Alright, did some research, first off you’re wrong about this being the reason even if this was a plausible reason. The real reason is the ash and heat divertors failed.
Second, you don’t even need liquid helium for super conduction. Here’s a few closed loop helium gas coolers that get to 10 kelvin. They need to be refilled on the scale of years, not from a single test.

I get you care deeply about helium loss but this is the last thing you should be accidentally spreading misinformation about. This process literally creates more helium then it uses.
A single use of an MRI doesn’t use 2000 liters, that is the upper end of a hospitals ENTIRE supply of helium. On average an MRI users 70 Liters per MONTH of operation. You’re literally just spewing bullshit at this point, have a fun time being completely misinformed on things that upset you greatly, I’m going to go play games
