What is ioversol injection?

Ioversol injection is an iodine-based liquid called a contrast agent. It is used for X-ray imaging scans to reveal detail in the body's interior structures, such as blood vessels or head, which would not normally show during an X-ray without contrast. Sold under the brand name Optiray, ioversol is administered by injection prior to an X-ray scan. Although this contrast agent is often called a "radiopaque dye," it does not actually dye any internal tissue a different color. It is opaque to X-rays and makes the tissue where it is located appear white on the image as a result. This allows the doctor to see details in the image that would not otherwise be visible. Soon after the X-ray, the ioversol is excreted from the body primarily in the urine.
