    Reasons for Test

    X-rays can be taken of any part of the body. They are especially good for looking at injuries to bones.
    X-rays can also be used to:
    • Find an infection
    • Locate tumors
    • Look for fluid in the lungs
    • Look for problems in the abdomen
    • Diagnose heart and large blood vessel problems

    Possible Complications

    An x-ray uses radiation to make images. The low levels of radiation from a single x-ray will not effect most people. If you are pregnant or think you may be pregnant talk to your doctor before the x-ray. Radiation may be harmful to developing babies.

    What to Expect

    Prior to Test

    Before your x-ray is taken, you may be asked to remove jewelry and put on a hospital gown.
    Let your doctor know if you are pregnant.

    Description of Test

    A lead shield may be placed on parts of your body that are not being x-rayed. This will help reduce your exposure to radiation.
    The x-ray device will be placed over the part of your body being studied. You will be asked to remain as still as possible while the images are taken. The x-ray device will send x-rays through your body. The x-rays will be captured on the other side of your body by a computer or on film.

    After Test

    You will be able to resume your daily activities after the x-ray is complete.

    How Long Will It Take?

    A few minutes

    Will It Hurt?

    No

    Results

    The x-ray will be sent to a radiologist. A report will be sent to you and/or your doctor.

    Call Your Doctor
