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.

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

∙ 12y agoI hope you mean 'Barium Enema'. It is an inert substance injected into the anus to assist in viewing the function of the bowel for the purpose of assessing whether bowel cancer or pollyps exist. It allows the organs to be wiewed more clearly in X-Rays. Barium Swallows or Meals are also used to assess digestive conditions, such as reflux

Why is barium sulfate used in xray diagnosis of gastrointestinal system?
The practice of clinical diagnostic radiology has been made possible by advances not only in diagnostic equipment and investigative techniques, but also in the contrast media that permit visualisation of the details of the internal structure or organs that would not otherwise be demonstrable.There are numerous types of contrast media which have different applications, depending on their differing chemical and physical properties. Radiological contrast media are usually water soluble solutions, but there is one commonly used variety that is based on a suspension of large insoluble particles. This is the barium sulphate mixture that is used for barium meal and barium enema examinations of the upper and lower gastrointestinal tracts. Barium sulphate suspensions have better coating properties than the iodinated contrast media, and tend to form thin layers spread over the lining of the gut.surMe
Which is more basic Mgo why.?
the answer is BaO..... because the barium is occupy the lower position than the magnesium.....in the same group......... the the alkalinity of the barium oxide is slightly higher than the magnesium oxide.................
Is barium an ionic bond?
No. An ion is a positively or negatively charged atom, or group of atoms due to more or less electrons than necassary. Both barium and sulfate are ions, but together they are a compound, not an ion. Barium Sulfate is a chemical compound made up of two ions, a barium ion and a sulfate ion. A Barium ion is Ba+2, meaning it has two less electrons that a barium atom has. The reason for this is because the barium atom has 56 total electrons. Every atom wants to be ion with a filled valence shell, that is to have the same or similar electronic configuration of a noble gas (the elements in the right most column). The valence shell is the outermost shell of electrons and for barium the other shell is 8 electrons. In order for Barium to do this, it has to somehow lose 2 electrons to become similar to Xenon's electronic configuration. Sulfate, SO4 -2, is also an ion. the -2 means it has aqcuired 2 more electrons from another ion. It got those two electrons from the barium atom, simultaneously making the barium atom a barium ion. Sulfate is called a polyatomic ion, meaning an ion made up of more than 1 atom. When the barium ion gives the sulfate ion two electrons, thus making both electronic configurations "happy" they bond together to make an ionic bond, creating the compound barium sulfate.
Barium element is larger or smaller than caesium?
Barium is smaller than Cesium
Is barium smaller than aluminum?
Barium (137.327) is larger than aluminum (24.305)
Is the electronegativiy of barium larger or smaller than that of strontium?
The electronegativity of barium is less than that of strontium.
What is the best day to have a colonoscopy?
No particular day is any better than any other for having a colonoscopy.
Does calcium and barium have similar or different reactivities?
Calcium and barium have similar reactivities, because they are both alkaline earth metals. Quantitatively, barium is slightly more reactive than calcium because it has more electron shells between its valence electrons and its nucleus.
What is barium's chemical formula?
Barium is an element, it has no chemical formula other than 'Ba'.
Is iodine -131 a more stable than barium -137?
Iodine 131 has a half-life of 8.0197 days. Barium has no half-life. So no, Iodine-131 is not more stable than barium-137.
Is barium higher than strontium?
Strontium
Does beryllium or barium have a bigger atomic radius?
Radium has a much larger atomic radius than beryllium.
Why does beryllium chloride has more covalent character than barium chloride?
As beryllium is smaller than barium and it is more polarising, it will distort the perfect ionic sphere and attract some outer shell electrons of barium and give it a covalent character.

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.
