Teaching Strategies in Interventional Radiology: A Narrative Review of the Literature

IntroductionInterventional radiology (IR) is a rapidly developing speciality where innovation-especially in teaching practices-is vital. With workforce and capacity shortages, synthesis of classical educational theories and novel strategies utilising virtual reality (VR) and artificial intelligence (AI) provide opportunities to make teaching as efficient and effective as possible. The aim of this review is to examine the literature on different approaches in IR teaching and learning in undergraduates and postgraduates.MethodsLiterature was reviewed using a comprehensive search strategy with relevant keywords. Articles were limited to 2013-2023. Databases searched included MEDLINE, Embase, British Education Index and ERIC, in addition to a manual review of references.ResultsOf the 2903 unique abstracts reviewed by the authors, 43 were relevant to the purpose of this study. The major pedagogical approaches identified were categorised into the following-traditional master-apprentice mentoring, virtual reality/simulation, physical models, and remote teaching. VR simulations enable practise free from the limits of time and risk to patients, as well as potential for standardised formal curricula. AI has the capability to enhance training simulations and assessment of trainees. With recent events necessitating innovation in online remote teaching, programs that are accessible whilst arguably imparting just as much clinical knowledge as in-person education have now been developed.ConclusionMentoring has conventionally been the standard for radiology teaching, however there are now several alternative pedagogical approaches available to the IR community. A combination of the most effective ideas within each is the optimal method by which IR should be taught.
