The plain AP films of this patient exemplify pulmonary edema. One can easily appreciate the fluffy white opacities throughout the lung field. Other signs such as vascular redistribution, peri-bronchial cuffing, and pleural effusion are difficult to appreciate on this...

This young patient has emphysema as a result of alpha-1-antitrypsin deficiency. Hyperinflation is noted as a generalized increase in radiolucency due to increased aeration and spread of vasculature, an increased AP chest diameter and retrosternal airspace on the...

Emphysema (PA Film) (left image) Hyperinflation, darkened lung fields, and decreased vascular markings. Emphysema (Lateral Film) (right image) Large retrosternal airspace, increased AP diametre (barrel chest), flattened hemi-diaphragms.

Bullae are often associated with emphysema. By definition, a bulla is a gas-containing, avascular area of lung at least 1 cm in diameter and with a wall thickness of at least 1 mm. The arrows indicate bullae visible on the chest x-ray (left) and CT scan (right) of a...

The air bronchograms seen in this chest x-ray and CT scan represent lucent branching bronchi visible through surrounding (opaque) airspace disease.

The acinar pattern is representative of airspace disease. Seen are ill-defined, round or elliptical nodules measuring 4–8 mm. They have a characteristic “fluffy” appearance and may take on a patchy distribution, with a later tendency to coalesce into a lobar or...

To assess rotation of the film, compare the distance between a spinous process to each of the clavicles. If the supinous process is closer to one clavicle, that side is rotated posteriorly.
