Who Is This For?

Patients
Experiencing new or puzzling symptoms after MRI contrast

Doctors and healthcare professionals
Seeking to better understand and support patients with complex post-MRI symptoms

Interested in emerging patterns and hypotheses around gadolinium retention

Journalists and media
Covering medical safety, patient advocacy, or public health
Why This Matters
For many, the long-term effects of gadolinium contrast agents are a mystery. This patient-led survey, featuring the experiences of over 300 individuals, including 185 with laboratory-confirmed gadolinium retention, offers a unique window into the real-world challenges and patterns emerging after contrast-enhanced MRIs. While this report cannot prove causation, it highlights critical associations and signals that deserve further attention.
If you are a medical professional watching this, you are likely sceptical. You should be. You rely on GBCAs to diagnose cancer and MS. We aren't asking you to stop diagnosing. We are asking you to look at a new toxicological pattern that matches the FDA's 2015 admission of retention.

No, this report is observational and cannot, on its own, establish causation. Instead, it is hypothesis-generating—meaning it identifies patterns and associations that suggest a possible link between gadolinium-based contrast agents and the symptoms reported by patients. When considered alongside other scientific research on gadolinium toxicity, these findings contribute to the broader body of evidence used in frameworks like the Bradford Hill Criteria, which help evaluate whether a causal relationship exists. Importantly, our survey highlights urgent areas where more research is needed, as the signals we found suggest that many patients could be experiencing harm from contrast agents without adequate recognition or support. This underscores the need for further investigation and greater awareness among clinicians and regulators.
What support resources are available for people affected by gadolinium toxicity?
There are growing online communities, patient advocacy groups, and support forums dedicated to those experiencing symptoms after gadolinium-based contrast MRIs. You are not alone, and support is available.
How can I get personal support or guidance if I think I’m affected by gadolinium contrast?
