Content types

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

The accuracy of Radiopaedia.org 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.
