Use of an Online Education Platform to Enhance Patients' Knowledge About Radiation in Diagnostic Imaging.

Purpose: The aim of this study was to compare the impact of a digital interactive education platform and standard paper-based education on patients' knowledge regarding ionizing radiation.

Methods: Beginning in January 2015, patients at a tertiary cancer center scheduled for diagnostic imaging procedures were randomized to receive information about ionizing radiation delivered through a web-based interactive education platform (interactive education group), the same information in document format (document education group), or no specialized education (control group). Patients who completed at least some education and control group patients were invited to complete a knowledge assessment; interactive education patients were invited to provide feedback about satisfaction with their experience.
