Despite of the development of a new volumetric breast
density (Quantra) analysis tool, still it is not known
how accurate the acquired density results are. This
study aimed to compare the results of density
measurement using Quantra and 3D MRI in the same women.
56 women were studied. The MR density analysis was based
on a novel semi-automatic method. Overall, moderate
correlation (r=0.55 for the right breast and r=0.65 for
the left breast) between the two modalities was noted.
Huge measurement variations in the two modalities were
noted in a few women, unexplained by the breast density
or breast morphology.
