Benefits and challenges of the new MR Linac service implemented at the local oncology department : a radiographers’ perspective

Abstract

Purpose: This study aimed to investigate the perception of the radiographers on the benefits and challenges associated with the introduction of the magnetic resonance linear accelerator (MR Linac) at the local oncology hospital. Methodology: All radiographers working at the local oncology department were invited to complete a self-designed questionnaire consisting mostly of Likert scale questions ranging from 1 to 5 and some open-ended questions. The radiographers were asked to rate the benefits and challenges of the MR Linac for specific areas. In addition, the radiographers were also asked to indicate their confidence in performing specific tasks, their perceptions on a radiographer-led workflow, and the additional resources required to improve the services. Finally, the radiographers were asked to indicate their confidence in performing specific tasks on the MR Linac and their views on introducing a radiographer-led workflow. The quantitative data was summarized using descriptive statistics, while the open-ended questions were analysed using content analysis. Results: Out of the 26 invited radiographers, 15 completed the questionnaire. The use of ultra-hypofractionation and the reduction of dose to the healthy OARs were identified as the main benefits of this technology, while the prolonged treatment time was identified as the main barrier. The overall level of confidence using the MR Linac was 2.73 +/- 1.22. The radiographers were least confident in managing technical and safety issues and most confident in positioning patients. The majority of the radiographers (53.3%) agreed that a radiographer-led workflow could improve treatment efficiency, provided that this was introduced gradually following adequate training. Contouring software based on artificial intelligence was identified by most radiographers as required to streamline the workflow. Conclusion: Despite challenges faced, radiographers expressed optimism about the integration of this technology in practice. However, more training is required to improve service delivery and facilitate the introduction of a radiographer-led workflow.
