My father complained about that too. I knew why the gradient coils were 
making their noise, so it didn't worry me.

Getting through the whole procedure takes a lot longer than that. My 
local hospital is only a ten minute walk away, but the hospital insists 
on keeping me sitting around for about an hour during even the fastest 
procedures. They seem to need to keep the patients intimidated. Or at 
least acting as if they are intimidated.
