In the earlier days of reading CT scans for suspect Covid-19 cases, an image such as this would have been called suspicious for but not definitive for Covid-19 (CO-RADS 3/4) or “probable” as per the RSNA Consensus Statement.
However, the presence of prominent vessels (red arrows) leading up to or within the areas of ground glass is a sign unique to Covid-19. When these are present, this appearance automatically gets classified as CO-RADS 5 or “typical” Covid-19 disease.
