Reasons for Procedure
Chest x-rays are done to look for abnormalities of the heart, lungs, bones, or blood vessels in the chest. Your doctor may order a chest x-ray in response to certain symptoms or to help diagnose a medical condition.
Common symptoms requiring a chest x-ray include:
- Bad or persistent cough
- Chest pain
- Chest injury
- Coughing up blood
- Shortness of breath
The following conditions can be diagnosed by a chest x-ray:
Risk Factors for Complications During the Procedure
Chest x-rays are done using a small dose of radiation. A lead apron is used to shield the abdomen and pelvis to minimize the risk of even this small dose of radiation. If you are pregnant or suspect you may be pregnant, inform your doctor or the x-ray technician. X-rays are generally avoided during the first two trimesters or throughout pregnancy.
What to Expect
Prior to Procedure
Chest x-rays can be performed in a hospital, an outside lab, or doctor’s office. You will be asked to remove all jewelry from the waist up and put on a hospital gown.
There is no need for anesthesia during a chest x-ray.
Description of the Procedure
Pictures are taken from two different views, a side view and a front view. An x-ray technician will position you according to the type of x-ray machine used. Most commonly you will be asked to stand against the x-ray machine with your hands up or to the side. You will be asked to take a deep breath and hold it while the x-ray is being taken. You will also be asked to stay as still as possible when the film is taken. You may notice that the film cartridge feels cool to your skin.
Once the x-rays are completed you are free to go.
How Long Will It Take?
The process generally takes 10 to 15 minutes.
Will It Hurt?
The procedure is painless.
None, unless you are pregnant
Average Hospital Stay
X-rays do not require hospital stays.
There are no actions to take after x-rays.
A radiologist (a doctor who specializes in x-rays) will evaluate your x-ray and send a report to your doctor. Results are generally available in 1 to 2 days. An abnormal x-ray may require further testing including a chest computed tomography (CT) scan or magnetic resonance imaging (MRI) scan. If an abnormal growth is seen, a biopsy may be ordered.
