Radiographers often prioritize image quality and experience over research-based evidence when modifying imaging techniques. This reliance on experience may lead to outdated practices and suboptimal patient outcomes in diagnostic radiography.
Area of Science:
- Radiologic Technology
- Medical Imaging
- Evidence-Based Practice
Background:
- Evidence-based practice (EBP) in radiography is crucial but underdeveloped.
- Radiographers' imaging technique decisions are influenced by education and experience, not always research.
- Lack of EBP engagement may lead to outdated practices and poorer patient outcomes.
Purpose of the Study:
- To investigate the motivators and influences on radiographers' decisions regarding imaging acquisition techniques.
- To understand why research-based evidence is not always prioritized in radiographic practice.
Main Methods:
- An exploratory, descriptive qualitative study using semi-structured interviews.
- Convenience sample of 12 radiographers from three public hospitals in Queensland.
- Thematic analysis was employed to analyze interview data.
Main Results:
- Five key themes emerged: technology, experience over evidence, radiology's influence, information sources, and image quality.
- Image quality was the primary driver for technique modification.
- Radiographers frequently relied on empirical observations and experience, not routine research engagement.
Conclusions:
- Excluding research-based evidence can result in ineffective clinical decisions.
- Further research is needed to advance radiography.
- Enhancing radiographers' willingness and capacity for EBP is essential for improved practice and patient care.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
