Adverse Effects of Iodine-derived Intravenous Radiopaque Contrast Media

Radiol Technol. Jul-Aug 2015;86(6):623-38; quiz 639-42.


Although the advent of nonionic low-osmolar contrast agents has reduced the probability of a reaction to radiopaque contrast media derived from tri-iodinated benzoic acid, reactions still occur. Radiologic technologists must understand and know how to manage adverse effects of contrast media. Prompt attention to patients who exhibit the early signs of an adverse reaction can help to ensure the reaction does not progress to become severe or life-threatening.
