COMPARISON OF OLDER AND NEWER GENERATION MRI AND ASSESSING ROLE OF WORKFLOW OPTIMIZATION IN ENERGY SAVING IN IMAGING. AN EXPERIENCE IN NORTH INDIA

Motivation: Cost effectiveness of New Generation MR units versus older unit and role of workflow optimization Goal(s): Our goal was to evaluate two similarly specced 3T MR systems of different generations and the effectiveness of the low power mode in new generation scanners in overall cost reduction Approach: Retrospectively compared power savings between an older and new generation MR units and optimized workflow towards the efficient newer unit Results: Significant annual savings in energy consumption in direct comparison between two units (~23%) with scope of further savings of workflow optimization towards new generation unit. Impact: New generation MR Units are efficient than older generation models with manufacturer enabled low power mode. Optimizing workflow and judiciously managing the low power mode results in significant decrease in long term energy costs without need for expensive software such as AI hardware modifications and goes a long way, especially in developing countries
