Prospective Evaluation of the Carbon Footprint and Clinical Utility of IBUS Compared to Colonoscopy and Enterography in UC and CD

Healthcare contributes approximately 4.4% of global GHG emissions, with diagnostic imaging and endoscopic services being substantial contributors. Colonoscopy and cross-sectional imaging modalities, though indispensable, are associated with high carbon emissions due to electricity use, waste, sterilisation, and transportation. IBUS, a non-invasive, real-time diagnostic modality, is increasingly validated for disease activity assessment in both UC and CD.
