You don't operate an MRI outside of the designated specifications IF you want to actually use it for medical diagnostics, and IF you want accurate results.
In the early 1990s I was a reporter in a small town when the local hospital got its first MRI machine. IIRC the warm up period for that particular model was almost two hours.
If you tried using it before that, you didn't get anything that was usable, so the machine was generally powered 24x7x365 except when it was down for servicing and calibration.
