The radiology teaching file teaching cases in a RadPix system can be used with the built-in audience participation system, which has been successfully used at the 2017, 2018 and 2019 RSNA Annual Meetings. This cloud-based system can support hundreds of users at a time scrolling through a series of images and answering questions. The presenter can show how many participants have answered questions and then display the distribution of the participants’ answers.
