Radiopaedia is a non-profit-making wiki-based international collaborative radiology educational web resource containing reference articles, radiology images, and patient cases.[1] It also contains a radiology encyclopedia. It is currently one of the largest freely available radiology related resources in the world with more than 16000 patient cases and over 7000 collaborative articles on radiology-related topics which are of varying quality. In 2012, it became part of the UBM medica network.


The site was initially programmed using MediaWiki, the same program platform as Wikipedia, but now runs on a bespoke code written by TrikeApps. In 2010, almost all of the article and image collection from radswiki (a similar wiki-based radiology educational site) was donated to Radiopaedia.


The aim of according to its founder is "to develop an online text and case database where information is up to date and relevant to the needs of both registrar/resident and consultant radiology staff."[2] 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 radiology.

It was founded by the Australian neuroradiologist Dr. Frank Gaillard in December 2005.[3] It was initially Australian-led but now has a worldwide collaboration. Its article content is currently limited to English.

Similarly to Wikipedia, 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 peer-review content, a panel of section editors are appointed time to time to review changes and 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 highly among user reviews.[4] [5]

Sub sites[edit]

Radiopaedia also maintains several other educational subsites which include radiology signs - a tumblr feed with selected signs radiology channel - a YouTube channel containing educational videos
