Would they spin anywhere near that fast in use? I don't see any reason why they would.
Spinning wheel of death? More like a spinning wheel of life, since they can detect problems early enough to save lives.
I think that MRI has more extreme stuff than CT. I`ve just watched a video in which they strapped metal objects to a strain gauge to measure how strongly the MRI magnet attracted them. A spanner inside the MRI scanner "weighed" 500 lbs. The magnetic field of an MRI scanner is extraordinary.
Noisy things, too. Having an MRI scan has been likened to listening to dubstep :) Even with the hearing protection they give you, it`s very much audible.
I found it a bit chilly after a while. Extreme cooling is needed for the superconductors and no insulation is perfect.
But while these scans are a bit unpleasant, they`re a lot less unpleasant than some of the results of not having them.

"Lying!" It's like lying in a spinning wheel, etc. "Laying" means putting something on something, like a hen laying an egg, or laying a photo album on the coffee table. You may LAY your head on a pillow, but you LIE down when you do! I swear 88% of people have no idea of this.
