In this study we measured the background tissue enhancement from the segmented fibroglandular tissue. We found a weak correlation between the percent density and the BPE, suggesting that although they were associated but not highly correlated. Women of younger age tended to have higher BPE than older women. Also, younger women were more likely to show decreased BPE after chemotherapy. The effect of BPE reduction in younger women was most likely due to the ovarian ablation induced by chemotherapeutic agents, thus it may be used as a risk predictor for development of contralateral breast cancer.
