Determinants of percentage and area measures of mammographic density.
Mammographic density is one of the strongest predictors of breast cancer risk. Typically expressed as a percentage of the breast area occupied by radiologically dense tissue on a mammogram, its full value may not be realized because of its negative association with body mass index. A simpler measure of mammographic density, independent of other breast cancer risk factors and equally predictive ...

متن کاملAgreement of Mammographic Measures of Volumetric Breast Density to MRI
BACKGROUND Clinical scores of mammographic breast density are highly subjective. Automated technologies for mammography exist to quantify breast density objectively, but the technique that most accurately measures the quantity of breast fibroglandular tissue is not known. PURPOSE To compare the agreement of three automated mammographic techniques for measuring volumetric breast density with a...
متن کاملEnhancement of mammographic density measures in breast cancer risk prediction.
BACKGROUND Mammographic density is a strong risk factor for breast cancer. METHODS We present a novel approach to enhance area density measures that takes advantage of the relative density of the pectoral muscle that appears in lateral mammographic views. We hypothesized that the grey scale of film mammograms is normalized to volume breast density but not pectoral density and thus pectoral de...
متن کاملPlasma levels of enterolactone and percentage mammographic density among postmenopausal women.
AIMS Certain phytoestrogens, such as lignans, may protect against developing breast cancer. Enterolactone is a lignan metabolite produced by the intestinal flora from dietary precursors such as whole grains, vegetables, and fruits. Enterolactone has been shown to have weak estrogenic and antiestrogenic properties. We decided to examine the association between plasma levels of enterolactone and ...
