Contrast media agents have been used to increase picture quality in MRI exams for decades, and some of the agents have a great overall safety record. A search was conducted in electronic sources, such as PubMed and Embase, for publications published up to the start of 2022 that discussed contrast media agents used in radiograph situations. The majority of adverse reactions to contrast media are regarded to be idiosyncratic or pseudoallergic in nature. They are unexpected and not dose-dependent, and they may entail the release of histamine as well as other biological mediators such serotonin, prostaglandins, bradykinin, leukotrienes, adenosine, and endothelin. Because antibodies to contrast media could not be reliably shown, there is no definitive proof that these adverse reactions to contrast media are allergic.
