We are inspired to improve mammography


Worldwide, circa 150 million mammographic examinations are performed every year. To get the best image quality with the least amount of radiation, the breast needs to be compressed.

We developed a patented technology for a highly reproducible procedure without unnecessary discomfort. An optimized breast examination contributes to the early detection of cancer which ultimately can saves lives.

2017 - Mammographic compression in Asian women
This study showed that a force-standardized mammographic compression practice led to widely variable compression parameters in Asian women. Asian women, who generally have smaller breasts, are subject to force standardized protocols. These protocols have largely been optimized for Caucasian women and might not be suitable for them. The mean ± standard deviation compression pressure for all mammograms (n = 15818) was 17.77±10.51 kPa. A phantom study showed that reducing compression force in Asian women has a limited impact on image quality and mean glandular dose.
2017 - Is breast compression associated with breast cancer detection and other early performance measures in a population-based breast cancer screening program?
To investigate early performance measures in a population-based breast cancer screening program, this study extracted compression force information and calculated pressure from DICOM-images on 261,641 mammographic examinations from 93,444 subsequently screened women. Results indicate that high compression force and low compression pressure provided more favorable performance measures, compared with low compression force and high compression pressure.


Press release - Groundbreaking pressure based mammographic paddle at European Radiology Congress (ECR), Vienna
Amsterdam, March 1, 2017 – Sigmascreening, a Dutch medical device company focusing on the development of new innovative products in the area of digital mammography and breast cancer screening, will demonstrate its groundbreaking Sensitive Sigma Paddle at the upcoming European Radiology Congress (ECR) in Vienna, 1 – 5 March, EXPO Hall X1 – booth no. 22. The paddle is the first pressure based compression paddle in the market providing real-time and reproducible mammographic pressure information and will considerably reduce commonly experienced unnecessary pain for women during screening. This could lead to higher response to screening invitations.
Annual Symposium Breast Screening Belgium. February 4, 2017, Bruges, Belgium
During the annual symposium Breast Cancer Screening in Belgium Sigmascreening will give a presentation on pressure-based breast compression. In this lecture we go deeper into the question whether optimal compression leads to better image quality which leads to an improved detection of breast cancer?

2016 Oct - Pressure controlled compression of the breast in mammography
Recent results show that the performance of mammography, in terms of detect- ability of cancerous lesions can be affected by the compression pressure at which the examination is carried out. This article describes the rationale behind the development of a pressure-based compression system. (First published in DIEurope October 2016)
