What is the meaning of Bronchogram?

Medical Definition of bronchogram : a radiograph of the bronchial tree after injection of a radiopaque substance.

How is a Bronchogram performed?

Bronchography is performed by instilling contrast material via a catheter or a bronchoscope and performing plain radiographic imaging. It should be performed only at facilities and by operators skilled in its use.

What diagnosis does the presence of air Bronchograms suggest?

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.

What are the indication of bronchography?

Indications for bronchography are much the same in children and adults, but the method can be used for the diagnosis of cystic disease of the lung, tracheo-esophageal fistula, congen- ital anomalies and also for the pulmonary manifestations of fibrocystic disease of the pancreas.

What causes Bronchograms?

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 does bronchial thickening mean?

Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse).

Is Bronchogram and bronchoscopy the same?

Bronchoscopy and bronchogram (B&B) is a combination of two tests. Firstly, a camera contained in a flexible tube (bronchoscope) is inserted into the airway to look closely at the airway wall. This allows us to see if the lining of the airway is inflamed or compressed.

What disease has air bronchograms?

In pulmonary consolidations and infiltrates, air bronchograms are most commonly caused by pneumonia or pulmonary edema (especially with alveolar edema). Other potential causes of consolidations or infiltrates with air bronchograms are: Pulmonary edema.

What contrast is used in bronchography?

Barium sulfate demonstrated acceptable images with virtually no histologic changes. Conclusion: From the histologic and imaging results, barium is the best available contrast material for bronchography.

What is pathogenesis of bronchiectasis?

Abstract. Non-cystic fibrosis bronchiectasis is a heterogeneous condition and its pathogenesis is still not well defined. A combination of a defect in host defense and bacterial infection allows microbial colonization of the airways resulting in chronic inflammation and lung damage.

What is an air bronchogram?

Dr Behrang Amini et al. 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 causes an opacified bronchogram?

It is almost always caused by a pathologic airspace/alveolar process, in which something other than air fills the alveoli. Air bronchograms will not be visible if the bronchi themselves are opacified (e.g. by fluid) and thus indicate patent proximal airways.

What are the contraindications for Bronchography?

Contraindications for bronchography may include pregnancy, a productive cough, acute respiratory infection, and respiratory insufficiency. There may be other risks depending upon your specific medical condition. Be sure to discuss any concerns with your physician prior to the procedure.
