What was done
The authors presented an educational review focusing on the first two steps of the standard five-step evidence-based practice framework adapted for radiology. They described methods for formulating answerable clinical questions (step 1) across diagnostic and interventional radiology and demonstrated search strategies to retrieve evidence from the biomedical literature (step 2) using a diagnostic clinical scenario.
What was found
The abstract reports no empirical data, statistical analyses, or quantitative findings. It provides a conceptual overview and illustrative clinical example demonstrating how to construct searchable clinical questions and identify relevant evidence sources in radiology.
Why it matters
It translates core evidence-based medicine principles into practical workflows for radiologists to improve literature retrieval and support clinical decision-making.
Limits
This is a narrative, instructional article rather than an empirical trial or systematic review. It provides no quantitative evaluation of whether following these steps improves search accuracy, diagnostic performance, or patient outcomes.
