the original was closer to my understanding of MRE than your description based on "the explanation the MRI tech told me once."

I think you would lose your bet.

MRI creates a very strong magnetic field, and then turns it off. When the field is ON, all the molecules line up. When the field is thrued OFF, all the molecules relax. The relaxation represents a change from a higher energy state (maintained by the magnetic field) and a lower energy state. The excess energy is radiated and sensed...and then turned into images.

"transistors and batteries" are not required to emit energy in the form of radio waves!
