Oh, stop arguing about what a CT scan is or isn't, you big babies. They laid me down (the ceiling was decorated with backlit photos of blue sky and blossoming branches), stuck me in the donut-shaped thing, injected me with dye, told me to hold my breath a couple times and scanned me. In all, it took about 10 minutes in the door and out again.
Now I have to drink a lot of water so I can pee the dye out. Yay.
