Volumetric Breast Density Software Improves the Accuracy in Calculation of Patient-Specific Mean Glandular Dose (MGD) in Breast Screening
Date:8/7/2013

achines. “Our initial results suggest that current dose estimations may underestimate the actual patient MGD significantly as they do not account for the specific breast tissue composition. Patient-specific dose estimates may give a better indication of the actual dose delivered, and therefore the risk to the patient.”

The second study, “Retrospective Determination of Personalized Mean Glandular Dose Coefficients for Conventional Mammography Using Heterogeneously-layered Breast Models,” by Mariela Porras-Chaverri (Dept of Medical Physics, University of Wisconsin-Madison), took the personalization one stage further by not only using the patient-specific volumetric breast density, but also considering how the tissue might be dispersed within the breast. “The glandular and adipose breast tissues are distributed heterogeneously within the breast. Depending on the individual distribution with respect to the beam entrance surface, the mean dose delivered to the glandular tissue may be higher or lower than estimated by the current methods. Our on-going study aims to provide a means to account for the heterogeneous distribution of the glandular tissue in estimates of mean glandular dose.”

Cleared by the FDA, HealthCanada, the TGA and CE-marked, Volpara is in use at sites across the globe helping radiologists assess breast density more objectively and helping them better consider who might benefit from additional screening. Volpara is a reliable tool which generates objective, automatic measurement of volumetric breast density and a FDA cleared BI-RADS breast density category. Volpara supports most of the major digital mammography systems, can be displayed on digital mammography and PACS workstations and be integrated into mammography reporting systems.
