About Radiopaedia.org

Radiopaedia.org is a rapidly growing, open-edit radiology resource, compiled by radiologists and other health professionals from across the globe.

Our mission is to create the best possible radiology reference and teaching site and make it available to everyone, for ever, for free.

All we need to accomplish this is for you to share some of your expertise and a few of your precious moments. By pooling our collective knowledge and experience, we can make a real difference in how people all over the world are imaged and diagnosed. Every new article, every case, and every correction counts.

While the primary aim of Radiopaedia.org is to allow the creation of an up-to-date resource for the radiology community, it is also about creating a community. It is focused on bringing together like-minded individuals who can collaborate on Radiopaedia.org content as well as on other projects.

Working together to create content

Articles are collaborative efforts to provide a single canonical page on any and all topics relevant to the practice of radiology. As such, articles are written and edited by a great many users over a period of time. Although this can be intimidating at first, the end result is something far more valuable than what can be achieved purely through individual effort. So, if collaboration is not your thing, writing articles is not for you. We like properly referenced content with subscription-free (open access) references, allowing readers and editors to cross-check the validity of articles and their content.

Sharing your interesting cases with the world

Each case page presents a single case to the community. While these cases belong to the contributing user, they can be viewed by the community and added to articles, tutorials, or quizzes. Sharing cases on Radiopaedia.org is different to writing articles. You can upload your interesting cases. You or others can then link them to existing articles. Moreover, you can add descriptions of the case and the imaging safe in the knowledge that only you (as well as editors and site administrators) can edit them.

Contributing Content

Exceptional cases and up-to-date articles are vital for Radiopaedia.org. To take the first steps towards contributing content, see the quick “how to” videos on our style guide and help page.


The accuracy and continued development of Radiopaedia.org is overseen by a dedicated group of volunteer editors. The open credentials and desire to create a free world-class resource are similar to those of Wikipedia. However, the importance of accurate information means that checks and balances of additions are required for Radiopaedia.org and our editors provide this. They constantly review additions and changes to articles and cases, something that is facilitated by being spread around the globe through a variety of time zones.

Expert Advisers

Our editors also draw upon the knowledge of our expert advisers. Our expert advisers are known to not only be experts in their field and educators, but to also support the radiology free open access medical education movement (#FOAMrad).
