A chest x-ray (also called chest radiography) is the most commonly performed diagnostic examination. A chest radiography makes images of the heart, lungs, airways, blood vessels and the bones of the spine and chest. The procedure is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body.
X-rays are the oldest and most frequently used form of medical imaging and most often used to diagnose or monitor treatment for conditions such as:
- lung cancer (as well as a variety of lung treatments and conditions)
