Used primarily as a contrast agent in medical imaging, particularly in X-ray and CT scans. It enhances the visibility of blood vessels, organs, and other internal structures, aiding in accurate diagnosis of conditions like tumors, blockages, or abnormalities. Its high iodine content makes it effective for absorbing X-rays, providing clear images. It is administered intravenously or orally, depending on the area being examined. Known for its low toxicity and rapid excretion, it is widely used in radiology for both adults and children.
