I had a CT Enterography done about a month ago. I did some reading about the test ahead of time and found there have been some studies done on drinking milk in place of the oral contrast and that patients tolerated the milk better and the results were very consistent. I did not have the luxury of drinking the milk, but I will tell you I would have preferred that over the oral contrast ANY day. I have a really hard time with the contrast.
Good luck with your test! I'm having my 4th CT scan in less than a month on Thursday and will be drinking the yucky contrast.
