1 The responsibilities of a radiation therapist supporting MRI-guided High Dose Rate Brachytherapy for Prostate Cancer Jessy Abed 1, Amanda Bolderston 1, 2, Caroline Davey 1, Tara Rosewall 1, 2, Dr. Cynthia Menard 1, 2 1. Radiation Medicine Program, Princess Margaret Hospital, Toronto, Canada 2. Department of Radiation Oncology, University of Toronto, Toronto, Canada INTRODUCTION 1) Brachytherapy: –achieves better therapeutic ratio for prostate cancer –demands higher precision 1 2) MRI guidance provides the best visualization of the prostate 2 3) Interventional MRI (iMRI) improves treatment quality for HDR prostate brachytherapy (HDRpb) –also requires supporting processes –may provide an opportunity for RTT role expansion This poster presentation: –Outlines MRI-guided HDRpb process –RTT role responsibilities –RTT educational requirements METHODS Retrospective case study Research environment: –Large Canadian teaching hospital –Operational permanent prostate implant program –MRI scanner dedicated to RT –No prior institutional experience with either HDRpb or iMRI Researcher: –BSc-prepared RT –2-years experience –Clinical placement in brachytherapy –Dedicated research role in this project

Department of Radiation Oncology, University of Toronto, Toronto, Canada CONCLUSIONS iMRI-HDRpb procedure is still experimental, yet early results are promising The procedure: –is novel and complex –has created an interesting opportunity for RT role expansion This opportunity provides a new avenue for RTT career diversity Must be supported by significant professional development efforts REFERENCES Menard, C., R.
