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).
Advantages: Lower absorbed dose so can use higher concetration resulting in quicker uptake for scan, cheaper to make, better efficiency in imaging. Preferred when quicker imaging is desired or when the patient is taking iodine uptake blocking agents (i.e. iodinated contrast).
