Whenever I have had CT scans I have to drink a barium solution that is lighter than the usual barium. They usually mix it with fruit juice so its not too bad. I don't remember how much, its like one of the hospital pitchers full I think. Then when they get you in the CT room, they start and IV and put contrast thru the IV and then take the pictures. I would think you will be in and out in about a hour or so. I usually have always taken my meds with just a sip of water the mornings of my tests. Hope that helps.
