Definition    Return to top

A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.

How the Test is Performed    Return to top

The test is performed in a hospital radiology department or in the health care provider's office by an x-ray technician. Two views are usually taken: one in which the x-rays pass through the chest from the back (posterior-anterior view), and one in which the x-rays pass through the chest from one side to the other (lateral view). You stand in front of the machine and must hold your breath when the x-ray is taken.

How to Prepare for the Test    Return to top

Inform the health care provider if you are pregnant. Chest x-rays are generally avoided during the first six months of pregnancy. You must wear a hospital gown and remove all jewelry.

How the Test Will Feel    Return to top

There is no discomfort. The film plate may feel cold.

Why the Test is Performed    Return to top

A chest x-ray may be ordered when a person's symptoms include a persistent cough, coughing up blood, chest pain, a chest injury, or difficulty in breathing. The test is also used when tuberculosis, lung cancer, or other chest or lung disease is suspected.

A serial chest x-ray (repeated or sequential) may be used to evaluate changes (for example, an increase in the size of an abnormality) found on a previous chest x-ray.

Risks    Return to top

There is low radiation exposure. X-rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image. Most experts feel that the risk is very low compared with the benefits. Pregnant women and children are more sensitive to the risks of the x-ray.
