Gadolinium, a contrast agent used in MRIs, is toxic and accumulates in the brain, tissue, and bones. The FDA issued a black-box warning about it in 2018. MRI is mainly a visual tool for radiologists, not a functional imaging technology.

For the people who aren't able to maybe use that contrasting substance and the fact that it's even a toxic one to begin with. The scanning technology itself, and then there's additional components that are adjacent but included in the implementation of a scan.
So gadolinium is a toxic, heavy metal that should not be in the body. And then in 2018, the FDA put a black box warning on it, because we find out it's accumulating in the brain and tissue and bones of every healthy person that's getting it. And so they're actually, at the same time advocating for a new solution. The real issue here is that mri, with or without that contrast agent, is just a quality qualitative scan. So the images look nice. We see all these pictures of the brain, and that's amazing. And we hear about FMRI, and we might have some idea that this machine can do something more useful, but it can't. It's really so limited to just a visual inspection of what a radiologist can do.
