What kinds of CT contrast are used?
University MRI uses both Oral and IV (intravenous) CT contrast. 1. Oral Contrast: Oral contrast consists of two 16 oz. bottles, which are kept refrigerated prior to ingestion. Most commonly we offer a Mixed Berry flavored contrast, however there may be times when we also have Banana, Orange, or plain unflavored contrast available. Oral contrast consists of liquid barium, and must be ingested at least one hour prior to the start of the CT scan; this oral contrast helps make the intestinal tract visible. There are no side effects from the ingestion of oral contrast. Oral contrast is thicker than milk, but thinner than a milkshake; it is creamy, and slightly chalky. Patients receiving oral contrast are scheduled at least 1 hour and 15 minutes prior to the start of their exam to allow them time to drink the contrast, and time for the contrast to be absorbed.
