- Question: After surviving for sixteen years with no regrowth, I have been told by my neurologist that I should switch from annual MRIs to having one every other year. For peace of mind, I would prefer annual MRIs, but am concerned about the gadolinium, which I am told contains "heavy metal", and can be dangerous. With this in mind, would you recommend the less frequent MRIs?
There is no consensus on the question of 'how often'. Your neurologist's
recommendation is reasonable.
I am not aware of any cumulative toxicity from the gadolinium.
