Breast density is a major risk factor of breast cancer,
and is usually assessed visually from mammograms. This
has two main disadvantages: there is not a standard
measure of breast density, as the breast is classsified
in qualitative categories, and this assessment does not
consider that mammography is a 2D projection of the
breast volume. We developed a method to quantify
volumetric breast density from mammograms and a
semi-automatic method that quantifies this measure in 3D
breast MRI. Thus, it is possible to obtain an equivalent
quantitative measure of breast density between both
imaging techniques, solving the issues mentioned above.
