What is Gadolinium?

Gadolinium is a heavy metal that is used as a contrast agent (“dye”) to enhance the quality of the images obtained during an MRI or MRA scan. It is injected into the patient’s vein during the scan procedure.

Gadolinium contrast is supplied under various names.

These include Ablavar®, Dotarem®, Clariscan®, Omniscan®, MultiHance®, Magnevist®, Eovist®, Magnegita®, Gado-MRT®, ProHance®, OptiMARK®, Primovist, Gadovist®, Gadavist®, Magnetol®, and others.

Is Gadolinium Dangerous?

Gadolinium is highly toxic. When used as a contrast agent, it is chemically attached to a substance known as a “chelator”, intended to quickly remove the gadolinium from the body following the scan.

Recent scientific research shows that significant amounts of gadolinium stay behind and accumulate especially in the brain and bones. This poses enormous potential health risks. Some gadolinium products are more likely to be retained in the body than others.
