Abdominal X-ray; X-ray - abdomen; Flat plate; KUBDefinition Return to top
Abdominal films are X-ray images 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 Return to top
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 Return to top
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.How the test will feel Return to top
There is no discomfort. The films are taken with you lying on your back, side, and standing.Why the test is performed Return to top
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.Normal Values Return to top
The X-ray will show normal structures for a person your age.What abnormal results mean Return to top
Abnormal findings include:What the risks are 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 low compared with the benefits.
Pregnant women and children are more sensitive to the risks of the X-ray. Women should make the health care provider aware of suspected pregnancy.
Special considerations Return to top
The test is not usually recommended for pregnant women. The ovaries and uterus cannot be shielded during the abdominal X-ray because of their location. Men should have a lead shield placed over the testes to protect against the radiation.
