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.
2016 - Force balancing in mammographic compression
Skin stretching is often regarded as an inevitable side-effect of mammographic breast compression, but this study shows that much unnecessary stretching can be avoided by adequately adjusting the position of the X-ray image receptor to the height of the patient...


Sigmascreening will be sharing at the Congrès SIFEM exciting feedback from their new installation
In the context of a larger research study on the influence of the use of the Sensitive Sigma™ Paddle on compression practices, patient satisfaction, dose and image quality at the Centre Réne Huguenin- Institut Curie: the preliminary results showed a significant reduction in breast thickness while 90% of the patients expressed superior or similar comfort levels compared to their previous mammography examination.The Sensitive Sigma™ Paddle has also been extremely positively received by the medical staff (radiologists and radiographers).
Norwegian study confirms the potential health benefits of pressure based breast compression
Amsterdam, The Netherlands, May 22, 2017 – Sigmascreening, a Dutch MedTech developer and world leader in the field of pressure based digital mammography and breast cancer screening, announces that a large independent Norwegian study1 further confirms Sigma’s hypothesis that pressure has a clear relation with the most optimal results in mammography. The study confirms the importance of pressure in accordance with Sigmascreening’s concept of the Sensitive Sigma™ Paddle, which applies pressure guidance during mammography.

"Most women don't like breast screening due to pain and refrain from participation. The Dutch company Sigmascreening developed a technology that greatly reduced this inconvenience. A special collateral profit: with this method, more tumors can be detected."
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)
