Isisman, I’m sorry to hear the problems with your husband’s CT-scans. I’ve had quite a few CT-scans (I’m a CC survivor), but fortunate in that the procedures haven’t been a major problem for me. They always give me a thick liquid barium to drink. I’m able to tolerate it pretty well. I just feel bloated afterwards.
But I wanted to mention. During one of my scans, they said I could try another type of barium (I don’t remember the name though). But it was more a clear/liquid kind of drink. You mixed it with orange juice, I seem to remember. They told me that “drink” was supposed to be gentler on the stomach.
Does your husband vomit from the barium, or from the dye? If from the barium, you may want to ask about this clear/liquid kind of drink, and see if that helps.
