Spaced Repetition Learning: Exploring Its Potential and Practical Application in Radiology Education

In today's medical landscape, rapidly learning vast amounts of information requires innovative learning methods. Spaced repetition tools (like Anki) aid efficient knowledge absorption and retention among medical trainees. Yet, adoption of these tools in radiology medical student education lags despite proven effectiveness. This article highlights spaced repetition as a learning tool alongside other evidence-based educational practices, aiming to revolutionize radiology education among medical students. We (1) describe the educational theory and current application of spaced repetition in the setting of other learning techniques often found in undergraduate medical education; (2) underscore the underutilization of tools such as Anki in radiology education; and (3) offer practical guidance for educators interested in integrating spaced repetition into their teaching methodologies.

Perspectives of brain imaging with PET systems

In this partial review and partial attempt at vision of what may be the future of dedicated brain PET scanners, the key implementations of the PET technique, we postulate that we are still on a development path and there is still a lot to be done in order to develop optimal brain imagers. Optimized for particular imaging tasks and protocols, and also mobile, that can be used outside the PET center, in addition to the expected improvements in sensitivity and resolution. For this multi-application concept to be more practical, flexible, adaptable designs are preferred. This task is greatly facilitated by the improved TOF performance that allows for more open, adjustable, limited angular coverage geometries without creating image artifacts. As achieving uniform very high resolution in the whole body is not practical due to technological limits and high costs, hybrid systems using a moderate-resolution total body scanner (such as J-PET) combined with a very high performing brain imager could be a very attractive approach. As well, as using magnification inserts in the total body or long-axial length imagers to visualize selected targets with higher resolution. In addition, multigamma imagers combining PET with Compton imaging should be developed to enable multitracer imaging.
