Isn't cool to imagine that while you're in that machine, a majority of the water molecules have their nuclear spins aligned? Something that would never happen in natural conditions. You don't feel different, yet there is something unique going on in your body for a brief moment of time.
I thought about that last time I had an MRI (alignment of proton spins)~~
All I could think of when I had an MRI is to try and not panic...
