Objective:
To compare diagnostic accuracy using conventional versus monitor-displayed medical images in order to determine if years of experience as a board-certified clinician influences diagnostic performance in either modality.
Materials And Methods:
In separate observer performance studies, six radiologists and six pathologists differing in years of experience viewed clinical images, once in the conventional modality (X-ray film or light microscopy) and once using a monitor display. Readers also were surveyed regarding their experience with digital/video display systems.
Results:
In both studies, performance was similar for conventional and monitor modalities. For the conventional displays, there was a positive correlation between years of clinical experience and performance. For the monitor displays, however, there was a strong negative correlation between years of clinical experience and performance. Performance using the monitor displays correlated highly with experience using digital/video systems in general.
Conclusion:
More exposure to and use of monitor displays, such as recreational video games and computers, may influence positively the clinician-monitor display system interaction and improve diagnostic performance.
