The X-Ray Contrast Dye You Can Drink

Doctors often use a specialized iodine compound called Diatrizoate to see inside the body. Surprisingly, this liquid can be safely swallowed or administered rectally to highlight your digestive tract on an X-ray.

While most people associate medical dyes with intravenous needles, this versatile substance behaves differently depending on how it is delivered. When swallowed, it coats the interior of your gut, allowing radiologists to track potential blockages or tears that would otherwise be invisible. It is essentially a map-making tool for your internal organs. It is truly remarkable that a single chemical can be used for everything from vein imaging to gastrointestinal diagnostics.
