The relationship of breast density in mammography and magnetic resonance imaging in high-risk women and women with breast cancer

PurposeTo evaluate the relationship between mammographic breast density (MBD), background parenchymal enhancement (BPE), and fibroglandular tissue (FGT) in women with breast cancer (BC) and at high risk for developing BC.MethodsOur institutional database was queried for patients who underwent mammography and MRI.ResultsFour hundred three (85%) had BC and 72 (15%) were at high risk. MBD (P= .0005), BPE (P< .0001), and FGT (P= .02) were all higher in high-risk women compared to the BC group.ConclusionsHigher levels of MBD, BPE and FGT are seen in women at higher risk for developing BC when compared to women with BC.
