Abstract:
Bronchography is not routinely done. We analyzed the state of bronchography with questionnaires returned from 57 hospitals. Bronchography is now done at 30 hospitals. The number done in 1992 ranged from 1 to 27 (median 3). Peripheral lung cancer and bronchiectasis were the two most frequent diseases for which bronchography was done. In other hospitals, bronchography was once done, but had been stopped. Two reasons for discontinuation of bronchography are: recent progress in radiographic diagnostic techniques such as high resolution CT, and discomfort of the patient. Now that propyliodone is no longer available, some hospitals may use iopydol-iopydone or iopamidol instead. It is necessary to elucidate the true need for bronchography and for an appropriate contrast medium to take the place of propyliodone.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
