Key research themes
1. How do Diagnostic Reference Levels (DRLs) optimize patient radiation exposure during diagnostic radiography?
This theme encompasses research on the establishment, use, and refinement of diagnostic reference levels (DRLs) as tools for optimizing radiological protection by managing radiation doses in medical imaging. DRLs are not dose limits but serve as benchmarks to identify unusually high or low radiation doses, thereby promoting dose optimization in diagnostic and interventional radiography while maintaining clinical image quality. Continued development addresses terminology clarification, updates for evolving imaging technology, and implementation strategies.
Key finding: This work clarifies the definition and application of DRLs, introducing terms like 'DRL quantity' and 'DRL value'. It recommends the use of facility median values for DRL quantities to better represent patient populations and... Read more
2. What are the barriers and facilitators for effective knowledge and skills transfer between diagnostic radiographers and students in clinical radiography practice?
This research area investigates the dynamics of knowledge and skills transfer in clinical settings between qualified radiographers and students, which is critical for effective professional training and patient care. Studies focus on identifying enablers such as conducive environments and learning preferences, as well as barriers like communication gaps, supervision challenges, workplace pressures, and interpersonal factors, to propose solutions for improving educational outcomes in diagnostic radiography.
Key finding: Through qualitative interviews with radiographers and students, this study identifies major enablers including a safe work environment and personal attributes, and significant barriers such as communication difficulties and... Read more
3. How can evidence-based radiology improve decision-making and reduce unnecessary diagnostic imaging in radiography practice?
This theme comprises work on applying the principles of evidence-based radiology (EBR) to optimize patient management, reduce unnecessary imaging and radiation exposure, and improve resource utilization. Research emphasizes critical literature appraisal, formulation of clinically relevant questions, and integration of best evidence with clinical expertise and patient values to guide optimal imaging choices.
Key finding: This paper articulates the five-step EBR process—question formulation, efficient literature search, critical evaluation, application considering clinical experience and patient expectations, and practice evaluation—and... Read more
