Immersive virtual reality for pre-registration computed tomography education of radiographers: A narrative review

To be registered as a medical radiation practitioner, The Medical Radiation Practice Board of Australia (MRPBA) requires radiographers to be capable of performing computed tomography (CT) imaging examinations safely and effectively. Universities meet this requirement by offering practical CT training to radiography students on-campus and during clinical placements. However, institutions face challenges when facilitating on-campus CT practicum. Virtual reality (VR) has been suggested as a possible solution for radiography students to gain CT scanning experience. This narrative review explored relevant literature to investigate the potential for immersive VR to be incorporated into CT practicum. Benefits and limitations of this education technology are examined with resultant recommendations made for integration into the CT curriculum. Results found that VR enhances CT learning for students, increases confidence and raises motivation for the simulated CT task. CT simulation provides a viable alternative in the context of pandemic-imposed restrictions and reduced CT placement duration. However, it remains debatable as to whether immersive VR truly enhances student learning compared with other VR modalities, such as computer-based CT simulation. In addition, a lack of staff training, availability of resources and technical problems were flagged as limitations. We concluded that before immersive VR is integrated into CT education, significant optimisation of the simulation is needed. This includes ensuring VR scenarios are based on learning paradigms and feedback is integrated as part of simulation learning. Engaging clinical partners during the CT VR rollout is imperative to ensure successful transition of students from university learning to clinical placement.
