WebIodinated contrast media (CM) are administered to millions of patients every year, yet controversy continues to exist regarding the safety of the various agents. Iodinated CM are either ionic or non-ionic, and vary in their osmolality relative to plasma. It is generally accepted that first-generation ionic, high-osmolality CM (HOCM) are less ... WebSerious or fatal reactions have been associated with the administration of iodine-containing radiopaque media. Serious, rarely fatal, thromboembolic events causing myocardial infarction and stroke have been reported during angiographic procedures with both ionic and nonionic contrast media.
