Reflective practice guidance
The guidance below is provided to support reflection at different time points, providing you with questions to aid you to reflect for this training activity. They are provided for guidance and should not be considered as a mandatory checklist. Trainees should not be expected to provide answers to each of the guidance questions listed.
Before action
- What are the intended outcomes of the training activity?
- How will you develop the ability to critically evaluate the specific strengths and weaknesses of different diagnostic x-ray modalities?
- How will you demonstrate an understanding of the crucial link between a specific clinical question and the required image quality characteristics needed to answer it?
- What do you anticipate you will learn from the experience?
- How do you anticipate the fundamental physics principles of projection radiography, fluoroscopy, and CT will influence the achievable spatial resolution, contrast, and noise in each modality?
- In what ways do you expect to learn how to compare image quality both quantitatively and qualitatively?
- How do you anticipate this experience will improve your ability to scientifically justify the selection of a particular modality based on benefits, limitations, and clinical requirements?
- What actions will you take in preparation for the experience?
- How will you structure your discussion with your Training Officer to identify the specific modalities and clinical applications you will be comparing?
- Which educational resources will you review to deepen your knowledge of the principles and image quality characteristics of various diagnostic systems?
- What clinical scenarios will you research to understand why one modality might be preferred over another for a specific diagnosis?
- How do you feel about the challenge of developing a deeper, evidence-based understanding of modality selection?
In action
- What specific diagnostic x-ray imaging modalities are you currently comparing?
- What are the key image quality parameters for each?
- How are you assessing the relative benefits of each modality for a given clinical application? What factors are you considering?
- How are you relating the specific image quality needs of the clinical application to the strengths and limitations of each modality?
- Which aspects of this assessment feel more grounded in your understanding of the technical principles of each modality, and which require a more nuanced understanding of clinical needs?
- How effectively are you able to differentiate the image quality characteristics of the chosen modalities?
- What challenges are you facing in quantifying the relative benefits or in clearly linking image quality parameters to specific clinical outcomes?
- What are you learning about the appropriate selection of imaging modalities based on clinical need and image quality requirements?
- How does this activity connect to your broader understanding of diagnostic radiology practice and the impact on the patient pathway?
- Are there alternative clinical scenarios or image quality parameters you should consider in your comparison?
- Do you need to consult clinical guidelines or research literature to support your assessment of relative benefits and clinical applications?
- Are you clearly articulating the trade-offs between different modalities in terms of image quality, dose, and availability?
On action
- What diagnostic imaging modalities were compared?
- What specific image quality parameters were assessed for each modality?
- What were the relative benefits and limitations of each modality in terms of image quality?
- How were the image quality needs related to specific clinical applications?
- What trade-offs exist between different image quality parameters and modalities for different clinical scenarios?
- What did you learn about the key image quality parameters for different diagnostic x-ray modalities (e.g., radiography, fluoroscopy, CT)?
- What are the relative strengths and weaknesses of these modalities in terms of image quality for various clinical indications?
- What did you learn about how to determine the appropriate imaging modality based on the specific clinical question and the required image quality?
- What did you learn about the concept of ‘fitness for purpose’ in diagnostic imaging.
- How will you approach modality selection in different clinical scenarios?
- What factors related to image quality will you consider when discussing imaging options with referrers or other professionals?
- How will you continue to develop your understanding of the clinical applications of different imaging modalities?
Beyond action
- Have you had further opportunities to compare image quality parameters and assess the relative benefits of different modalities for various clinical applications since this training activity? How has your understanding evolved?
- Consider the specific modalities and clinical applications you assessed. Have you revisited the literature or guidelines related to these comparisons?
- Have you discussed modality selection and image quality requirements with radiologists or other referring clinicians? Did these discussions provide new insights into their perspectives?
- How has this activity enhanced your ability to understand the strengths and limitations of different diagnostic radiology modalities in relation to specific clinical questions?
- Has this experience influenced your understanding of the importance of tailoring imaging protocols to meet the specific diagnostic needs?
- Consider how this activity has shaped your appreciation for the trade-offs between different image quality parameters and their impact on diagnosis.
- Identify how your skills in assessing the relative benefits of different modalities and understanding the link between image quality and clinical application will be crucial for effective imaging strategy and multidisciplinary communication in your future role.
- What actions will you take to continue developing your knowledge of the clinical applications and relative benefits of different diagnostic radiology modalities?
