What does an air bronchogram indicate?
Air bronchogram refers to the phenomenon of air-filled bronchi (dark) being made visible by the opacification of surrounding alveoli (grey/white). It is almost always caused by a pathologic airspace/alveolar process, in which something other than air fills the alveoli.
What is air bronchogram on chest xray?
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.
What disease has air bronchograms?
Traditionally, the air bronchogram sign is used for diagnosis of alveolar disease with rare exceptions. In our study, the air bronchogram sign was defined as an air-containing bronchus or bronchioles within the SPL in lung cancer, bronchiectasis, and pneumonia.
Are air bronchograms normal?
For lung nodules, air bronchograms used to be associated with infectious causes of consolidation and, therefore to be benign. However, in the setting of a lung nodule, an air bronchogram is actually more frequent in malignant than in benign nodules.
How is a Bronchogram performed?
Bronchography is a radiological technique, which involves x-raying the respiratory tree after coating the airways with contrast. Bronchography is rarely performed, as it has been made obsolete with improvements in computed tomography and bronchoscopy.
Do you see air bronchograms in atelectasis?
Air bronchograms can be seen with several processes: pulmonary consolidation. pulmonary edema: especially with alveolar edema. non-obstructive atelectasis.
What is traction bronchiectasis?
Bronchiectasis is irreversible dilation of the bronchi resulting from airway damage due to a variety of causes, including infection, airway obstruction, or fibrosis. 7.
Is there a procedure to remove mucus from lungs?
Common reasons for needing bronchoscopy are a persistent cough, infection or something unusual seen on a chest X-ray or other test. Bronchoscopy can also be used to obtain samples of mucus or tissue, to remove foreign bodies or other blockages from the airways or lungs, or to provide treatment for lung problems.
What is the difference between bronchiectasis and traction bronchiectasis?
Bronchiectasis is irreversible dilation of the bronchi resulting from airway damage due to a variety of causes, including infection, airway obstruction, or fibrosis. By definition, traction bronchiectasis results from fibrotic tissue “pulling” on the bronchi, while freestanding bronchiectasis is unrelated to fibrosis.

What does bronchiectasis look like on CT scan?
A radiologist will associate bronchiectasis with the typical chest computed tomography (CT) scan features, consisting of an abnormally widened and thickened airway with an irregular wall, lack of tapering and/or visibility of the airway in the periphery of the lung [2].
How is a Bronchogram done?
What is an air bronchogram sign on CT?
The SPL on CT showed radiolucent bronchi within lesions, manifesting as air bronchogram sign. The air bronchogram sign was first described by Fleischner [6] and named by Felson, [7] to distinguish pulmonary parenchymal lesions from extrapulmonary processes such as pleural effusion.

How many patients with lung cancer are evaluated for air bronchogram sign?
A total of 105 patients (including 39 cases of lung cancer, 43 cases of tuberculosis, and 23 cases of pneumonia) with SPLs were evaluated for the CT features of air bronchogram sign in this retrospective study.
What does the bronchi look like on a CT scan?
On computed tomography (CT), the bronchi are normally visible through much of the lung. In Figure 7-1B , a right bronchus ( arrow ) appears tubular (in plane) and a left bronchus ( arrow ) appears circular (perpendicular to plane).
