I am a 22 year old male. I want to know why do you have to drink iodine before a CT scan?

it opacifies the bowel and is good for looking for bowel disease. you can drink barium instead of iodine if you are allergic.
You do not “have” to drink iodine for a CT. Iodinated contrast materials are given by mouth at some centers in liquids so that the swallowed material will be dense enough to be seen
within the examined lumen of stomach, small or large bowel as white material. Depending on the goal of the CT examination, the radiologist or the radiology group may not need an iodinated contrast filled stomach and/or bowel. Some groups use water as a substance to drink to allow the stomach and duodenum to be evaluated with water appearing not dense or white, but rather gray to black easing visualization of the bowel walls.

To opacity your stomach and your intestines so we can see inside them better.
