Forgive me, MRIs are amazing! You absorb a radiowave, then get time reversed with another pulse, then a time later you - your liver what ever - sends out a signal.  That is right you are being turned into a radio. What hurts me is people breaking laws of physics when they explain what is going on, some times leaving out that the make you into a broadcast walky talky that zomby like repeats what has been said to it. Podcast The video style will improve with time and work. (I certainly hope so!)
