Transforming Challenges into Training Resources: Establishing a Sustainable FDG Production System with Radiology Technologist Education

In-house production of FDG is increasingly necessary to ensure a stable supply of PET tracers. However, the establishment of new production facilities is often accompanied by unforeseen technical challenges. Transforming such challenges into educational experiences may play an important role in developing skilled radiology technologists. In-house FDG production training that incorporates real-world troubleshooting cases fosters skilled and confident technologists. This study aimed to evaluate the effectiveness of an educational approach that integrates real-world troubleshooting experiences encountered during the establishment of an FDG production system into training for radiology technologists. <b>Methods:</b> At our newly launched theranostics center, 4 radiology technologists were trained to perform FDG synthesis using a cyclotron and an automated synthesis module. Challenges encountered in the early phase (e.g., cassette-loading errors, errors in gas supply operation, mistakes in handling reagents) were systematically documented. These cases were incorporated into training manuals, simulation sessions, and on-site drills. Educational outcomes were evaluated qualitatively through feedback, competency assessments, and operational stability. Radiation exposure was monitored as a supplemental safety measure. <b>Results:</b> The documentation and sharing of early-stage troubleshooting cases facilitated the development of practical manuals and scenario-based simulations for FDG production. Radiology technologists demonstrated improved confidence and decision-making in handling synthesis tasks. The FDG production process achieved stable operation within several months. Occupational doses for technologists remained well below regulatory limits, supporting the safety of the training approach. <b>Conclusion:</b> Educational use of early troubleshooting experiences effectively enhanced radiology technologists' competencies in FDG production. This strategy provides a sustainable model for workforce development in nuclear medicine facilities worldwide.
