Gadolinium contrast media (sometimes called a MRI contrast media, agents or 'dyes') are chemical substances used in magnetic resonance imaging (MRI) scans. When injected into the body, gadolinium contrast medium enhances and improves the quality of the MRI images (or pictures).

Is MRI gadolinium safe?

Use of gadolinium-based contrast agents (GBCAs) for MRI enhancement is useful in some instances and has been considered safe in most cases. Gadolinium is currently the only heavy metal suitable for MRI enhancement.

What are the risks of gadolinium?

The most common side effects include injection site pain, nausea, itching, rash, headaches and dizziness. Serious but rare side effects such as gadolinium toxicity and nephrogenic systemic fibrosis, or NSF, are most often seen in patients with severe kidney problems.
