About us

ESREuropean Society of Radiology

Founded in 2005, by merging the European Congress of Radiology (ECR) and the European Association of Radiology (EAR), the European Society of Radiology (ESR) is an apolitical, non-profit organisation dedicated to strengthening and unifying European radiology. With more than 73,000 members across the globe, it has grown to become the largest radiological society in the world and hosts one of the biggest and most innova­tive scientific meetings in Europe, the European Congress of Radiology, in Vienna each year (more than 25,000 participants at ECR 2017). The Society works closely with national radiological societies across Europe and further afield, while establishing relationships with major international organisations from other related fields. It also monitors developments on the EU level which could have an impact on research and practice in radiology, with the best interests of the patient as its overriding goal.

The Society publishes the journals European Radiology, Insights into Imaging and European Radiology Experimental.

The mission of the European Society of Radiology is to serve the healthcare needs of the general public by supporting scientific research, education and training while constantly striving to improve the quality of radiological practice.

Radiological Society of North America

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, 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 (R&E) Foundation, RSNA provides millions of dollars in funding to investigators.

American College of Radiology

The American College of Radiology (ACR), founded in 1923, is a non-profit professional medical association composed of diagnostic radiologists, radiation oncologists, interventional radiologists, nuclear medicine physicians, and medical physicists. It is based in Reston, Virginia, with offices in Philadelphia, and Washington, D.C. The college publishes The Journal of the American College of Radiology (JACR) and The ACR Bulletin.
