The relation between Background Parenchymal Enhancement [BPE] and breast parenchymal density with breast cancer risk factors in MR mammography

Abstract

Breast MRI is one of the most important diagnostic tools in the field of breast carcinoma. The value of this diagnostic modality is in the high sensitivity and diagnostic power of lesions that are not detectable even in examination and mammography. Measurement of breast density (FGT), underlying intensification of the breast parenchyma (BPE) in MR mammography and then examining the relationship between the findings and the identified risk factors. Methods and Materials: In this cross-sectional study, breast density was measured among all women over 40 years of age in MR mammography and underlying breast parenchyma (BPE) in patients referred to the radiology clinic of Imam Reza Hospital. It was evaluated with other risk factors for breast cancer. 105 patients were randomly selected and their breast density and underlying intensification of the breast parenchyma (BPE) were measured. The amount of BPE was classified into 4 categories: Minimal, Mild, Moderate and Marked, according to the amount of contrast material in the underlying breast tissue. Then, according to the list of breast cancer risk factors, their relationship with breast cancer risk factors is determined. Data will be analyzed in SPSS software.

Results: Our findings in this study showed that there is a significant relationship between the degree of underlying parenchymal exacerbation and the use of contraceptive pills in women (p <0.05), so that the highest number of women taking birth control pills (85.7%) have Moderate-type underlying parenchymal exacerbation, and the largest number of women who did not use birth control pills (46.2%) had Moderate-type underlying parenchymal exacerbation and 33% had Mild-based underlying parenchymal exacerbation.
