Implication
Randomized trial compares image quality and breast dose in digital versus screen-film mammography systems, suggesting enhanced performance of digital technology.
Key Points
- This research aims to evaluate the performance differences between full-field digital mammography and screen-film mammography systems in clinical settings.
- Conducted acceptance testing on 18 digital mammography systems and annual surveys of 38 screen-film mammography systems.
- Assessed exposure times, mean glandular breast doses, and image quality using standardized test tools.
- Focused on automatic exposure control and contrasted performance across different breast thicknesses.
- Digital mammography systems exhibited shorter exposure times and lower mean glandular doses for thicker breasts while performing similarly for thinner breasts.
- For all breast thicknesses, digital systems achieved higher mean contrast-detail scores compared to screen-film systems.
- Digital mammography demonstrated less variability in exposure times and image quality scores across all thicknesses than screen-film systems.
