Diatrizoate sodium is a contrast agent used in medical imaging techniques. It is a member of a group of drugs known as radiopaque contrast agents, which are substances that improve the visibility of specific bodily fluids or structures during diagnostic imaging. X-rays, CT scans, and angiography are the main radiographic exams for which diatrizoate sodium is employed. Depending on the specific operation and the location of the body being studied, diatrizoate sodium can be given orally or via injection. In order to generate better and more detailed images for diagnostic purposes, the contrast agent helps highlight blood arteries, organs, or other structures.
