Similarly, the median DA was larger by 1. Because processing may suppress or enhance image features such as dense tissue, MD measurements may systematically differ between the original raw and the processed images. Background Mammographic density MD , a measure of the radiodense tissue in the breast, is a strong marker of breast cancer BC risk [ 1 ]. Differences between SFM and CR-digital images appeared to be small, although the latter were not time-matched comparisons. Methods We obtained pairs of images saved in both raw and processed formats from Hologic and General Electric GE direct digital systems and a Fuji computed radiography CR system, and screen-film and processed CR-digital pairs from consecutive screening rounds. Personalizing mammography by breast density and other risk factors for breast cancer: analysis of health benefits and cost-effectiveness.
