What is

Radiopaedia is a rapidly growing open-edit educational radiology resource which has been primarily compiled by radiologists and radiology trainees from across the world. Our mission is to create the best radiology reference, and to make it available for free, forever.

Your first edit

You can update (and write) articles on Radiopaedia If you see a typo or missing link to an existing article, it's easy to make an edit as soon as you see it.

Content types

Radiopaedia comprises two fundamental content types (articles and cases) and playlists (ordered collections of cases).


Articles are collaborative efforts to provide a single canonical page on any and all topics relevant to the practice of radiology. Every edit counts, so don't hesitate to jump in and share what you know.


Exceptional cases and up-to-date articles are vital for Radiopaedia. Please consider helping by uploading your cases. There is no better way to show your appreciation for the site than by making it even more informative.


Create and share playlists to help advance medical information around the globe. Curate focused playlists on specific topics for presentations to help other medical professionals teach radiology, or formulate quiz playlists to support medical students in their education.

Editorial standards

The accuracy of Radiopaedia. content is overseen by a dedicated group of volunteer editors who 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. 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.
