Protocol for CTC

What is the protocol for CTC?

The typical preparation for CTC involves a combination of a low residue diet, cathartic bowel preparation, and fecal tagging (i.e., labeling of fecal residue) using both barium sulfate (Tagitol) and water-soluble iodinated contrast material (Gastroview). When CTC is performed on the same day as an incomplete OC, Gastroview is administered after sedation has worn off and 2 to 3 hours prior to scanning.
