What Radiopaedia does

Radiopaedia is an online collaborative radiology education platform founded in 2005 and operated by Radiopedia Events Pty Ltd, headquartered in Melbourne, Australia. The web-based platform combines a peer-reviewed wiki of radiology articles and cases (organized by anatomy, body system, and pathology) with a commercial education catalog covering 500+ hours of content, including 33+ structured courses, a 300+ lecture library, 400+ case reads, 15+ case workshops, 28 anatomy modules, and an exam practice question bank of 1,600+ items. The platform is ACCME-accredited and awards up to 455 AMA PRA Category 1 Credits to physician learners, and it hosts an annual virtual conference (2026 edition scheduled July 16-21).

The business model layers four revenue streams: (1) the All-Access Pass subscription priced 12 or 24 months across four country-income tiers (Tier 1 consultant up to $1,225 for 2 years, down to concession passes for trainees) with ad-free browsing and CME credits included; (2) individual course purchases (e.g., $20 per course, 12-month access); (3) third-party advertising and a Gold Supporter program that removes ads; and (4) a Free Access Program covering 125 low- and middle-income countries via Research4Life eligibility. Distribution is direct-to-consumer through radiopaedia.org with self-serve checkout, supplemented by a nascent group/institutional sales channel for 5+ users. The customer base spans practicing radiologists, radiology trainees, medical students, non-radiologist physicians, and allied health professionals (nurses, radiographers, physiotherapists) across at least 10 paid geographies including the US, UK, Germany, France, Australia, Canada, India, China, Japan, and Brazil.

Operationally, Radiopaedia runs with a small team of 11-50 employees, leveraging its volunteer global contributor community for content creation and peer review rather than a fully in-house editorial staff. The legal entity is a private Australian company with no disclosed funding rounds, parent company, subsidiaries, patents, or M&A history, indicating a bootstrapped operating model. The 20-year continuous operation (copyright 2005-2026) and absence of any leadership, restructuring, or regulatory adverse events point to a stable, self-sustaining organization.
