Since my cancer diagnosis in June 2002, I have had CT scans every few
months, each of which was preceded by three tall cupfuls (or were
they cupsful?) of the barium drink, and my last couple of PET scans
were as well. The standard term the staff use is "barium milkshake"
(no thanks, make mine vanilla). It does taste somewhat odd and not
unchalky, but I'd sooner down a couple of gallons of it (ideally not
at one sitting) than one small bottle of Fleet PhosphoSoda, which I'm
sure a number of you have experienced as the prep for colonoscopy.
Uggh. In the CT scans, I'm always hooked up to an IV (either through
my chest port or the standard access via a vein in my arm) through
which some dilution of iodine is administered. That yields a not
really unpleasant but hard to contextualize taste of potatoes and a
warm feeling in the throat. (I'm not a fan of anisette, pastis,
Ricard, Pernod, or other licoricey drinks, but I never associate
either the iodine IV or the barium milkshake with that flavor.)
