I hate to burst everyone's bubble, but this is just MRI with a new and different kind of tracer.
There will likely be some great clinical applications from this, but it's not a game changer. It needs a big, expensive, superconducting magnet.
It's also not radiation free (just like MR). It's just ionizing radiation free.
Obviously when they say "radiation free" they mean "ionizing radiation free". The term "electromagnetic radiation" includes things like radio waves and visible light, not just high energy ionizing stuff like UV, x-rays, and gamma rays. Literally everything emits some amount of non-ionizimg radiation. Non ionizing EM is pretty harmless unless you have enough of it to cause heating/burns.
I wasn't speaking to people like you when I explained radiation. I was speaking to everyone who can't distinguish this from magic. You'll also have to understand that tissue heating is a concern in some instances, as is "running around in a large magnetic gradient". (Guess what happens?)
Vogel has something to sell. The whole article explicitly uses words that the lay public will misunderstand to attract attention in the popular press. This whole article is a puff piece. It's based on real science, but it is not intended to give the reader an accurate picture of what he's selling.
There are small MRs that you can move on the back of a semi or keep in a room adjacent to an OR. That's what he's saying when you translate this statement into something that remotely resembles the truth.
