Wir möchten die Mammographie immer weiter verbessern


Weltweit werden jährlich etwa 150 Millionen Mammographie-Untersuchungen durchgeführt. Um die beste Bildqualität mit der niedrigsten Strahlungsmenge zu erhalten, muss die Brust komprimiert werden.

Wir haben eine patentierte Technologie für ein problemlos reproduzierbares Verfahren ohne unnötige Unannehmlichkeiten entwickelt. Optimierte Brustuntersuchungsverfahren tragen zur Früherkennung von Krebs bei, was letztendlich Leben retten kann.

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.
