Hopefully the Zofran kicks in and stops the vomiting from the contrast. I remember when I had the MRI Enterography and they injected me with a drug they said around 50% of patients get sick from. They brought out a vomit bucket, which really warmed the cockles of my heart. The drug was called glucaphen, or something like that. It slows down the bowels and they take another set of images after it kicks in. I was a little freaked out by it especially because when you are inserted in the MRI tube there is no access to the vomit bucket, so that if there is a sudden wave of nausea there is a good chance of vomiting on one's self as there is no place to go inside the MRI tube. Fortunately this did not happen, as I actually did not get sick from the contrasts on the CT or the MRI.
