Barium produces a white contrast image of the lining of the colon on x ray and thus, the contour of the lining of the colon may be seen. Detail can be increased if the barium utilized is thinned and air also introduced.

What is in a barium enema that is different than the enema for a colonoscopy?
A barium enema, also known as a lower GI (gastrointestinal) exam, is a test that uses x-ray examination to view the large intestine. There are two types of this test: the single-contrast technique where barium sulfate is injected into the rectum in order to gain a profile view of the large intestine; and the double-contrast (or "air contrast") technique where air is inserted into the rectum.For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below.One reason may be to help in the diagnosis of colon and rectal cancer (or colorectal cancer), and inflammatory disease.Iodine compound is given and z-rays are taken of the intestinal tract
How do you test for the presence of barium ion?
A simple qualitative test is the flame test: barium has a pale/apple green color.
What is the difference between a barium meal and a barium swallow?
Both a barium swallow and a barium meal test involve you swallowing a liquid suspension of barium sulphate before a series of X-rays are taken of your upper digestive tract. In a barium swallow test, X-ray images are taken of your pharynx (throat) and your oesophagus (the passageway that connects your throat to your stomach; sometimes called your gullet). In a barium meal test, X-ray images are taken of your stomach and the beginning of your duodenum (the beginning of your small intestine, the passageway that takes food away from your stomach). A barium meal test is often performed straight after a barium swallow test. Barium is a naturally occurring element that appears white on X-ray. In these tests, the barium is given as a cup of flavoured drink - like a milkshake. When swallowed, barium coats the walls of the digestive tract, which allows the shape of your upper digestive tract to be outlined on an X-ray. Without the barium your upper digestive tract would be barely visible on X-ray.

Barium enema?
DefinitionBarium enema is a special x-ray of the large intestine, which includes the colon and rectum.Alternative NamesLower gastrointestinal series; Lower GI seriesHow the test is performedThis test may be done in a doctor's office or hospital radiology department. It is done after the colon is completely empty. Your doctor will give you instructions on how to empty the colon.You will lie flat on your back on the x-ray table and an x-ray will be taken.You will then be told to lie on your side. The health care provider will gently insert a well-lubricated tube (enema tube) into your rectum. The tube is connected to a bag that holds a liquid containing barium sulfate. It is placed in the rectum.The liquid is a type of contrast material that highlights specific areas in the body, creating a clearer image. The barium flows into your colon, and eventually passes out of your body with your stools.A small balloon at the tip of the enema tube may be inflated to help keep the barium inside your colon. The health care provider will monitor the flow of the barium on an x-ray fluoroscope screen, which is like a TV monitor.There are two types of barium enemas:Single contrast barium enema uses barium to highlight your large intestine.Double contrast barium enema uses barium, but also delivers air into the colon to expand it. This allows for even better images.You will be asked to move into different positions and the table will be slightly tipped to get different views. At certain times when the x-ray pictures are taken, you will hold your breath and be still for a few seconds so the images won't be blurry.The enema tube will be removed after the pictures are taken. You will be given a bedpan or helped to the toilet, so you can empty your bowels and remove as much of the barium as possible. One or two x-rays may be taken after you use the bathroom.How to prepare for the testYou must completely empty your bowels before the exam. This may be done using an enema or laxatives combined with a clear liquid diet. Your health care provider will give you specific instructions. Thorough cleaning of the large intestine is necessary for accurate pictures.How the test will feelWhen barium enters your colon, you may feel like you need to have a bowel movement. You may also have a feeling of fullness, moderate to severe cramping, and general discomfort. Try to take long, deep breaths during the procedure. This may help you relax.Why the test is performedThe barium enema is used to detect colon cancer, although it is used much less often than in the past.It may also be used to diagnose and evaluate the extent of inflammatory bowel disease (IBD) or other bowel disease.Normal ValuesBarium should fill the colon evenly, showing normal bowel shape and position and no blockages.What abnormal results meanAbnormal test results may be a sign of:Acute appendicitisColitis due to Crohn's diseaseColorectal cancerColorectal polypsDiverticulitisTwisted loop of the bowel (volvulus)Ulcerative colitisOther conditions under which the test may be performed:Hirschsprung's diseaseIntestinal obstructionIntussusceptionWhat the risks areThere is low radiation exposure. X-rays are monitored and regulated to provide the smallest 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 x-ray risks.A more serious risk is a perforated colon, which is very rare.Special considerationsColonoscopy is another way to diagnose and monitor diseases in the colon.ReferencesBresalier RS.
