Me. MRI. No way. Thought I could do it. Put my head in the basket, noise-blocking headphones, started the slide into the tube. Got a little freaked as they slid me in but I was okay as long as I could feel the edge of it. Tech said "just a little further," and at the point I could no longer feel the edge, I started crazy weepy boo-hooing and had to be pulled out. What the hell? Had this experience? Makes me shudder to even think about doing it again.
