Definition
Abdominal films are x-ray images of the abdomen.
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.
How the test will feel
There is no discomfort. The films are taken with you lying on your back, side, and while 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 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
The x-ray will show normal structures for a person your age.
What abnormal results mean
Abnormal findings include:
- Abdominal masses
- Build up of fluid in the abdomen
- Kidney stones
- Certain types of gallstones
- Intestinal blockage
- Foreign object in the intestines (an intestinal obstruction)
- Injury to the abdominal tissue
- Hole in the stomach or intestines
What the risks are
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 tell the health care provider if they are, or may be, pregnant.
Special considerations
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. |
