Chest x-ray

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

  • Alternative Names
    • Chest radiography; Serial chest x-ray; X-ray - chest

  • How the Test is Performed
    • You stand in front of the x-ray machine. You will be told to hold your breath when the x-ray is taken.

      Two images are usually taken. You will first need to stand facing the machine, and then sideways.

  • How to Prepare for the Test
    • Tell the health care provider if you are pregnant. Chest x-rays are generally not done during the first 6 months of pregnancy.

  • How the Test will Feel
    • There is no discomfort. The film plate may feel cold.

  • Why the Test is Performed
    • Your doctor may order a chest x-ray if you have any of the following symptoms:

      • A persistent cough
      • Chest pain from a chest injury (with a possible rib fracture or lung complication) or from heart problems
      • Difficulty breathing
      • Fever

      It may also be done if you have signs of tuberculosis, lung cancer, or other chest or lung diseases.

      A serial chest x-ray is one that is repeated. It may be done to monitor changes found on a past chest x-ray.

  • What Abnormal Results Mean
  • Risks
    • 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 benefits outweigh the risks. Pregnant women and children are more sensitive to the risks of x-rays.
