Several years ago I was ordered to have an MRI for a large hematoma on my leg. They put me in the tube and as it started to go in I realized just how cramped it was going to be - both arms went up and I pulled myself out. Think I startled the technician. Thankfully he decided I didn't need to go all the way in and left out my head, shoulders and arms. Frankly it's all bad. I used to like CAT scans but tomorrow am having me and just before must drink 30 oz of a chalky barium fluid. Well that'll take the joy out of it for me.
