Iodinated compounds are chemical substances that contain iodine atoms in their molecular structure. They are commonly used in medical imaging, particularly in X-ray and CT scans, as contrast agents to enhance the visibility of internal organs and blood vessels. These compounds help doctors diagnose various conditions by providing clearer images. In addition to medical applications, iodinated compounds are also used in pharmaceuticals and disinfectants. They can have antimicrobial properties, making them effective in preventing infections. However, some individuals may have allergies or sensitivities to iodine, which can limit the use of these compounds in certain situations.
