DESCRIPTION: DEXEDRINE (dextroamphetamine sulfate) is the dextro isomer of the compound d,1-amphetamine sulfate, a sympathomimetic amine of the amphetamine group. Chemically, dextroamphetamine is d-alpha-methylphenethylamine, and is present in all forms of DEXEDRINE as the neutral sulfate.
Types of tests that nearly always use ICCM include angiograms/angiography (which are X-rays of blood vessels), arthrography (which is an X-ray of the inside of a joint (like the shoulder)) and myelography (which involves injection of contrast medium into the fluid around the spinal cord).
Barium-sulfate is the most common contrast material taken by mouth, or orally. When iodine-based and barium-sulfate contrast materials are present in a specific area of the body, they block or limit the ability of x-rays to pass through. As a result, blood vessels, organs and other body tissue that temporarily contain iodine-based or barium compounds change their appearance on x-ray or CT images.
