ESGAR

What ESGAR does

ESGAR (European Society of Gastrointestinal and Abdominal Radiology) is a Vienna-headquartered, Austria-registered not-for-profit professional and scientific association (ZVR 209922020) founded in 1990, which serves approximately 2,929 radiologists, residents and researchers (as of December 2025) with a primary interest in gastrointestinal and abdominal imaging across Europe and selected international markets. The society operates a multi-channel education platform: a flagship 38th Annual Meeting (rotating European city, Edinburgh scheduled for June 2027), a year-round calendar of on-site and online workshops (Liver Imaging, CT Colonography, Case Reading Week, MR Rectal Cancer, Masterclass in Small Bowel Imaging, etc.), a Junior ESGAR Summer School, an e-Academy webinar series, e-Tutorials, a Case of the Month program integrated with the EuroRad database, and a Research Fellowship and Mentorship pipeline. These programs are underwritten by an open-access journal (European Radiology Abdomen) launched jointly with the ESR and ESUR, by the EDGAR subspecialty diploma (administered via the European Board of Radiology), and by an ESGAR Guidelines programme that produces both monodisciplinary and multi-society recommendations (e.g., the July 2025 ECCO-ESGAR-ESP-IBUS IBD guideline).

The operating model is a non-profit subscription-and-event hybrid. Revenue is generated through membership dues at €75 (Junior) or €150 (Active and Corresponding) per member per year, paid event registrations (e.g., Case Reading Week at €1,990 for members / €2,490 for non-members), the €450 EDGAR examination and €75 diploma renewal fees, and corporate memberships with imaging-industry sponsors (Bayer, Bracco, GE HealthCare, Guerbet). Distribution is centralized through the Central ESGAR Office in Vienna (Brigitte Lindlbauer, Executive Director) supported by an Executive Board (President Prof. Jaap Stoker, President-Elect Prof. Giuseppe Brancatelli, Vice President Prof. Stuart Taylor) and committee chairs across Education, Diploma, Research and Workshops. Governance is by a General Assembly, with no equity ownership, no funding rounds, and no parent company; partnerships with the ESR, UEG, ESUR, ARGANZ and a deep network of European clinical societies (EASL, ECCO, ESGE, EPC, ESCP, ESDO, ESP, E-AHPBA, ESSO) anchor the society's reach into multidisciplinary guideline work.
