My MRIs usually take 45mins-1 hour. Brain and neck. With and without contrast.
I match the beats of the machine with a sound from a band. The tunes vary. Some Pink Floyd, Megadeth, AC/DC, Metallica ...
But, you could match the sounds to other sounds out there...
I just have to be careful not to tap my toes or fingers to the beat. That would just make the scan even longer in the tube
Take a deep breath, in and out.
Close your eyes and enjoy the ride. Doesn't last long. You'll be fine.
