Case-based training is a staple of radiology education. We recently developed an approach to case-based training that uses a database structure for building interesting case files rapidly and allowing for files to be used and reused in a variety of formats. Our system utilizes two database structures, one housing traditional book elements (text-based case histories, descriptions, key images, and multiple choice questions) and one housing radiology exam elements (dcm4chee, an open source PACS). The complete case-based teaching system makes use of FileMaker (FileMaker Inc., Santa Clara, California) for designing front-end user interfaces and ResolutionMD (Calgary Scientific, Calgary, Canada) for allowing users to interact with the full radiological exam. Both platforms can be used via the web on a computer or through 3rd party apps on iOS devices.

We evaluated the utility and design of our iPad learning platform with three staff radiologists and three fellows using 39 cases of Crohn’s disease. We evaluated the new platform in comparison to an existing learning system that uses a paper format for book elements and ClearCanvas (ClearCanvas, Toronto, Ontario) on a dedicated laptop for image exams. We found enthusiasm for an electronic learning format; however several criticisms were offered related to the layout and ‘buttonology’ of our iPad tool, and users expressed a desire for a web-based option.

Based on feedback from the initial evaluation, we refined the interface and adjusted several aspects of content delivery. Importantly, the database structure allows modifications to the learning tool template to be made quickly and content redeployed without significant input or effort from the provider of the interesting case.

We have developed a new system based on two databases allowing rapid deployment of interesting cases in polished and interactive teaching and learning tools. Our initial evaluation provided us with an opportunity to exploit this layered (interface on top of database) method for content delivery and make changes to the interface without adjustment to the core content or its storage format.
