In this study we aimed to correlate percent breast
density (PD) and background parenchymal enhancement (BPE)
in the contralateral normal breast (CNB) of patients
diagnosed with breast cancer. Breast MR images of the
CNB of 117 patients were studied. The quantification of
the fibroglandular tissue volume (FV) was based on a
computer-assisted algorithm. The mean BPE and the hot
spot enhancement were correlated with age, and also with
FV and PD. Our study showed that BPE, measured by the
averaged enhancement of the whole FV or by hot spot, did
not correlate well with quantitative measurement of PD
and FV.
