Advancing circular economy practices in radiography: a narrative review of sustainable medical imaging
Abstract
Background and Objective: The healthcare sector, particularly radiography, plays a notable role in environmental degradation due to high energy consumption, resource-intensive manufacturing, and significant electronic waste (e-waste). Circular economy (CE) principles, centred on reducing waste, extending equipment lifecycles, and improving recycling, offer a promising framework for promoting sustainability in radiographic practice. This literature review employs a narrative synthesis approach informed by systematic search methods to explore CE principles, waste reduction, lifecycle extension, and improved recycling, as a framework for promoting environmental sustainability in radiographic practice whilst maintaining diagnostic quality. Methods: This review employed a narrative synthesis approach with systematic search methodology to explore the integration of CE practices in radiography. Peer-reviewed articles, industry reports, and case studies from 2018 to 2024 were analysed using structured database searches across PubMed, Scopus, and IEEE Xplore (127 articles screened, 89 included) to identify key themes, challenges, and emerging innovations. Key Content and Findings: Findings reveal that CE applications in radiography are gaining traction through sustainable equipment design, energy-efficient technologies, modular components, and end-of-life recycling strategies. Quantitative analysis shows that artificial intelligence (AI)-driven imaging solutions can reduce scan times…
