Screen-film mammographic density and breast cancer risk: a comparison of the volumetric Standard Mammogram Form and the Interactive Threshold Measurement Methods

摘要

Background:Mammographic density is a strong risk factor for breast cancer, usually measured by an area-based threshold method that dichotomises the breast area on a mammogram into dense and non-dense regions. Volumetric methods of breast density measurement, such as the fully-automated Standard Mammogram Form (SMF) method that estimates the volume of dense and total breast tissue, may provide a more accurate density measurement and improve risk prediction.
