Volpara®Enterprise™ DDP Software—Density, Dose, and Pressure Assessment

The Volpara clinical functions provide quick, automated assessment of every mammography and tomosynthesis exam. The output of VolparaEnterprise DDP is the Volpara Scorecard, which contains patient information, breast density category (a, b, c, or d), Volpara Density Grade™ scale, individual breast metrics, and average dose and pressure.

  • VolparaDensity provides an objective measure of breast composition that allows you to guide patients through personalized supplemental screening programs that build new revenue streams 
  • VolparaDose analyzes patients' personalized x-ray dose, based on their own breast density rather than the equipment manufacturer's estimate
  • VolparaPressure measures the pressure applied to the breast, providing a clearer understanding of the patient experience and the effectiveness of each mammogram

Understand More About Breast Density

The breast density components of the Volpara Scorecard work together to give you an automated and repeatable platform for triaging women to supplemental imaging. Extensive clinical studies on the Volpara Density Grade (a BI-RADS®-like breast composition value) and recent reports on the Volumetric Breast Density percentage (VBD%) have shown that increasing Volpara density values correspond to reduced mammography sensitivity.1,2 The Volpara Density Grade and VBD% have also both been demonstrated to relate to increased risk of breast cancer.3,4 Thus, Volpara can be used to provide supplementary screening to women who need it most:

  • Screening ultrasound. The Volpara Density Grade provides an objective means of identifying those women with high breast density who may benefit. Ultrasound is effective for finding additional cancers in women with high density and negative mammography.5
  • Breast MRI. The VBD% provides a more granular assessment of density than is used in the Tyrer-Cuzick v8 Breast Cancer Risk Evaluation Tool, one of the gateways to breast MRI imaging of high-risk patients.6

Best of all, VBD% has been shown to strongly and linearly correlate to the sensitivity of mammography, making you aware of the performance of mammography as a test in each patient.

Understand More About Patient Dose

The Volpara Scorecard includes average dose information about the patient:

  • VolparaDose is computed based on the patient's breast composition, rather than manufacturer dose, which is based on phantom measurements
  • VolparaDose analyzes each woman’s mammogram differently, because not all women with a 4-cm breast have the same breast density7 or receive the same radiation exposure

Understand More About Compression Pressure

Studies have shown that some women don't return to mammography because of discomfort, or fear of discomfort.8

  • VolparaPressure reveals the pressure applied to the breast by the force of compression that is distributed across each woman's breast tissue
  • VolparaPressure informs your practice about a key aspect of each woman’s experience in your practice,9 how she has been treated, which is key to encouraging her to return
  • VolparaPressure also guides you towards optimal clinical performance, as recent studies have shown that too much or too little compression pressure can adversely affect the clinical performance of the exam10

Quality Begins with VolparaEnterprise Clinical Applications

VolparaEnterprise DDP bundles three key clinical functions that can keep your attention focused on the patient. All Volpara clinical functions stem from the breast density and other metrics that are measured from a woman’s mammogram. The clinical applications use repeatable and objective measures to avoid reliance on inter- and intra-reader variability,9 or, in the case of VolparaDose, poor assumptions.11
