Used as a contrast agent in medical imaging procedures such as CT scans, angiography, and myelography to enhance the visibility of blood vessels, organs, and tissues. Its low osmolality and high water solubility make it safer and better tolerated compared to older contrast agents. Commonly administered intravenously, intrathecally, or intra-arterially depending on the diagnostic need. Widely preferred for its minimal risk of adverse reactions and effective imaging performance.
