Percée innovante en mammographie issue recherches scientifiques approfondies.

Nous sommes résolus à améliorer la mammographie.


Dans le monde, environ 150 millions de mammographies sont effectués chaque année. La compression du sein est nécessaire en mammographie pour optimiser la qualité d'image et réduire au minimum la dose de rayonnement absorbée. Cependant, la compression mécanique du sein durant la mammographie provoque souvent inconfort et douleur et dissuade ainsi certaines femmes de la mammographie de dépistage.

Notre technologie brevetée issue recherches scientifiques approfondies permet une compression hautement reproductible sans inconfort inutile. Un examen optimisé contribue à la détection précoce de possible cancer et permet ainsi de sauver des vies.

2018 - Clinical validation of a pressure-standardized compression mammography system
In a retrospective study, mammograms acquired using a pressure-standardized compression protocol were intra-individually compared with the prior mammograms using a force-standardized compression. Pressure-standardized compression provided a mean breast pressure that was almost independent on breast size. Additionally, the mean pressure was significantly lower and the number of over-compressions (>20 kPa) reduced significantly for the pressure-standardized compared to the force-standardized protocol, suggesting a reduction of patient discomfort and pain. 
2017 - Influence of breast compression pressure on the performance of population-based mammography screening
In a retrospective study of 57,179 women participating in the Dutch population based screening program with a total of 132,776 digital mammographic examinations, digital image analysis was used to determine the pressure exercised during image acquisition. Volpara software was used for the analysis. The data were subdivided into quintiles of pressure and the number of screen-detected cancers, interval cancers, false positives, and true negatives were determined for each of the 5 groups. Generalized estimating equations (GEE) were used to account for confounders; pair-wise testing for significant differences was performed. In conclusion; results suggest that if too much pressure is applied during mammography this may reduce sensitivity. In contrast, if pressure is low this may decrease specificity.  A similar study on data of the Norwegian population based screening was recently published by N. Moshina et al in Breast Cancer Res Tr  (2017 Jun;163(3):605-613),  with comparable results.
