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 - Pressure-standardised mammography does not affect visibility, contrast and sharpness of stable lesions.
Four experienced radiologists scored visibility, contrast and sharpness for 188 stable lesions and structures that were visible in pairs of mammograms: those obtained with a pain-tolerance limited 18 decanewton target force compression protocol and those obtained with the Sigmascreening 10 kPa (75 mmHg) pressure-standardized compression protocol. The latter compressions were significantly milder but nonetheless the lesion visibility, contrast and sharpness were statistically not inferior.

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)
