Why is gastrografin used sometimes instead of barium sulfate?
If perforation of the GI tract is suspected, a water-soluble, iodinated contrast agent such as diatrizoate (Gastrografin) is used instead of barium because of the high mortality rate from barium peritonitis. Water-soluble agents are quickly resorbed through the peritoneal surface.
Is Visipaque water soluble?
Iodixanol is a dimeric, isosmolar, nonionic, water soluble, iodinated x-ray contrast agent for intravascular administration.
Why is barium not used in CT?
Suspensions created for CT use are very low density. Due to its insolubility in water, barium sulfate contrast media are supplied as fine particles of the barium sulfate suspended in water. Often artificial flavourings are added to make the mixture more palatable.
Why is Gastrografin used?
Gastrografin is a contrast medium (a dye) which contains iodine. It is used to clearly show on X-rays the area of your body that your doctor wants to investigate. This will be your gullet (oesophagus), stomach or intestines (gastrointestinal tract).
What is Visipaque used for?
VISIPAQUE is used to improve the clarity of X-ray images of the internal organs of the body by increasing the degree of contrast of different structures within the body. VISIPAQUE is used to study the heart, veins and arteries in the body’s circulatory system and the urinary tract.
Is barium a toxic contrast agent?
Chemically pure barium sulfate is nontoxic to humans, due to insolubility, and is frequently used as a contrast agent in the X-ray diagnosis of colorectal and upper gastrointestinal examinations.
Is Gastrografin an oral contrast?
GASTROGRAFIN is a palatable lemon-flavored, water-soluble iodinated radiopaque contrast medium for oral or rectal administration used Fluoroscopically to examine segments of the gastrointestinal tract and as an adjunct to contrast enhancement in Computed Tomography (CT) of the abdomen and pelvic anatomy.
Who should not take Gastrografin?
2. What should I know before I am given GASTROGRAFIN? Do not use if you have ever had an allergic reaction to GASTROGRAFIN or any of the ingredients listed at the end of the CMI. pregnant or plan to become pregnant or are breastfeeding.
What is the difference between high and low osmolar contrast?
The structure of iodinated contrast media. High-osmolality contrast media (HOCM) have an iodine to molecule ratio of 1.5 : 1. Low-osmolality, nonionic contrast media (LOCM) have an iodine to molecule ratio of 3 : 1. Isosmolar (isoosmolality) contrast media (IOCM) have an iodine to molecule ratio of 6 : 1.
