Alternative names:

Abdominal X-ray; X-ray - abdomen; Flat plate; KUB

Definition:

An X-ray image(s) of the abdomen. X-rays are a form of electromagnetic radiation (like light). They are of higher energy, however, and can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray.

How the Test is Performed

The test is performed in a hospital radiology department or in the health care provider's office by an X-ray technologist. You lie on your back on the X-ray table. The X-ray machine is positioned over your abdominal area. You hold your breath as the picture is taken so that the picture will not be blurry. You may be asked to change position to the side or to stand up for additional pictures.

How to Prepare for the Test

Inform the health care provider if you are pregnant, have an IUD inserted, or have had a barium contrast media X-ray in the last 4 days.

If you have taken any medications such as Pepto Bismol (which contains bismuth) within 4 days mention it to the health care provider, because they may interfere with the test.

You wear a hospital gown during the X-ray procedure. You must remove all jewelry. You must sign an informed consent form.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experiences, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

How the Test will Feel

There is no discomfort. The films are taken with you lying on your back, side, and standing.

Why the Test is Performed

The abdominal X-ray can help identify suspected problems in the urinary system such as a kidney stone, or a blockage or perforation (hole) in the intestine. The X-ray can locate an object that has been swallowed. The X-ray may also help in diagnosing a pain in the abdomen or unexplained nausea.
