Milk would be cheaper too:
Researchers at St. Luke’s-Roosevelt Hospital Center in New York randomly assigned 215 patients undergoing abdominal or pelvic CT scans to drink whole milk or a barium beverage . . . Radiologists who didn’t know which drink the patients had swallowed assessed their X-rays. Turns out they couldn’t tell the difference by looking at the images.
