Used as a contrast agent in diagnostic imaging procedures, particularly in angiography and urography, to visualize blood vessels and the urinary tract. Its high iodine content enhances X-ray imaging by improving the contrast between tissues. Commonly administered via injection, it helps detect abnormalities such as tumors, blockages, or vascular malformations. Due to its water solubility and relatively rapid excretion through the kidneys, it is effective for short-term imaging with minimal retention in the body.
