General overview of

Last revised by Frank Gaillard on 6 Feb 2023 is a rapidly growing peer-reviewed open-edit radiology resource primarily compiled by radiologists and radiology residents/registrars and fellows from across the globe. The site aims to create the best radiology reference available, and to make it available for free, forever and for all.

It is designed to facilitate meaningful collaboration between all our contributing users, as well as allow non-contributors to browse through thousands of articles and interesting and illustrative cases. Read more about contributing to Radiopaedia.

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 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. is built from two major components: 

  1. articles: collaborative efforts to provide a single atomic page on any and all topics relevant to the practice of radiology

  2. cases: pages that present a case to the community - these belong to the contributing user although they can be viewed by the community and added to articles, tutorials or quizzes

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

An integral part of is that it is collaborative. 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 may be 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 cases on 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 (and site administrators) can edit them.

For a project like this to work, we must all be on the same page: we need to understand where we are going, understand the boundaries of the project and most of all respect and support each other:
