Within diagnostic imaging departments, however, consumer perspectives remain under-represented in workplace education and continuing professional development (CPD), where educational activities have traditionally prioritised technical competency and workflow. This is despite the fact that clinicians frequently meet patients at vulnerable moments. This paper describes how a tertiary imaging department embedded consumer engagement across workplace education and CPD, governance and service improvement, and outlines practical lessons for departments wishing to implement similar initiatives. It draws on a series of initiatives undertaken within a tertiary imaging department between 2024 and 2025, including consumer storytelling within multidisciplinary workshops and continuing professional development, consumer co-design of patient information resources, a dedicated patient-experience role, and consumer participation in departmental governance. We considered these activities alongside established frameworks for patient involvement in health-professions education and for consumer participation, and we reflected on the practical conditions that distinguish meaningful engagement from tokenism: clarity of purpose, attention to consumer wellbeing, and a shift from symbolic inclusion towards genuine partnership. The activities are illustrated with feedback volunteered by clinicians and consumers, although we are careful to note that these reflections are not a formal evaluation. We argue that consumer storytelling and structured engagement are feasible, low-resource strategies that may promote reflection on empathy, communication and patient-centred practice, while offering practical approaches for embedding consumer engagement within imaging departments. Formal evaluation of educational and patient outcomes remains the necessary next step.</p>","PeriodicalId":16382,"journal":{"name":"Journal of Medical Radiation Sciences","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13535535/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148874438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, high failure rates during breath-hold simulations have been associated with patient anxiety and insufficient preparation—particularly when instruction is given only 20 min prior to the procedure. These challenges are amplified for patients from culturally and linguistically diverse (CALD) backgrounds. To address this, a multilingual mobile application (app) has been developed to improve patient education, communication, and compliance, with a particular focus on supporting CALD patients. Replacing traditional pamphlets with interactive instructional videos, visual aids, and real-time translation in seven languages, the app allows patients to familiarise themselves with breath-hold techniques before their Computed Tomography (CT) simulation. A General Radiation Therapy (RT) section in the app further supports communication between radiation therapists (RTs) and their patients by providing translated commands for standard patient positioning and movement instructions, improving accuracy and workflow efficiency. The app integrates with in-room sound systems, allowing RTs to provide remote coaching while maintaining clear and consistent communication. Additionally, the Frequently Asked Questions (FAQ) section of the app addresses common concerns that patients have about radiation therapy, helping them gain a better understanding with the possibility of reducing anxiety.

The radiography discipline is well positioned to explore the benefits and limitations of these technologies. This article presents a narrative review and conceptual synthesis of emerging evidence on the use of generative artificial intelligence in radiography education. Drawing on emerging radiography-specific studies, the paper synthesises evidence relating to image critique, professional communication training, simulation-based learning, CPD planning and reflective practice. Evidence suggests that ChatGPT can provide structured guidance, support self-assessment and scaffold learning processes that bridge classroom knowledge and clinical expectations. In image evaluation tasks, generative AI may identify broad positioning and exposure issues and prompt metacognitive reasoning when learners are encouraged to critically appraise its outputs. In communication tasks, AI systems can offer structural support but consistently lack the relational nuance essential for safe clinical interactions. In reflective tasks, AI-generated reflections typically lack emotional depth, professional and ethical insight and accountability. Furthermore, custom AI-driven simulations show promise as tools for safe experimentation; however, their outputs commonly default to technically correct responses that provide limited contextual or professional insight. These findings suggest that the value of generative AI lies in how it is pedagogically framed. Rather than advancing algorithmic or performance-based claims, this paper interprets generative AI as a pedagogical artefact whose educational value is contingent on framing, educator oversight and learner critical engagement. The review integrates fragmented evidence with educational theory and professional regulation and proposes a conceptual framework for the responsible integration of generative AI in radiography education.
