Pulmonary opacification

Last revised by Dr Henry Knipe on 16 May 2020

Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is. The patterns can broadly be divided into airspace opacification, lines and dots.
