The iodine moiety of diatrizoate is not penetrable by X-rays, therefore it blocks the X-ray film exposure by radiation. This makes it possible to distinguish, on X-ray film, body parts that contain diatrizoate meglumine from body parts that do not contain this agent and allows for visualization of different body structures."}]
