Title: Some principles of interpretation of bronchograms
Abstract: The conduction of contrast medium to the periphery of the bronchial tree depends upon the negative intrathoracic pressure which occurs during inspiration. Provided that the technique of bronchography is satisfactory, even the smallest branches of a normal bronchial tree should all be delineated. A normal bronchus presents a “tubular” appearance. If a bronchus casts a “solid” shadow this may either be the result of over-filling of a normal bronchus (in which case peripheral “filling” is complete) or it may be due to insufficient peripheral suction (the latter being distinguishable by an absence of peripheral “filling”). Loss of normal parallelism of bronchial walls or the presence of localised protrusions from them (such as those caused by mucous gland ducts) are not found in normal bronchi.
