CONTRAST AGENTS IN RADIOLOGY: TYPES, RISKS AND PRECAUTIONS

Аннотация

Abstract Contrast agents are essential pharmaceutical compounds used in medical imaging to enhance the visualization of anatomical structures and pathological processes. This review examines the various types of contrast agents employed in radiology, their associated risks, and the necessary precautions to ensure patient safety. Understanding the proper selection, administration, and monitoring of contrast agents is crucial for optimizing diagnostic accuracy while minimizing adverse effects. This article provides a comprehensive overview of iodinated contrast media, gadolinium- based agents, barium compounds, and newer contrast materials, along with evidence- based guidelines for their safe clinical application.
