Accurate Volumetric Assessment

Clinically Proven for Digital Mammography and Digital Breast Tomosynthesis

Experience the Benefits of Volpara®Density™ Software

  • Reproducible and objective results when compared to human assessment of breast composition.
  • Consistent across manufacturers, models, and imaging modes. Compatible with most digital mammography and tomosynthesis units.
  • Immediate identification of women who may benefit from supplemental screening.
  • The only volumetric breast density (VBD%) assessment validated with the Tyrer-Cuzick 8 risk model.


VolparaDensity software uses x-ray physics and machine learning to generate an accurate volumetric measure of breast composition. It provides a repeatable, consistent, and objective means of scoring breast density and produces a scorecard that displays key metrics.

"Radiologists can guestimate the percentage of breast tissue that is dense, but they are still using 2D information to assess a 3D phenomenon, and they cannot possibly be accurate in any absolute sense."
– Professor Dan Kopans, Radiology, v246, #2, Feb 2008

The Case for Automated Breast Density Assessment

  • 4–6 times greater risk1 for women with dense breasts to develop breast cancer when compared to women with fatty breasts.
  • 30% less sensitivity2 in mammographic cancer detection for women with dense breasts when compared to women with fatty breasts.
  • Visual density assessment is not always consistent,3 with 57% inter-reader agreement and 77% intra-reader agreement.

FDA Cleared

VolparaDensity is FDA cleared to provide both volumetric breast density measurements and a breast density category, shown to correlate to BI-RADS® 4th and 5th Edition density categories, from most digital mammography vendors. It is easy to implement clinically, and quickly helps increase consistency and compliance with state laws while improving productivity and workflow.

VolparaDensity is used every day at clinical sites worldwide and has been validated in many peer-reviewed clinical studies at prestigious institutions. VolparaDensity has been strongly associated with risk of interval cancers4,5,6 and risk of developing breast cancer.7,8,9
