Dense breast tissue: What it means to have dense breasts BPE refers to the normal enhancement of the breast fibroglandular tissue. First, using our . However, it is not related to significant differences in positive biopsy rate, cancer yield, sensitivity, or specificity of MRI. Roughly one-half of women have dense breasts. The degree of normal fibroglandular tissue that enhances on breast MRI, known as background parenchymal enhancement (BPE), was initially described as an incidental finding that could affect interpretation performance. Thank. In type 2 there is a scattering of fibroglandular tissues, ranging from 25% to 50% of the breast. One of the strongest known risk factors of breast cancer, breast density [i.e., the "amount" of fibroglandular tissue (FGT)], is assessed using mammography and has been successfully incorporated into models of breast cancer risk [1, 2].Breast density can also be estimated by assessing FGT on breast magnetic resonance imaging (MRI) [].After administration of the contrast agent during a . Treatment with 6-12 months of anastrozoles or letrozole was associated with decreases in BPE, which occurred in a greater proportion of women than decreases in FGT, and similar results were seen when women also undergoing chemotherapy were excluded. MRI background parenchymal enhancement, breast density and breast 2.2.2 Background Parenchymal Enhancement (BPE) BPE is the normal enhancement of fibroglandular tissue and should be assessed on the first set of post-contrast images, which are obtained 90 seconds after contrast administration. Fibroglandular tissue proportion was visually assessed using precontrast T1-weighted images and was graded according to the BI-RADS criteria into 4 categories: (1) almost entirely fatty (<25% FGT), (2) scattered FGT (25%-50% FGT), (3) heterogeneously FGT (50%-75% FGT), and (4) extreme FGT (>76% FGT). Normal fibroglandular breast tissue will demonstrate enhancement, but this enhancement is rather easily recognized as it is visible in the lateral part of both breasts.

Heterogeneously Dense Breasts with Lots of Fibroglandular Tissue Breast tissue is composed of milk glands, milk ducts and supportive tissue (dense breast tissue), and fatty tissue (nondense breast tissue). 4 However, mammography suffers from tissue superimposition . It is described as the volume and the intensity of enhancement and is advised to be categorized on the basis of volume but not on the basis of percentages divided into quartiles. Fibroglandular tissue refers to areas in the breast containing milk glands and milk ducts. BPE does not necessarily correlate with the amount of fibroglandular tissue. The more complex (and generally denser) the parenchyma, the higher the risk of subsequent breast cancer. BPE is thought to be under the effect of blood flow in dense breast tissue and may represent breast activity ( 3 ).
