The Financial and Environmental Benefits of Circular Business Models for MRI.

Abstract

The aim of this study was to compare the total cost of ownership and environmental impact of linear and circular MRI business models at an academic medical center in the United States. The authors compared replacing an existing MRI scanner with a conventional linear business model (purchasing a new scanner) and two circular business models (purchasing an on-site upgrade or a refurbished scanner). The impact of these business models on total cost of ownership for the hospital was assessed. In addition, greenhouse gas (GHG) emissions and materials used (kilograms) were compared using data from a life cycle assessment. Compared with a conventional linear purchase of a new MRI scanner, circular business models reduced (1) total cost of ownership by up to 21%, (2) GHG emissions by up to 8% when using a conventional energy grid and 37% when using a clean energy grid, and (3) material use by up to 92%. Upgrading an existing scanner on site delivered the most beneficial gains, driven primarily by the reuse of critical components. This study highlights the potential value of circular MRI business models for hospitals, patients, and the planet. By embedding innovative procurement strategies, imaging centers can deliver care with less cost while reducing GHG emissions and saving critical materials. The authors recommend that hospitals consider upgrading existing MRI scanners on site or purchasing refurbished scanners before pursuing replacement with entirely new ones. The authors also encourage further investigation into the financial and environmental benefits for other imaging equipment.
