Reasons for Test

X-rays can be taken of any part of the body. They are especially good for looking at teeth and injuries to bones.

X-rays can also be used to:

  • Find an infection, especially pneumonia
  • Look for evidence of arthritis
  • Diagnose heart and large blood vessel problems
  • Look for fluid in the lungs
  • Look for problems in the abdomen

By using oral, rectal, bladder or intravenous contrast materials they can used for other reasons, including:

  • Looking at the stomach and intestines, gall bladder, or liver
  • Small blood vessel disease
  • Urinary tract or reproductive syatem abnormalities
  • Bleeding
  • Locating tumors

Possible Complications

An x-ray uses radiation to make images. The low levels of radiation from a single x-ray will not affect 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.

You may be given a type of contrast material.

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.
