computed tomography
"Orange flavor wasn't bad but a little orange food coloring might have made the illusion a bit more convincing.  Medium thick but went down without much problem. Technician assured me it was light years better than the chalky mix they used to use.  Then got an injection of an unnamed diuretic and urination every 5 minutes began. Not sure if it was completely the diuretic or the barium was a contributor but it continued right up to PET time. I warned them so they procured a plastic urinal and wrapped an diaper around me on the table. Neither got used during the 15 minute scan but it took a lot of clenched sphincter action to prevent a mess. Ten seconds off the table the urinal got used."
