The oral contrast drink is for patients who are having for a stomach/bowel CT scan. The barium-based drink essentially “enhances” the gastrointestinal tract so it can be better defined on the CT images.

Oral contrast is used to image the stomach and intestines. It is a very dilute, flavored barium solution that you drink approximately 1 hour prior to an examination. Intravenous contrast is sometimes referred to as "dye". Although colorless, it contains iodine, which makes specific organs, blood vessels, and tissues visible on x-rays for better detection of disease or injury. It is not radioactive.

The purpose of oral contrast is to make certain organs or tissues more recognizable during radiological procedures. Virtual colonoscopy uses oral contrast to mark stool remaining in the colon. This helps the radiologist differentiate between stool and other abnormalities in the colon. It is very important that this medication be taken in its entirety to get the best possible results. If not taken properly the exam may have to be repeated. See similar questions...

Contrast ratio is the ratio of luminance between the brightest white and the darkest black of a particular device or a particular environment. Projected cinema film, or a photographic reflection print, has a contrast ratio of about 80:1. Television assumes a contrast ratio, in your living room, of about 30:1. Typical office viewing conditions restrict the contrast ratio of a CRT display to about 5:1. See similar questions...

Plain (without contrast) CT abdomen , bowel loops are difficult to differentiate from adjacent normal or abnormal structures because of similar density. Oral contrast media (iodine solution) is hyper dense .so once contrast solution is taken before (according to protocol) ,all bowel loops are filled with hyper dense solution. So it is easy to differentiate bowel loops from adjacent normal or abnormal structures. See similar questions...

Intravenous contrast is used in CT to help highlight blood vessels and to enhance the tissue structure of various organs such as the brain, spine, liver and kidneys. "Intravenous" means that the contrast is injected into a vein using a small needle. Typically the contrast is loaded into a power injector, which injects the CT contrast using tubing through the needle into the body during a specific period in the CT exam. See similar questions...

This substance is given to highlight various body parts and is eliminated in a day or two. It is usually given by mouth or injection. It is normal to feel a warm sensation as the dye makes its way through your body. See similar questions...

Contrast is the term used for the material that is injected intravenously into a vein in your arm or hand. It is used to enhance the visibility of certain tissues or blood vessels. Few adverse reactions are reported with MRI contrast. See similar questions...

Oral chelation involves the ingestion of natural chelating substances. Various vitamins minerals amino acids antioxidants phytonutrients and herbs can be used to supplement the benefits of the numerous chelating agents. The addition of these substances helps to replenish any loss of nutrients that may occur during the chelation process. In so far as possible all ingredients are derived from natural sources.

When a reporter or author writes a story, article or book, he/she will investigate the material. He will interview people, record what her sees and may report on previous written information found in books, journals, letters. Interviewing people create a live report of the story. It is an "oral" report of an event. An oral history is the same thing. It is the documenting of history through what people remember and tell to a reporter/recorder. See similar questions...

Acid reflux disease, also known as gastroesophageal reflux disease (GERD) is a fairly common affliction. It is characterized by bouts of intense heartburn or a burning sensation in the back of the throat. Zenith 42 Plasma HDTV sets, also known as plasma HDTV displays have been obtainable for several years; however, they are more popular than ever today. find articles | submit articles | link to us | site map | terms of use | privacy policy | contact us | advertising | partner with us See similar questions...

Allergies to shellfish or iodine need to be pre-medicated before you are injected with contrast media. Tell your doctor about your allergies. You will be asked again about any allergies before you have a test that involves taking contrast material and the technologist or nurse will make sure you are pre-medicated. See similar questions...

Not all CT examinations require the use of a contrast agent. When a contrast agent is required, it is because the radiologist and referring physician determine that it is necessary for diagnosis. Contrast agents are considered to be safe and side effects are uncommon. The benefits associated with the improved imaging of particular organs generally outweigh the low risk of allergic reaction. See similar questions...

Sometimes your Doctor will order a CT scan "with contrast". This means a trained CT Technologist will insert a thin, plastic IV catheter into a vein, usually in your arm. The contrast will flow through this catheter into your arteries and veins to highlight them and give the Radiologist a more detailed study. Most patients feel some degree of warmth and get a salty taste in their mouth as the contrast is flowing through their blood vessels. These sensations last for just a few minutes See similar questions...

SpikeNet’s algorithm is designed to be extremely good at detecting objects even when the contrast in the image is very low. One problem that this can cause is that in an image where the only interesting objects are at high contrasts, unwanted detections may occur in regions of very low contrast. To avoid detecting details which are not relevant, you can raise the Minimum Contrast value that is normally fixed at 0. See similar questions...

Yes. While most runners and cyclists know the importance of hydrating, some don't realize over-hydrating can dangerously lower blood sodium levels-a condition known as hyponatremia. Hyponatremia seems most common in female and beginning marathoners and triathletes for two reasons. One, they are on the race course for many hours, losing lots of sodium in sweat. Two, they are hypervigilant about staying hydrated. See similar questions...
