TruRadDose®
Volpara TruRadDose® analyzes the radiation dose delivered to patients based on their breast density instead of the dose estimated by the equipment manufacturer.
Mean glandular dose (MGD)
Radiation dose in mammography is low, but the breast is a relatively radio-sensitive organ and when millions of healthy women are being screened annually, it is important to ensure that the dose remains as low as reasonably possible while preserving diagnostic/screening image quality.
Mammography system manufacturers provide an MGD estimate for each image. However, several different algorithms exist for estimating MGD, and different ones have been chosen by each manufacturer.
One of the key inputs to those algorithms is breast density and most use age and compressed breast thickness to infer breast density.
Volpara TruRadDose® achieves a patient-based result using the globally accepted and validated Dance model of dose estimation, and the volumetric breast density results for each digital breast tomosynthesis or 2D mammogram image.

Comparison of a personalized breast dosimetry method with standard dosimetry protocols
“In this study we compared three diferent methods of estimating glandularities according to Wu, Dance and Volpara with respect to resulting AGDs .. As the Volpara method provides an analysis of the individual breast tissue, while the Wu and the Dance methods use look up tables and custom parameter sets, the Volpara method might be more appropriate if individual ADG values are sought.”
