When a doctor orders an MRI, patients typically trust that the procedure is safe and necessary. However, recent research now indicates this routine diagnostic test could actually have severe consequences for your health. And it all comes down to one metal – Gadolinium.
The Metal That Never Leaves: What You Need to Know about Gadolinium
Gadolinium is a metallic element injected into approximately one third of MRI patients to enhance the imaging. If you’ve received an MRI with “contrast,” you’ve been exposed to gadolinium. The problem with this is that gadolinium is a known neurotoxin.
It was believed that due to gadolinium being bound to other molecules, it would be quickly excreted through urine. However, research now shows that at least 1% of each dose may be released from its bonded state and deposited in the patient’s brain, bone, and other bodily tissue.
If you have kidney disease, this can result in nephrogenic systemic fibrosis, a potentially lethal condition. But even without kidney disease, the outcomes can be disastrous.
The Real-Life Impact of Gadolinium
In 2013, Gena Norris, wife of actor Chuck Norris, underwent three MRIs in one week to evaluate her rheumatoid arthritis. In the years that followed, Gena experienced a range of mysterious health issues and symptoms of gadolinium deposition disease. Even after years of treatment, Gena has not fully recovered from the effects of the Gadolinium.
The International Response and the FDA
In 2017, the European Medicines Agency’s Pharmacovigilance and Risk Assessment Committee (PRAC) conducted a year-long review of gadolinium’s risks when used in MRIs. As a result, they recommended to suspend the marketing authorizations of four gadolinium-based contrasting agents (GBCAs), because of “convincing evidence of accumulation of gadolinium in the brain” and harmful tissue impact.
In contrast, the US Food and Drug Administration (FDA) stated in 2015 that they would study the adverse effects of gadolinium further, but have not made any public safety announcements since then. They did, however, vote in September to add more warnings to GBCAs.
Staying Protected
If you suspect that unexplained symptoms you’re experiencing may be linked to retained gadolinium from a contrast MRI, file a MedWatch Adverse Event Report with the FDA. Remember that you have a choice when it comes to contrasting agents in MRIs. If you’re in need of an MRI, inquire about your options and consider asking for a ‘stable cyclic’ agent in place of linear gadolinium.
Chelation therapy, which is designed to help pull metals from the body, is recommended by some healthcare providers but others believe it may not help enough. You can also look into support groups for individuals dealing with gadolinium toxicity for more tips and guidance.
It’s important to stay informed and question procedures that involve injecting substances into your body. Ask questions and do your research to ensure that you’re making the best possible decisions for your health.
