From online textbooks to educational social media posts, digital learning tools are transforming medical education. Spaced repetition programs are a popular tool, with 70% of first-year medical students reporting using the free, open-source flashcard application Anki.1 The Anki program pairs active recall and spaced repetition learning principles with a simple but versatile user interface.2 Spaced repetition flashcard programs such as Anki are uniquely suited to radiology education because they strengthen image-based recall, a necessary skill for radiology trainees to develop. In this review, we will describe the science behind active recall and spaced repetition programs, introduce the Anki platform, and describe future directions for its potential as an educational resource for radiology.
