Association of breast arterial calcifications detected by mammography and coronary artery calcifications quantified by multislice CT in a population of post-menopausal women.

Abstract

The study demonstrated that the presence of BAC is strongly correlated with the amount of coronary calcium detected by MSCT and therefore with the extent of coronary atherosclerosis. Moreover, there is a linear correlation between BAC severity and coronary calcium content, each incremental increase in BAC severity being associated with an average increase in coronary calcium content. Therefore, the presence and severity of BAC may provide indirect qualitative and quantitative information on the calcium present in the coronaries. As mammography is increasingly used as a screening test for breast carcinoma, breast arterial calcifications may represent an important sign with epidemiological and clinical significance for primary prevention.
