This introduction chapter is written by Prof. Michael Fuchsjäger, Chair of the European Society of Radiology (ESR)’s Value-Based Radiology Subcommittee, Prof. Lorenzo Derchi, Chair of the ESR Board of Directors, and Dr. Adrian Brady, Chair of the ESR Quality, Safety and Standards Committee. Prof. Derchi and Dr. Brady are also ex officio members of the Value-Based Radiology Subcommittee. The Value-Based Radiology Subcommittee was established with the aim of supporting radiologists in fulfilling their central role in healthcare while assisting them in the development of “appropriate metrics, which capture their true contribution and added value to patient care” (European Society of Radiology (ESR), https://www.myesr.org/about/organisation/executive-council#paragraph_grid_16643, Accessed 28 May 2019, 2019). The Subcommittee takes an active role in promoting value-based radiology to patients, through patient groups, and to healthcare professionals, through various publications and other activities, including dedicated sessions and lectures at the European Congress of Radiology (ECR) and stakeholder events such as the ECCO (European CanCer Organisation) summit 2018 and COCIR (European Coordination Committee of the Radiological, Electromedical and Healthcare IT Industry) General Assembly 2018. Furthermore, the Subcommittee collaborates with other radiological societies around the world on various initiatives.
