Unlike ground glass attenuation, which is increased attenuation that does not obscure the underlying vessels, consolidation obscures the underlying vessels and usually shows air bronchogram / bronchiolograms.
This can also be subpleural or bronchocentric (red arrows), usually associated with ground glass (yellow arrow), which in turn either forms a halo or is at the center of a reverse halo, as shown yesterday or just randomly distributed together.
The pattern of consolidation is typically that of an organizing pneumonia pattern.
