Medical imaging techniques like radiography and fluoroscopy have a measurable environmental impact, primarily due to energy use and associated emissions. This study assessed the carbon footprint of these imaging services at a large academic medical center over one year using life cycle assessment (LCA) methods, collecting data through observations, records, staff interviews, and energy metering.
The analysis estimated that radiography and fluoroscopy generated about 55,100 kilograms of CO鈧� equivalent annually. Energy use was the largest contributor, responsible for 47% of emissions. Per-scan emissions were higher for fluoroscopy (4.8鈥�9.6 kg CO鈧俥 per scan) compared to radiography (0.8 kg CO鈧俥 per scan). Medical linens contributed 24% of total emissions, and additional environmental effects included ozone depletion, smog, acidification, and eutrophication.
The study highlights that reducing energy consumption鈥攖hrough decarbonized electricity and optimized equipment use鈥攃an significantly cut greenhouse gas emissions. Sustainable management of linens, responsible procurement, and minimizing unnecessary imaging are also important strategies for lowering the environmental footprint of radiography and fluoroscopy.
