Researchers open-source 'Lost in k-Space' escape room to teach MRI physics

Operating an MRI scanner demands more than physics knowledge — it requires safety management, teamwork, and quick thinking under pressure. To teach those skills, researchers from the ESMRMB community developed 'Lost in k-Space,' a gamified MR-physics escape room presented at the 41st Annual Meeting. The room recreates an MRI control room atmosphere where teams of four work against a 25-minute clock. Five puzzles challenge players on the Larmor equation, sequence composition, MR safety, and acoustic identification of MRI sequences. Behind the scenes, custom ESP32 microcontrollers let each puzzle communicate in real time with one another and with a game master, allowing dynamic hints and score tracking.

The results were impressive: 39 teams — roughly 160 participants — played the room without any technical interruptions. Only 12 teams escaped (31% success rate), with a median solution time of 21 minutes and 53 seconds. This escape rate matches comparable educational escape rooms for scientific audiences, and the difficulty can be tuned by adjusting puzzle obscurity, required prior knowledge, and component availability. The authors suggest a modified version could supplement mandatory MR safety training. Crucially, the entire project — code, schematics, machining files, and documentation — is released as open source on arXiv (arXiv:2608.09616), enabling any institution to build their own MR-physics escape room.
