Contrast for MR Enterography

Can anyone tell me what kind of contrast to expect for an MR Enterography? I’m hanging one done at Mayo Jacksonville in a few weeks as we try to figure out why my ileostomy output has suddenly gotten out of control. I really struggle to keep down thick or chalky oral contrast. I plan to bring Zofran with me, but sometimes even that is not enough to keep from vomiting chalky or thick contrast agents.
