What is a chest X-ray?
A chest X-ray is a picture of the heart, lungs and bones of the chest.
Why is it done?
A chest X-ray can help your doctor determine if your heart is an unusual shape or if it is larger than it should be. It can also help confirm the presence of a valve disorder and provide important detailed information about your condition and its seriousness. Chest X-rays are useful for diagnosing an enlargement of the heart ( cardiomyopathy ) or heart failure .
What can you expect?
- No special preparation is necessary.
- Having chest X-rays is completely painless and only takes a few minutes.
- Wearing a hospital gown, you will be asked to lie on an X-ray table and a technologist will help to position you properly.
- You will have to hold your breath and lie very still for two to three seconds.
- The X-ray machine is turned on briefly, letting a small beam of X-rays pass through your chest to create an image on special X-ray film.
- Sometimes two pictures are taken – a front and side view.
The X-ray film takes about 10 minutes to develop.
