In mid-January of 2021, there were over 95 million diagnosed coronavirus disease 2019 (COVID-19) cases and approximately 2 million deaths worldwide . COVID-19 cases requiring hospitalization or intensive care show changes in computed tomography of the chest with improved sensitivity . Several radiology societies have attempted to standardize the reporting of pulmonary involvement by COVID-19 . The COVID-19 Reporting and Data System (CO-RADS) builds on lessons learned during the peak of the first wave of the pandemic and shows good inter-observer reliability and good performance in predicting moderate to severe disease . We illustrate the application of the CO-RADS classification with imaging from confirmed cases of COVID-19 and discuss differences to other COVID-19 classifications.
