ESOI - European Society of Oncologic Imaging

What ESOI - European Society of Oncologic Imaging does

ESOI (European Society of Oncologic Imaging) is an apolitical non-profit professional medical society registered in Vienna, Austria (ZVR 897953653), operating under the institutional umbrella of the European Society of Radiology (ESR). Founded in 2011 and active since at least 2015, ESOI serves radiologists, radiology residents, and allied sciences professionals focused on cancer imaging, with active members distributed across five continents (84% Europe, 7% Asia, 3% Africa, 2% North America). The society's core mission is to establish oncologic imaging as a recognized subspecialty and to deliver high-quality multidisciplinary education by connecting radiologists with surgical oncologists, medical oncologists, radiation oncologists, and basic scientists.

ESOI's product portfolio is built around educational programs rather than software. Core offerings include the annual ESOI Touchdown congress (scheduled for October 29-31, 2026 at DKFZ Heidelberg), the ESOI-EORTC Workshop series on RECIST 1.1 tumor response assessment, a monthly CME-accredited webinar program (1 ECMEC per session, 100+ archived lectures), ESOR fellowship and scholarship exchange programs, and a structured reporting template for pancreatic cancer staging co-developed with Smart Reporting. Distribution is event-driven and community-led: members are acquired through society partnerships, reduced event pricing, and access to the on-demand content library.

The business model rests on four revenue streams: recurring annual membership fees (€50 for full/allied members, €25 for residents, custom for corporate), event registration fees (€210-€695 per attendee), webinar CME accreditation monetization, and corporate sponsorships (notably Bracco as Exclusive Webinar Sponsor 2026 and Siemens Healthineers as a visible corporate partner). The society is lean (5 employees) and relies on an Executive Committee and four standing committees (Education, Membership, Research, Young Radiologists) for governance and content production. ESOI maintains MoU-based strategic alliances with five major oncology societies (EACR, ESSO, ESTRO, ECO, ESDO, SOII) and technology/institutional partners including Smart Reporting, EORTC, DKFZ, Mint Medical, and ESR.

Direct peers

• European Organisation for Research and Treatment of Cancer (EORTC): EORTC is ESOI's direct joint-workshop partner for the RECIST qualification programme. Comparable non-profit, membership-oriented cancer research organisation hosting imaging-relevant education and clinical-trial methodology training.
• European SocieTy for Radiotherapy & Oncology (ESTRO): ESTRO is an ESOI partner with a parallel European society model: membership tiers, annual congress, schools, and multidisciplinary cancer imaging/radiotherapy education. Highly comparable structure and overlapping audience.
• European Society of Surgical Oncology (ESSO): ESSO is an ESOI MoU partner with a parallel European society model: membership tiers, congresses, education, and multidisciplinary cancer management focus. Strong structural and audience overlap with ESOI.
• European Society of Radiology (ESR): ESR is ESOI's umbrella organization and the largest European radiology society. Comparable in operating model (membership, congresses, education, journals) but operates at a much broader specialty scope rather than oncologic imaging alone.
• American College of Radiology (ACR): ACR is a US-based radiology professional society providing membership, education, practice standards, and accreditation — directly comparable to ESOI in mission and operating model, though primarily US-focused and broader in scope.
• Society of Nuclear Medicine and Molecular Imaging (SNMMI): SNMMI is a US-based imaging society offering membership, annual meetings, journals, and continuing education. Comparable operating model to ESOI, with overlap in oncologic imaging content (PET/CT, PET/MRI) and CME delivery.
• Radiological Society of North America (RSNA): RSNA is the world's largest radiology professional society, offering membership, annual congress, CME, journals, and educational resources. Highly comparable operating model to ESOI, but with a North American base and broader (non-oncologic) radiology focus.
• International Cancer Imaging Society (ICIS): ICIS is the closest functional peer: an international society dedicated to oncologic imaging education, running annual meetings, workshops, and CME-accredited content for radiologists. It mirrors ESOI's subspecialty focus and member-driven delivery model.

Broad incumbents

• European Society for Medical Oncology (ESMO): ESMO is the leading European medical oncology society, operating a similar membership-and-congress model. Overlaps with ESOI on multidisciplinary cancer education but covers the full medical oncology specialty, not just imaging.
• American Society of Clinical Oncology (ASCO): ASCO is the largest global clinical oncology society with membership, congresses, journals, and CME. Highly comparable member-and-education operating model, with imaging featured as a cross-cutting topic rather than as the core focus.
