Bronchograms were made in eight men, chosen on clinical grounds as representative of three grades of severity in a series of 67 male bronchitis studied prospectively over a period of 10 years, with the object of ascertaining the anatomical condition at the end of this period. In the stationary group the bronchograms showed only a mild mucous reaction, and peripheral filling was generally good. In the slowly progressive group, mucous obstruction was evident and fairly widespread, and organic changes were present, though not widespread or severe. In the progressive group, both mucous obstruction and organic change were widespread. It was noted that when both mucous obstruction and organic changes were observed the upper lobes were seen to be relatively normal with the exception of the progressive cases in which all changes were more severe. The bronchographic abnormalities were found to be closely correlated with the grades of clinical severity.. ...

Bronchiectasis is generally considered irreversible in the adult population, largely based on studies employing bronchography in cases with a significant clinic

A bronchography is a radiographic (x-ray) examination of the interior passageways of the lower respiratory tract. The structures of the lower respiratory tract, which include the larynx (voice box), trachea (windpipe), and bronchi (larger branching airways to the lungs), become visible on x-ray film after contrast dye is instilled through either a catheter or bronchoscope (narrow, flexible, lighted tube) into these areas. Contrast dye is a substance that causes a particular organ, tissue, or structure to be more visible on x-ray or other diagnostic images.. The contrast dye is released as the catheter or bronchoscope is inserted through the nose or mouth and advanced down the throat into the trachea and bronchi. The contrast dye forms a coating on the lining of the interior walls of these structures, thus outlining their anatomy on x-ray. In addition, abnormalities such as tumors, cavities, cysts, and obstructions may be revealed.. As a result of improved computerized tomography (CT scan) and ...
