MRI machines need thousands of liters of liquid helium to function. Health care workers say they can’t afford any disruptions to the helium supply chain.
Helium doesn’t freeze because quantum mechanics. gestures furious
That means liquid helium can cool stuff to temperatures where nitrogen would be solid. This is used on the superconducting magnets in MRIs.

Helium can be cold enough for MRI yes. But the way its reported makes it seem that helium is always cold, which is not true.
If you treat Helium right he remains pretty chill. But if you wrong Helium, Helium gonna get cold as ice.
Helium is right behind you
Sure, but they’re right that is the only elements that works for this purpose.
“remains liquid at cold enough temperatures” != “the element is cold enough”
I bet it is frozen at 0 K
