Local Tissue Toxicity in Response to Extravascular Extravasation of Magnetic Resonance Contrast Media

Abstract

The risk of tissue damage due to extravasation is not widely appreciated for the gadolinium chelates. Care should be exercised during contrast injection, to avoid inadvertent extravasation and its deleterious consequences, in particular with the two higher osmolar agents (gadopentetate dimeglumine and gadoversetamide).
