Iopamidol is widely used as a contrast agent in medical imaging procedures, particularly in X-ray and CT scans. It helps enhance the visibility of blood vessels, tissues, and organs by providing clear differentiation between structures. This is especially useful in diagnosing conditions such as blockages, tumors, or abnormalities in the cardiovascular, urinary, and central nervous systems. Its low viscosity and high solubility make it suitable for intravenous or intrathecal administration, ensuring effective imaging with minimal patient discomfort. Additionally, iopamidol is often preferred due to its lower risk of adverse reactions compared to older contrast agents.
