Optimisation toward sustainable computed tomography imaging practices

Abstract

To assess the optimisation impact on the trajectory towards sustainable Computed Tomography (CT) imaging practices, technical parameters, and volume computed tomography dose index (CTDIvol) were collected for abdominal pain and diverticulitis/appendicitis clinical indications at Salamniya Medical Complex before and after optimisation of imaging protocol. Post-optimisation evaluation revealed a significant reduction in CTDIvol, accompanied by a total reduction of 100 kg in carbon dioxide equivalent emissions and an annual cost savings of 20 $. These changes positively influence social, environmental, and economic pillars of sustainability, respectively. The long-term optimisation across multiple hospitals will support the transition towards sustainable CT imaging practices in Bahrain.
