Medical imaging is one of the biggest contributors of a hospital’s energy use. Magnetic resonance imaging (MRI) and computed tomography (CT) are particularly carbon intensive, partly due to their need to be constantly cooled. Hospital staff typically leave these machines running 24/7 because they’re often needed for emergency scans.
But do all machines really need to be kept on all of the time? Switching off medical imaging equipment when it isn’t needed would be an obvious way to save energy, costs and reduce carbon emissions.
