The white thing over my head is the camera that helped take the pictures of my brain. The tube running down my chest is part of the cord that had the head phones on it so I could listen to music during it. There was a ball that I held in my hand and I could squeeze it if I needed something. I accidentally squeezed it once and he said whats the matter and I said I accidentally squeezed it. the white things on the side of my head held my head still. I was in the MRI for about an hour. It was boaring because I only had a blue line to look at and I couldn't move.
