A new model of the infusion system (model 1700) with automated daily quality control procedures (DQC) may reduce time and occupational radiation exposure (ORE) is under late-stage regulatory validation. We sought to determine changes in operational efficiency and ORE to Nuclear Medicine Technologists (NMT) between the new model 1700 and old model 510 CardioGen rubidium-82 infusion systems. Methods: Ten NMTs performed DQC on both models of the infusion system daily over a 30-day period. Instadose whole-body and ring badges were worn by each NMT while performing DQC procedure to monitor staff radiation exposure. Operational efficiency between the two infusion systems was compared by the NMT documenting the length of time to complete the DQC procedure. Data was represented by mean ±SD. Paired sample t test was used to evaluate the DQC procedure time. Results: The figures below compare ORE and DQC time between the two infusion systems. Figure A: There was no difference in the whole-body ORE (5 vs. 5 mrem) and ring badge exposure (95 vs. 97 mrem; N=10) between the model 1700 and 510 systems. However, there was a significant reduction in average DQC time (40±9.4 vs. 83±5.6 min; P=&lt;0.0001= N=10) for the new model 1700 system. Conclusions: The new CardioGen rubidium-82 model 1700 has an over 50% reduction in average DQC procedure time with similar radiation exposure. This suggests the new model 1700 may facilitate more efficient laboratory workflow.
