Society of Interventional Radiology

What Society of Interventional Radiology does

The Society of Interventional Radiology (SIR) is a nonprofit professional medical society founded in 1975 and headquartered in Fairfax, Virginia. It represents more than 8,000 practicing interventional radiology physicians, trainees, students, scientists, and clinical associates in the United States and internationally, providing them with education, training pathways, research funding, advocacy, clinical guidelines, publishing opportunities, and a community platform (SIR Connect). SIR is governed by a member-elected Board of Directors and operates with a small staff of 11-50 employees, with Eve Lee, MBA, CAE, serving as CEO since January 2025.

SIR's product and service portfolio is anchored by the VIRTEX Clinical Data Registry & Analytics Platform (launched 2025) for evidence-based quality improvement, the peer-reviewed Journal of Vascular and Interventional Radiology (JVIR) published in partnership with Elsevier (5,100+ monthly print subscribers; 41,300+ monthly website visits), the IR Quarterly member magazine (7,000+ print subscribers), the SIR Guidelines mobile app, and an annual Scientific Meeting plus specialized events such as SIR EDGE, Business of IR, and ACIR. Supporting infrastructure includes the SIR Foundation (a wholly owned research and education subsidiary), Clinical Specialty Councils, sections and committees, a Fellowship program, global outreach, and a Doctor Finder directory for patients. The technology stack includes Higher Logic/SIR Connect community software, Elsevier publishing infrastructure, and a member portal on sirweb.org.

SIR generates revenue across five primary streams: (1) recurring membership dues; (2) one-time registration fees for the Annual Scientific Meeting and educational events (e.g., ACIR $595, Business of IR $750, SIR EDGE $1,595); (3) advertising in JVIR, IR Quarterly, Guidewire newsletter (7,400+ subscribers, ~46.5% open rate), SIR Scan newsletter (10,000+ subscribers, ~46.7% open rate), and The Kinked Wire podcast (500+ downloads/episode); (4) tiered Vendor Directory listings (Gold $7,500, Silver $5,000, Bronze $2,500) reaching an 8,000+ IR-professional audience; and (5) the Corporate Ambassador Program with Vanguard, Leader, Advocate, and Associate tiers. As a 501(c) organization, SIR does not publicly disclose revenue, and its governance, advocacy through SIRPAC, and clinical guidelines function as a quasi-public-good utility for the IR specialty rather than a profit-maximizing enterprise.

Direct peers

• American College of Radiology (ACR): U.S. professional society for radiologists, including interventional radiologists. Directly comparable as a radiology specialty society offering membership, practice accreditation, guidelines, advocacy, and quality programs (e.g., ACR's imaging registries and accreditation services).
• Radiological Society of North America (RSNA): Largest radiology professional society globally, with a peer-reviewed journal (Radiology), major annual meeting, and education programs. Comparable peer because it competes for the same radiologist audience and offers analogous society products (journal, meeting, education, research funding).
• Cardiovascular and Interventional Radiology Society of Europe (CIRSE): European society dedicated to interventional radiology with annual meetings, journals, and member services. The closest international direct peer to SIR, addressing the same specialty with overlapping publications and educational offerings across an alternate geography.
• Society for Vascular Surgery (SVS): U.S. society for vascular surgeons, many of whom perform overlapping endovascular procedures with IRs. Comparable because it represents a parallel procedural specialty with its own journal, meeting, guidelines, PAC, and industry sponsorship relationships.
• Society of Nuclear Medicine and Molecular Imaging (SNMMI): U.S. imaging specialty society with peer-reviewed journal, guidelines, annual meeting, and industry partnerships. Comparable peer because it competes for the same radiology/imaging decision-maker audience, sponsors, and meeting calendar.

Emerging players

• Society of Interventional Oncology (SIO): Smaller subspecialty society focused on interventional oncology within IR. Comparable as a focused IR-adjacent society competing for a subset of the same members, sponsors, and meeting mindshare.

Broad incumbents

• American Heart Association (AHA): Large, broad cardiovascular health organization with member programs, journals (Circulation), advocacy, and industry partnerships that overlap with vascular and IR-related device manufacturers. Comparable as a much larger medical society operating in SIR's adjacent clinical and sponsor space.
• American College of Cardiology (ACC): Cardiology specialty society with guidelines, registries (e.g., NCDR), advocacy, and major industry sponsorships that overlap heavily with structural heart and vascular IR procedures. Comparable as a larger specialty society that competes for industry sponsorship dollars across cardiovascular IR.
• American Medical Association (AMA): Largest U.S. physician association with advocacy, CPT coding ownership, and broad medical society infrastructure. Comparable as an umbrella society whose advocacy, coding resources, and publications partially substitute for what SIR offers its narrower specialty audience.

Regional players

• Asia Pacific Society of Cardiovascular and Interventional Radiology (APSCVIR): Regional IR society covering Asia-Pacific. Comparable as an IR-focused society operating in a different geography, providing a benchmark on how SIR's programming and sponsorship model translate internationally.
