Radiopaedia.org is an open-source radiology education resource - this means that it is written by volunteer contributors from all around the world.
Often it appears a daunting step to go from reader to contributor, but getting involved is very easy and there is a friendly editorial board, who can help guide you through the process.
Just hit the edit button
See a spelling mistake that needs fixing or want to add a practical point? Just hit the edit button and make the necessary changes! Edits don't have to be large and even the smallest edit helps.
If you've had a little taste and want to contribute something more substantial, then have a look through the style guide and standard article structure and get stuck in revising an existing article or start an entirely new one.
Radiopaedia.org's editors always have projects on the go and are more than willing to help out any contributor. Just contact one of the editors, shoot through an email to the editorial group or you can contact Henry Knipe, managing editor for content development.
