I have had about 3-4 of those CT's in the past year while in the ER. That type of contrast is so much better and so much easier to get down too. Seems thats all my ER uses, thank goodness! Everytime I get them (usually for obstructive symptoms) I almost always throw about half of it up, but always am still able to have the test. So much easier,
I am a technologist. I do ct's and xray exams.
Gastrographin or gastroview is the contrast in question. It can be mixed for use in
ct or regular xray exams. This mixing information and dilutions are included with the
bottle/box it comes in and can be tailored for most any ct or xray exam where contrast is needed.
If you don't like the barium, refuse it and ask what alternative is available at the imaging center.
Another, and I believe, better alternative available now is Omnipaque oral. Omnipaque oral mix is
not oily like the Gastroview and causes much less stomach upset.
