In 2022, costs for optimized protocols ranged from EUR 0.17 to EUR 0.90, while those for standard protocols were between EUR 0.42 and EUR 1.28 per scan. In 2023, standard protocols were priced between EUR 2.86 and EUR 12.57 per scan, whereas optimized protocols cost between EUR 1.94 and EUR 8.87 in electricity expenses. Dual optimization: utilizing optimized protocols and MRI exam scheduling with winter electricity pricing. Figure 5 shows the MRI exam timeline, and Table 4 lists energy consumption and costs. The first optimization was to identify a sequence for the standard protocol, taking into account accommodates constraints related to changing antennas, hourly pricing, the need for breaks between protocols, and the absence of injections at the beginning and end of the day. Subsequently, within the same time window and the same constraints, the incorporation of SmartSpeed AI into our optimized imaging protocols enabled the completion of an additional five neurovascular and six knee protocols. The total energy consumption for the MRI protocols was measured at 296.03 kW for 41 optimized protocols and 330.95 kW for 30 standard protocols. The operational window for optimized protocols includes more standby periods, amounting to 61.50 kW, compared to 45 kW for breaks in standard protocols. In the daily operational window, the cost analysis for 2021 and 2022 indicates that the total cost of running standard protocol sequences, including breaks, was EUR 22.53 and EUR 25.48, respectively. For optimized protocols, the corresponding costs were EUR 20.15 and EUR 22.78.
