Contrast media enhance and boost image quality (or pictures), so that the radiologist (a medical doctor qualified to analyze the pictures and give a written report to the patient's physician or medical) may report more reliably on how the body functions and whether there is any illness or abnormality present. Contrast Media Contrast media, also called contrast agents, are used for blood enhancement and tissue perfusion. This includes computed tomography (CT) based contrast based on iodine, MRI based agents based on gadolinium, and ultrasound contrast agents used in the lipid bubble. The two primary types of contrast media dependent on iodine are ionic and nonionic. The development of ionic contrast media-enabled radiologists has helped to visualize vessels and organs on various imaging studies. Some have a degree of toxicity, however, and the advent of non-ionic media resulted in less adverse reactions. New contrast media are low ionic, iso-osmolar, and gadolinium-bas...
