Used primarily as a radiocontrast agent in medical imaging procedures. It is administered intravenously or orally to enhance the visibility of blood vessels, organs, and other internal structures during X-ray examinations, including angiography, urography, and computed tomography (CT) scans. Its high iodine content effectively absorbs X-rays, providing clear contrast between tissues and improving diagnostic accuracy. Due to its water solubility and rapid renal excretion, it is suitable for visualizing the urinary tract and cardiovascular system. Commonly formulated in combination with meglumine to reduce osmolality and improve patient tolerance.
