What is Magnevist?

Magnevist (gadopentetate dimeglumine) is a contrast agent that has magnetic properties. It is used in combination with magnetic resonance imaging (MRI) to allow blood vessels, organs, and other non-bony tissues to be seen more clearly on the MRI.

Magnevist is used to help diagnose certain disorders of the brain, blood vessels, and spin (central nervous system).

Magnevist may also be used for purposes not listed in this medication guide.
