COMMENTS

Findings of apparent cardiomegaly and pulmonary vascular congestion must be viewed in the light of possibility of a poor inspiratory effort. This is determined by noting the level of the diaphragm relative to the posterior ribs. With the high diaphragms characteristic of a forced expiration, it is natural that pulmonary vascular markings will be more crowded and may give the appearance of congestion but the lungs will lack Kerley B lines or bronchial cuffing.
