摘要

综述目的:本综述旨在强调在泌尿外科实践中经常被忽视的医学成像对环境的影响,重点是能源消耗,相关的碳排放,以及减少成像方式碳足迹的实用策略。最近的研究发现:医学成像占医院总能源使用的很大比例,其中MRI、CT和PET-CT是最耗能的方式。最近的生命周期评估发现,能源使用占放射科温室气体(GHG)排放的一半以上。成像系统,如透视和超声也有意义的贡献,特别是当闲置功耗被忽视。新的数据显示,简单的干预措施,如在非操作时间关闭成像设备,减少不必要的成像,可以减少20-70%的非操作能源消耗。摘要:由于开发周期长,节能成像系统的采用速度缓慢,因此必须通过改变操作来立即减少排放。优化调度、缩短方案、减少低价值成像和关闭未使用设备等策略可以显著减少碳排放和成本,同时不影响诊断价值。转诊临床医生和放射科医生之间的合作对于推动这一转变至关重要。

The carbon footprint of modern imaging.

Purpose of review: This review aims to highlight the often-overlooked environmental impact of medical imaging in urological practice, focusing on energy consumption, associated carbon emissions, and practical strategies for reducing the carbon footprint of imaging modalities.

Recent findings: Medical imaging accounts for a significant proportion of a hospital's total energy use, with MRI, CT, and PET-CT being the most energy-intensive modalities. A recent life cycle assessment found that energy usage accounted for over half of a radiology department's greenhouse gas (GHG) emissions. Imaging systems such as fluoroscopy and ultrasound also contribute meaningfully, particularly when idle power consumption is overlooked. New data reveal that simple interventions, such as shutting down imaging devices during nonoperational hours and reducing unnecessary imaging, can cut nonoperational energy use by 20-70%.

Summary: Given the slow adoption of energy-efficient imaging systems due to long development cycles, immediate emission reductions must come from operational changes. Strategies such as optimizing scheduling, shortening protocols, reduction of low-value imaging and powering down unused equipment can significantly reduce carbon emissions and costs - without compromising diagnostic value. Collaboration between referring clinicians and radiologists is critical to driving this transition.
