Role of Tomosynthesis with correlation to 2D Mammography in characterization of breast lesions in dense breast

Abstract

Breast cancer remains one of the leading causes of death in women over the age of 40 years. Women with dense breast are doubly disadvantaged as they are both at higher risk of developing breast cancer and at greater risk that cancer will not be detected because of masking of the radiological signs of cancer by increased density. Mammography is the best-studied breast cancer screening modality and the only recommended imaging tool for screening the general population of women. Inspite of this, mammography is accused of having a low sensitivity because the overlapping breast tissue may hide an abnormality and this increases the number of false negative results. On the other hand it is accused of having a low specificity because the overlapping tissues may give the impression of a false abnormality which is responsible for a large number of false positive results. In this study, we compare the efficacy of digital breast Tomosynthesis (BDT) to digital Mammography (DM) in diagnosis of different breast lesions in dense breast.
