X-ray

A chest X-ray (also called chest film) uses a very small amount of radiation to produce an image of the heart, lungs, and chest bones on film. It is done to look at the structures of the chest (bones, heart, lungs), evaluate placement of devices (pacemakers, defibrillators) or tubes placed during hospitalization for treatment and monitoring (catheters, chest tubes) and diagnose lung and cardiac diseases.
