The International Society of Radiology

What The International Society of Radiology does

The International Society of Radiology (ISR) is a private, non-profit professional federation founded in 1925 at the first international radiology congress in London and formally incorporated in 1953. It is the only international federation of national radiological societies, comprising 35+ national member societies and six continental members representing every inhabited continent. ISR holds Non-State Actor official relations status with the World Health Organization — the only radiology organization with this designation — and maintains Practical Arrangements with the International Atomic Energy Agency through 2027.

ISR's product portfolio is programmatic rather than software-based. Core offerings include the biennial International Congress of Radiology (ICR), with ICR 2026 scheduled as a joint meeting with the 49th Colombian Congress of Radiology in Cartagena; the ISR Quality and Safety Alliance (ISRQSA), which convenes all major global radiation protection campaigns; the Béclère-Fuchs Foundation established in February 2025 as the charitable arm funding LMIC imaging access; free Radiation Protection Training Programs co-developed with Image Gently and the IAEA; the monthly Illuminations newsletter; curated open-access journal articles; and the annual International Day of Radiology on November 8. The organization is not a technology company in the conventional sense — its proprietary assets are institutional convening power, regulatory access, and content curation.

ISR generates revenue through four streams: membership dues set at $0.75 USD per individual society member annually across member societies; corporate sponsorships to the Béclère-Fuchs Foundation structured at Platinum ($50,000), Gold ($25,000), Silver ($10,000), and Bronze ($5,000) tiers; individual donations at Platinum ($5,000) through Bronze ($500) tiers; and revenue from the ICR congress. Operations are run from a headquarters in Reston, Virginia (hosted within the American College of Radiology infrastructure) and a European Liaison Office in Vienna hosted by the European Society of Radiology. The organization is led by President Bibb Allen Jr., MD, with Boris Brkljačić as President-elect following the November 2024 passing of President-Elect Sudhir Vinayak, and is celebrating its centennial in 2025-2026.

Expansion highlights5 records

Direct peers

• International Society of Radiographers and Radiological Technologists: Global allied-health society that collaborates with ISR on patient shielding webinars, World Patient Safety Day, and radiation safety culture. Direct peer in mission and international federation model, focused on radiographers rather than radiologists.
• International Commission on Radiological Protection: International body that sets the global radiation protection standards which ISRQSA operationalizes. Spun out of the same 1928 Stockholm Congress that founded the ISR lineage and is a direct collaborating partner through ISRQSA on radiation safety initiatives.
• Asian Oceanian Society of Radiology: Continental society covering Asia and Oceania, one of ISR's six continental members. Direct peer in its role as a regional federation of national radiology societies with overlapping radiation safety and education programs (AsiaSafe).
• European Society of Radiology: Continental federation of European national radiology societies that hosts ISR's European Liaison Office in Vienna. Direct peer as a federation of national societies with overlapping leadership, congress activity (ECR parallels ICR), and ESR is one of ISR's six continental member societies.
• International Organization for Medical Physics: Global federation of medical physics organizations collaborating with ISR through ISRQSA on radiation safety culture. Direct peer as a federation of national societies in a radiation-medicine discipline adjacent to radiology.
• World Federation of Pediatric Imaging: Pediatric radiology organization with formal collaboration agreement with ISR, co-hosted WHO-ISR-WFPI World TB Day 2022 symposium. Direct peer on pediatric radiation protection (Image Gently alliance) with overlapping leadership.

Broad incumbents

• American College of Radiology: US professional society of radiologists that hosts ISR's US headquarters operations in Reston, VA. Functions both as a direct peer (national society ISR federates) and as a broad incumbent with far deeper staff resources and policy influence within US healthcare.
• Radiological Society of North America: Much larger radiology society operating the flagship RSNA annual meeting and Radiology journal. Comparable mission (advancing radiology practice/education) but anchored in North America and substantially larger in budget, staff, and membership scale.
• American Roentgen Ray Society: One of the oldest US radiology societies (founded 1900), publisher of the AJR journal. Comparable peer on the scholarly publishing and continuing education axes, but with a regional rather than international federation scope.

Regional players

• Royal College of Radiologists: UK national radiology college and a member society of ISR. Comparable peer because it operates a fellowship/training/education function and represents UK radiologists internationally, but its geographic scope is the UK rather than global federation.
