Used as a contrast agent in diagnostic imaging procedures such as computed tomography (CT) scans, angiography, and urography. Enhances the visibility of blood vessels, organs, and tissues by increasing the contrast in X-ray images. Particularly effective in visualizing the brain, heart, aorta, and kidney due to its high solubility and low osmolality. Administered intravenously, it helps detect tumors, vascular diseases, and structural abnormalities. Its non-ionic nature reduces the risk of adverse reactions, making it suitable for patients with cardiovascular or renal conditions.
