What are Contrast Agents?
Contrast agents are colourless liquids that are usually injected into an arm vein.
The most commonly used contrast contains iodine in a special compound which shows up clearly on X-rays or CT images. This is used to show blood vessels, kidneys and other organs more clearly.
At NRL, we use Omnipaque for most procedures that need contrast. Omnipaque is one of the safest contrast agents available. MRI scanning requires use of a different contrast, containing gadolinium. At NRL we use Magnevist and Multihance.
