@elsie37, I moved your message to an earlier discussion about concerns of Gadolinium dye in MRIs. Click VIEW & REPLY in the email notification to see past posts that answer some of your questions.

Here is a statement from the FDA posted May 22, 2017
– FDA Drug Safety Communication: FDA evaluating the risk of brain deposits with repeated use of gadolinium-based contrast agents for magnetic resonance imaging (MRI) https://www.fda.gov/Drugs/DrugSafety/ucm455386.htm

- Mayo Clinic Finds Direct Evidence of Gadolinium Deposition in Brain Tissues Following Contrast-Enhanced MRI Exams https://newsnetwork.mayoclinic.org/discussion/mayo-clinic-finds-direct-evidence-of-gadolinium-deposition-in-brain-tissues-following-contrast-enhanced-mri-exams/

I'd also be interested in hearing from others and repeat your excellent questions here:
"For those of you getting annual MRIs, have you changed your routine? Has your doctor suggested reducing the annual procedure? Are you concerned about the effects of the dye on your brain? Is there a substitute procedure that provides equal levels of screening as MRIs? If you have been relying on MRIs for early detection of breast cancer because you are at high risk, has this made you more likely to want a prophylactic bilateral mastectomy?"
