"You can be brave", "there's nothing to worry about" do not work, because even brave people feel fear and there are things to worry about; those big clunk noises.

"It's a bit scary isn't it! Look, it's a big machine! It makes lots of loud noises, and you're in a little space. But it's an adventure!" changes expectations. You're allowed to have fear and express it. But you're allowed to enjoy it too.

> Just before the whirring and banging of the machine gets louder, the operator encourages young patients to listen closely for the moment that the craft “shifts into hyper-drive.” This reframing transforms a normally terrifying “BOOM-BOOM-BOOM” sound into just another part of the adventure.

This is addressed in the article; the "thunks" get incorporated into the MRI "adventure".

After dating a nurse and finding out about a bed that was just a bit too close to the thing getting sucked in.

Yeah, MRI's aren't exactly risk free "adventures".

Fortunately, most humans don't spontaneously generate ferrmagnetic materials.

Only Wolverine is at risk in that regard.

The only problem is if you are in between a metal object and the MRI machine however.

Unless you're planning on augmenting yourself like in Deus Ex I agree its not a big deal. But a big thing coming at you at high speed would ruin your day.

I can point you at a similar issue anywhere in a hospital. Hospitals are dangerous places when there's a misstep, which is why they spend so much time training on procedure.
