2024年7月22日 · An air bronchogram occurs when endobronchial air is visible against a background of increased lung opacity. Expulsion of gas from the parenchyma is partial or complete and can be due to atelectasis and/or replacement by fluid, inflammatory cells, blood, tumor or interstitial thickening.

2021年1月16日 · Air-bronchograms are gas-filled bronchi surrounded by alveoli filled with fluid, pus or other material 1. It is a very useful sign because it is highly sensitive and specific for the presence of lung consolidation rather than collapse.
Air bronchogram - Wikipedia
An air bronchogram is defined as a pattern of air-filled bronchi on a background of airless lung. [1] In pulmonary consolidations and infiltrates, air bronchograms are most commonly caused by pneumonia or pulmonary edema (especially with alveolar edema). [2][3] Other potential causes of consolidations or infiltrates with air bronchograms are: [2]

2024年7月11日 · Air bronchograms are a crucial X-ray finding that can provide valuable insights into the underlying lung pathology. They appear as linear or branching structures within areas of consolidation or fluid accumulation in the lungs.
Air Bronchogram - Chest Radiology
An air bronchogram is a tubular outline of an airway made visible by filling of the surrounding alveoli by fluid or inflammatory exudates. Six causes of air bronchograms are; lung consolidation, pulmonary edema, nonobstructive pulmonary atelectasis, severe interstitial disease, neoplasm, and normal expiration.

2022年1月5日 · An air bronchogram is a pattern of air-filled (low-attenuation) bronchi on a background of opaque (high-attenuation) airless lung. The sign implies (a) patency of proximal airways and (b) evacuation of alveolar air by means of absorption (atelectasis) or replacement (eg, pneumonia) or a combination of these processes.
Fundamental Radiological Findings: Air Bronchograms
2016年1月7日 · Air bronchograms are a sign of airspace disease within the lung, and can be seen in the context of hazy opacities. It is the presence of fluid or soft tissues in the air that normally sounds the bronchus that makes the bronchus become visible.
Air bronchograms: What are they? Pathologies, Mechanism and …
The air bronchograms are a sign of pathology in the air space that exists within the lung when observed as nebulous opacities. The air bronchogram can be defined as fluid or soft tissue in the bronchus area that should usually be full of air and that allows it to be more visible.
Air Bronchogram
The air column in bronchi beyond 4th order becomes recognizable if the surrounding alveoli is filled, providing a contrast or if the bronchi get thickened. The term air bronchogram is used for the former state and signifies alveolar disease.
