A Narrative Review on the Power of Contrast Media in Radiology: Clinical Indications, Associated Risks, and Strategies for Safe Management
Main Article Content
Abstract
Abstract
Contrast media have become indispensable in modern radiology, significantly enhancing the ability to visualize internal structures and diagnose a variety of medical conditions. These agents are essential in imaging techniques such as CT, MRI, and X-ray, providing clearer, more detailed images of organs, tissues, and blood vessels. However, the use of contrast media is not without risks, including allergic reactions, nephrotoxicity, and gadolinium retention, particularly in patients with pre-existing conditions such as kidney disease. This narrative review explores the clinical applications, potential risks, and management strategies associated with contrast media. Additionally, it highlights emerging advancements, such as non-iodinated and biodegradable agents, and the integration of artificial intelligence and molecular imaging, which promise to enhance safety and diagnostic accuracy. As the field continues to evolve, contrast media will remain central to diagnostic imaging, but ongoing research and technological advancements are necessary to address their risks while improving patient outcomes.
Keywords: Contrast media, radiology, CT, MRI, X-ray, nephrotoxicity, gadolinium retention, allergic reactions, non-iodinated agents, biodegradable agents, molecular imaging, artificial intelligence, diagnostic imaging.
