Controversies in Drug Allergy: Radiographic Contrast Media.

The risk for developing immediate or delayed hypersensitivity reactions to radiocontrast media (RCM) interferes with the diagnosis and treatment of a number of patients requiring imaging diagnostic methods for many common diseases. A group of experts met in Orlando, Florida, in March 2018 to analyze the similarities and differences in the management of RCM reactions in different areas of the world. This paper presents a summary of the recommendations provided by this consensus group, highlighting controversial issues and unmet needs that require further research.
