Air Bronchograms on Ultrasound



Opacification of alveolar spaces surrounding air-filled bronchioles; enables visualization of well-defined tissue/air interface; dynamic air bronchograms (AB) are bronchioles still in continuity with central airways, move dynamically with respiration, and are more often seen in infected consolidation; static AB are bronchioles ex-communicated from the main trachea-bronchial tree, often seen secondary to another process including large effusions, substantial atelectasis, but can also be seen in infected consolidation.
