Severe allergic-like contrast reactions: epidemiology and appropriate treatment.

Epinephrine is the most important treatment for severe allergic-like contrast reactions. The signs and symptoms of a severe reaction and the dose and methods of epinephrine administration are important for all radiologists to master. In this review article, we review the epidemiology of severe allergic-like contrast reactions, their common clinical manifestations, and their appropriate treatment, with a focus on correct epinephrine administration. We also discuss systematic limitations in the training of current and future radiologists, and recommend strategies for improvement.
