100 countries and more than 4,000 scientific papers and exhibits, the ECR has developed into the largest radiological meeting in Europe since it was first held in its ‘new’ format in September 1991. It is held annually at the end of February or early March. Congress attendees include radiology professionals, professionals of allied sciences, industry representatives, and press reporters for both the medical and consumer press. The ECR hosts an accompanying industrial exhibition which provides a chance for congress-goers to explore state-of-the-art medical imaging technology and related services. International Day of Radiology The International Day of Radiology is an annual event held with the aim of building greater awareness of the value that radiology contributes to safe patient care and improving understanding of the role radiologists and radiological technologists play in healthcare. It was launched in 2012 and is a joint initiative of the European Society of Radiology (ESR), the Radiological Society of North America (RSNA) and the American College of Radiology (ACR). November 8, the day that Wilhelm Conrad Röntgen discovered the existence of x-rays in 1895, was chosen as a day of action and awareness. The theme of Sports Imaging (a sub-specialty of musculoskeletal radiology) has been selected for the 2019 International Day of Radiology. Previous themes include Cardiac Imaging (2018), Emergency Radiology (2017) and Breast Imaging (2016). In further celebration of the day, the ESR annually publishes a book containing curated scholarly research on the theme of that particular year. European Institute for Biomedical Imaging Research The European Institute for Biomedical Imaging Research (EIBIR), established in 2006 on the initiative of the European Society of Radiology (ESR), aims to improve cooperation between research institutes, academic departments and industry that form the European biomedical imaging community with the goal of improving the diagnosis, treatment and prevention of diseases. It actively supports research networking activities and common initiatives and interoperability in the field of biomedical imaging research. European and International Affairs The European Society of Radiology (ESR) undertakes various international and EU-level initiatives designed to support member interests internationally and in government. One of these initiatives is the ESR’s collaborative work on cancer. Various cancer initiatives have been undertaken including collaboration with the European Joint Action on Cancer Control (CanCon JA). The ESR is part of the European Commission Initiative on Breast Cancer (ECIBC) whose aim is to develop new European Breast Guidelines, evidence-based recommendations for breast cancer screening
