MRI Fleet Recordings Reveal Idle Modes Drive Majority of Energy Use, Pointing to Duration-Focused Efficiency Gains

Preprint analysis of continuous MRI fleet energy data shows idle modes consume more total energy than scanning; duration emerged as the dominant variable. The work supplies a replicable baseline for sustainability interventions in high-use diagnostic imaging.

If hospitals translate these findings into scheduling and sequence optimization, operational costs and carbon footprints could fall without new capital expenditure. Follow-on work should test whether duration-targeted interventions produce measurable reductions in prospective trials across varied health-system settings.

⚡ Prediction

Raab et al.: Hospitals implementing duration-optimized protocols will record at least 15% lower annual MRI energy use within 18 months of adoption.
