The European Society of Radiology (ESR) is an international medical society based in Vienna, Austria dedicated to the promotion and coordination of scientific, philanthropic, intellectual and professional activities of radiology in Europe. In addition to various other activities, the ESR serves as an umbrella organisation for European radiologists, organises the annual European Congress of Radiology (ECR) and coordinates the publication of European Radiology, a monthly peer-reviewed medical journal. Additionally, the ESR pilots the harmonisation of teaching programmes throughout Europe with various activities and initiatives. History Founded in 2005, the European Society of Radiology (ESR) was created through the merger of two established radiological societies; the European Association of Radiology (EAR), a federation of national radiological societies founded in 1962, and the European Congress of Radiology (ECR), the organising body of the eponymous congress which was first held in 1967<ref name="Thomas, The EAR">Thomas, A.

The EAR was tasked with coordinating a European congress and establishing a European counterpart to the Radiological Society of North America (RSNA), which had existed since 1915. By the time it was formally registered, the association comprised radiological member societies from nine countries - Belgium, France, Italy, Luxembourg, The Netherlands, Portugal, Spain, Switzerland, and West Germany. The European Congress of Radiology was to be held every four years in a different European city, starting in 1967 which Barcelona with took place in conjunction with the Radiological Federation of Latin Culture (Féderation Radiologique de Culture Latine). After successor congresses were held in Amsterdam (1971), Edinburgh (1975), Hamburg (1979), Bordeaux (1983) and Lisbon (1987), the EAR in 1985 founded a committee, chaired by Josef Lissner of the University of Munich, specifically tasked with organising future congresses. An ever-changing location and the lack of a consistent group of experienced radiologists responsible for the congresses were deemed obstacles to the most effective congress possible. As a result, the committee ultimately decided that the frequency of the congress should be increased to every two years and
