The Radiological Society of North America (RSNA) is an international society of radiologists, medical physicists and other medical professionals with more than 54,000 members across the globe. Based in Oak Brook, Illinois, RSNA was established in 1915. RSNA hosts one of the world’s largest annual medical meetings,[1] a week-long event which starts the last Sunday of November in Chicago. The society also publishes two peer-reviewed journals: Radiology, offering radiology research and reviews, and RadioGraphics, dedicated to continuing education in radiology. The Society also develops and offers informatics-based software solutions in support of a universal electronic health record, sponsors research to advance quantitative imaging biomarkers, and conducts outreach to enhance education in developing nations. Through its Research & Education Foundation, RSNA provides millions of dollars in funding to investigators. The presidency of the RSNA is held as a one-year term. The current president is Mary C.
