Apparently this was done because air captures less X-rays than CSF and thus creates more contrast with brain tissue compared to the cerebrospinal fluid.
Unfortunately this was pretty painful and uncomfortable.

Everyone’s experience is different. When I got an MRI scan I really did almost fall asleep. Yes it was loud but its rythmic tapping almost sounded like a song, and add the warm blanket on my legs I was sometimes almost nodding off (it was for a cognitive study so I had to stay awake)
