the only element on Earth cold enough to make an MRI machine work.

I didn’t know that elements had a defined temperature. Bang up reporting there, NBC.

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.
