Including the ones in your brain.

It was a brave engineer who put themselves into the first one to test it.

While I agree with the thought that the engineer was brave to get in there, it had already been tested extensively under its alternate name NMR to determine molecular structures. People get scared when its called Nuclear so for people they changed its name to MRI.
