to technically insufficient CT scan
CO-RADS 1	Very low	Normal CT chest or non-infectious CT chest
CO-RADS 2	Low	Typical for other infections like lobar consolidation
CO-RADS 3	Equivocal	Features compatible with COVID-19 & other infections
CO-RADS 4	High	Suspicious CT features of COVID-19
CO-RADS 5	Very high	Typical CT features of COVID-19
CO-RADS 6	Proven (RT-PCR)	RT-PCT positive for SARS-CoV-2 RNA
