Definition

A chest x-ray is an image of the heart and lungs. A small dose of radiation is used to create the image. It is one of the most common medical tests done.

  • Difficulty breathing

  • Chest pain
  • Chest injury
  • Fever

Possible Complications

Chest x-rays are done using a very small dose of radiation. If you are pregnant or think you may be pregnant, tell your doctor or the x-ray technician. X-rays are generally avoided during pregnancy if possible.

What to Expect

Prior to Test

You will be asked to remove all jewelry from the waist up. You will also put on a hospital gown. A lead apron may be placed over your abdomen and pelvis. This is done to minimize the risk of radiation.

Description of Test

Pictures are usually 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. In most cases, you will 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.

After Test

You will be able to leave after the test is done.
