Aims and objectives
Breast density is normally evaluated with mammography using the BI-RADS lexicon,
which is a subjective semi-quantitative classification [1].
Two main points regarding mammographic density should be taken into account: the so called “masking effect”,
i.e.
increased breast density reduces sensitivity in cancer detection,
and the role of breast density as an independent risk factor for breast cancer [2][3][4].
For these reasons in the latest years there is a growing interest not only for breast imaging not only in terms of identification of breast cancer but also for the evaluation of normal breast characteristics,
with the development of new methods for the evaluation of breast density [5][6][7][8].
The aim of this study was to investigate whether a qualitative evaluation of mammographic breast density (MBD) correlates with the MRI breast density (MRBD),
obtained through a volumetric quantitative measurement performed on breast MRI using Dixon sequences.
Moreover we investigated the correlation between the qualitative (BPEql) and quantitative evaluation of background enhancement (BPEqn) on breast MRI and between the density (MD) and the background enhancement (BPE) obtained both at the qualitative and quantitative evaluation.
