Chest Imaging

Bronchography

diagnostic procedure commonly used in the past to diagnose bronchiectasis (Fig.1), the site and extent of bronchial obstruction, congenital bronchial abnormalities and bronchopleural fistulae. It has now been almost completely superseded by HRCT.

Propyliodone, in either an oily or aqueous suspension, has been the most commonly used contrast agent. When bronchoscopy is now performed it is usually a selective examination and undertaken at the time of fibreoptic bronchoscopy under which circumstances a low osmolar contrast agent is used. Also, see bronchography.
