The multi-user immersive virtual environment Second Life® has been used to teach radiology to third-year medical students during confinement due to the current Covid-19 pandemic. In general, the students, who are digital natives nowadays, have found it easy to adapt to the use of the 3D platform. Although there have been some technical limitations, both students and teachers involved have rated the use of Second Life® during the confinement very highly.

Nine professors of radiology from six different cities were invited to give a 1-hour seminar in the virtual world Second Life® to 154 third-year medical students from the University of Málaga. Students and teachers performed a questionnaire about the cognitive load that implies receiving/teaching seminars inside Second Life@ and several characteristics involving the experience. This experience was considered remarkably enriching by teachers and learners and opens new interesting pathways for educational contact between students and teachers from different universities, with the advantages of reducing costs and travel time.

A competition-based game, named League of Rays (LOR), designed to learn radiology within the multi-user virtual environment Second Life was adapted for the participation of teams of four students. The game ran from 20 February to 1 April 2020. Forty-one teams from 16 universities initially signed up and 28 teams from 14 universities finished the game. Participants found this activity fun, enjoyable and useful for their training. Some interesting proposals to be included in future editions of the game and interesting comments on the meaning of developing half of the game during the confinement caused by the Covid-19 pandemic were provided from participants.
