A chest x-ray is an image of the heart and lungs and other structures in the chest. A small dose of radiation is used to create the image. It is one of the most common medical tests done.
Chest x-rays are done to look for abnormalities of your heart, lungs, bones, or blood vessels in your chest. Your doctor may order a chest x-ray if you have certain symptoms, such as:
- Bad or persistent cough
- Difficulty breathing
- Coughing up blood
- Chest pain
- Chest injury
