[[1]]-sulfate is the most common contrast material taken by mouth, or orally. It is also used rectally and is available in several forms, including:
- powder, which is mixed with water before administration
- liquid
- paste
- tablet
Contrast materials can have a chemical structure that includes iodine, a naturally occurring chemical element. These contrast materials can be injected into veins or arteries, within the disks or the fluid spaces of the spine, and into other body cavities.
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.
