What is Feridex I.V.?

Feridex I.V. (ferumoxides injectable solution) is a contrast agent used in magnetic resonance imaging (MRI) procedures to help check for lesions on the liver. Mostly comprised of iron, Feridex I.V. is administered intravenously prior to an MRI scan. It is absorbed into the reticuloendothelial system (RES), which is part of the immune system which is made up of monocytes and tissue macrophages located in organs throughout the body. Because the RES collects and stores excess iron from the bloodstream, Feridex I.V. can be detected by the magnetic fields and radio waves that are used in an MRI scan.
