Barium Sulfate: How It's Used in X-Ray Imaging of the Intestines

The compound used to produce X-ray images of the intestinal tract is barium sulfate. It is a white, powdery substance that is mixed with water to form a milkshake-like solution. When this solution is drunk, it coats the lining of the intestines and absorbs X-rays, making them visible on X-ray images. Barium sulfate is safe for use in adults and children and does not cause any side effects.
