Propyliodone (INN, trade name Dionosil) is a molecule used as a contrast medium in bronchography. [1] It was developed by a team at Imperial Chemical Industries [2] in the late 1930s.
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.
