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.
I think a really key difference is that you could make yourself comfy in your little nook, and you could leave it at anytime. Plus in your case it sounds like you went there to escape the noise. This place is the noise. Even if you have a full on panic attack, you physically can’t get out of that tube without the techs pulling you out. Having the choice and ability to leave a space is really important.
