flag Turning off hospital CT scanners during off-hours cuts energy use, costs, and emissions without harming care.

flag CT scanners in hospitals use more energy than an average household, but turning them off during off-hours and weekends significantly cuts energy use, costs, and emissions without harming patient care, according to a study involving multiple hospitals. flag Researchers found that shutting down one scanner when not in use reduced power consumption to levels comparable to a typical home, with no negative impact on workflow or emergency readiness. flag The practice has been adopted at several hospitals, part of a broader push to make healthcare more sustainable by reducing emissions from imaging, anesthesia gases, pharmaceutical waste, and single-use supplies. flag Frontline staff, supported by research, are driving these changes, proving that high-quality care and environmental responsibility can coexist, advancing global efforts toward net-zero healthcare systems.
