Foundation
The European Society of Radiology (ESR) was founded in February 2005 by merging the European Congress of Radiology (ECR) and the European Association of Radiology (EAR), thus establishing a single house of radiology in Europe.

Organisation
The European Society of Radiology is an apolitical, non-profit organisation, dedicated to promoting and coordinating the scientific, philanthropic, intellectual and professional activities of Radiology in all European countries. The Society's mission at all times is to serve the health care needs of the general public through the support of science, teaching and research and the quality of service in the field of Radiology.

Idea
The idea was taken in order to strengthen and unify European radiology and to ensure competitiveness compared to other radiological events and institutions. Furthermore, the ESR will safeguard the general interests of European radiology.
