Bronchoscopy is a test that allows a doctor to view the airways (bronchi) with the use of a thin, lighted tube containing a camera. The tube used in bronchoscopy may be flexible or rigid. The flexible scope is most often used. The rigid scope is a straight tube and is only used to view the larger airways. Bronchoscopy, also called fiberoptic bronchoscopy, is used to diagnose and sometimes treat lung conditions.
