Volumetric breast density techniques compare well with MRI results, according to a study of Matakina International's VolparaDensity software published in PLOS One (December 4, 2013) and presented at RSNA 2013 in Chicago.
Researchers at the University of California, San Francisco (UCSF) compared several automated methods of assessing volumetric breast density from digital screening mammograms and evaluated their agreement with a quantitative volumetric MRI-based technique. The results demonstrated that VolparaDensity had the highest correlation with MRI for fibroglandular volume, outperforming the other commercial methods.
VolparaDensity is used to assess density from both digital mammography and tomosynthesis images and help evaluate who might benefit from additional screening, Matakina said. Highly correlated to breast MR assessments, VolparaDensity automatically generates an objective measurement of volumetric breast density and a BI-RADS breast density category. To date, more than 2 million women have had their volumetric breast density analyzed using VolparaDensity, the company said.
