Abstract
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. FFDM 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 large number of false positive results. The results of our study showed that contrast enhanced spectral mammography, Tomosynthesis and breast ultrasound have superior diagnostic accuracy than mammography in dense breast parenchyma. Contrast enhanced spectral mammography has a significant higher specificity while breast ultrasound has a significant higher sensitivity compared to other imaging modalities. Breast tomosynthesis showed higher senstivity and specificity than mammography
