Background

Radiopaedia was started as a past-time project to store radiology notes and cases online by the Australian
neuroradiologist Neuroradiology is a subspecialty of radiology focusing on the diagnosis and characterization of abnormalities of the central and peripheral nervous system, spine, and head and neck using neuroimaging techniques. Medical issues utilizing neuroradio ...
Associate Professor Frank Gaillard in December 2005, while he was a radiology resident. He later became passionate in building the website and decided to release it on the web, advocating free dissemination of knowledge. The domain name for radiopaedia.org was registered on 11 January 2007. The Radiopaedia.org platform and text content are owned by Radiopaedia Australia

In 2010, almost all of the article and image collection from radswiki (a similar wiki-based radiology educational site) was donated to Radiopaedia. Its article content is currently limited to English.


Purpose

Radiopaedia’s mission is "to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all." Its intention is to benefit the radiology community and wider society and it relies on benevolent collaborations from radiologists and others with an interest in medical imaging. Similarly to

, registered users of the site are allowed to freely add and edit the majority of the content. This allows content to be progressively upgraded over years and for radiologists and society, in general, to continuously refine article content through time. The site also allows registered users to maintain their own personal case library of teaching cases. Rather than individually publishing articles, users are encouraged to integrate content with links to cases and journal articles and collaboratively refine content. In an attempt to reduce vandalism and to peer-review content, an editorial board moderates changes to ensure that the presented material is as accurate and relevant as possible. As with similar open edit sites, unreliability of content has been a concern; however, despite its open edit nature, it is ranked relatively high among user reviews. A survey done in 2020 shows that 90% of on-call radiology trainees in the United States are using Radiopedia and StatDx as the first and second line options to help them during their work. Educational benefit was also demonstrated when integrating Radiopedia-based training in medical curriculum.
