Purpose We report our initial experience with the Getinge Pilot System, initially designed for neurosurgery, after it was modified to be used in a brachytherapy suite. The objective was to develop a workflow integrating Magnetic Resonance Imaging (MRI) and standard Computed Tomography (CT) for each GYN brachytherapy fraction without compromising patient access and minimizing motion. Materials and Methods The first 100 GYN brachytherapy fractions treated in the new facility were included in this analysis. The duration of each step of the procedure was acquired for every patient. Based on the available information, modifications were incorporated into the workflow to optimize the procedure and gain efficiency. Our analysis is focused on 2 specific steps of the procedure: preparation and transfer to the MRI (once the insertion of the applicators is completed and the patient is moved to the MRI) and the time between the end of the MRI and the completion of CT planning (transfer to a different room and completion of CT Scan). In order to evaluate the impact of the learning curve with this new technology, we analysed the average time of the first three fractions separately and compared it with the following 97 fractions. Results Fig.1 We observed a 56% reduction in the average time to complete the preparation and transfer to the MRI portion of the procedure over time, going from an average of 27 minutes for the first three fractions to an average of 12 min for the next 97 fractions (3-25 minutes). A similar reduction of 42% was observed for the time interval between the end of the MRI and the completion of CT, going from an average of 24 minutes for the first three fractions to 14 minutes (7-40 minutes) for the subsequent 97 fractions. Conclusions The time associated with the addition of MRI for every fraction and patient transfer from one room to the other was significantly reduced after adjustments were made to optimize the workflow. This new, time efficient workflow using the Getinge Pilot system allowed us to incorporate daily MR Imaging to standard CT treatment planning in GYN brachytherapy without a reduction in the number of cases treated on a daily basis compared to MR imaging only for the first fraction. The Getinge system, although it was designed for neurosurgery, is very well suited to the reality of brachytherapy interventions with multiple imaging.
