In this article, we briefly review the background to the increasing interest in the measurement of breast density and point out limitations of the current methods of
quantitative measurement of breast density using two dimensional mammography.
We describe the emergence of various three dimensional imaging methods for the quantification of breast density and present the results of the use of low dose chest computed tomography (LDCT) to measure breast density. LDCT is increasingly being used, e.g. in lung cancer screening, so the use of an already exisiting imaging data set may represent an efficient opportunity to provide quantitative 3D breast density determinations.
