App Review Series: CTisus iPearls.

Thousands of "pearls" or facts related to radiology or imaging are accessible through a categorically organized user interface. Pearls are divided up into anatomical regions, as well as non-organ-specific categories. Information is easily accessible with an ad-free interface matched with full offline capability. User interface leaves much to be desired as it appears dated and difficult to navigate at first. Pearls are not easily searchable within the application and unexperienced users may find it difficult to quickly answer targeted questions using this application alone. This application compiles pearls of wisdom pulled from thousands of peer-reviewed publications and organizes them in an easy to use format. While this is designed with the well-informed user in mind, it can serve as an excellent resource for users of all levels of experience seeking bite-sized pieces of imaging-related information.
