In comparison with analogue film, digital mammography provides images with more contrast and allows image manipulation. This study compares features identified on digital and analogue mammograms.
During the transition to digital mammography between June and August 2011, women who had received analogue screening mammography and required further views at assessment had repeat digital images. Eight readers reviewed digital and analogue images separately, marking all features that caught their attention on a pro forma. Readers commented on breast density and characterised all features using BiRads descriptors.
Aggregate features identified (number of times features were marked)
This study showed that readers reported breasts as less dense and identified fewer distracting soft tissue lesions on digital mammography but there was no difference in the reporting of calcifications. One of six cancers was under-reported on digital mammography.
