I’ve had scans for my brain and neck area and they’ve used a cage always. And the last time they did the neck they did this extra big cage just for that section. It fucking sucks. It’s possible it’s just because I’m in a red state that hasn’t had as much investment in it for medical tech so things are more outdated. Or the people hate me and want me to suffer in that cage. Probably that first one. Or they just need to because they’re scanning the whole brain maybe? I dunno. I just know that I have them put a washcloth over my eyes so I can’t see it because, like you said, nightmare fuel.
