[Value of CAD systems].
OBJECTIVE
Early detection of breast cancer enables for the reduction of mortality. The purpose of this article is to describe commercially available systems for computer-aided diagnosis (CAD) for mammograms and to analyze their diagnostic potential and utility.


METHODS
Up to now, there are three CAD-systems available, the Image Checker M 1000 (R2-Technology, USA), the Second Look-system (CADx Medical Systems) and the Mammex TR (Scanis Inc., USA). Most of the present studies are done with the R2-system. The mammographies have been digitalized secondarily. Different algorithms recognized microcalcifications and masses. The connection between full field digital mammography systems and DICOM-networks is possible.


RESULTS
In retrospective and one large prospective study with 12.860 patients it could be shown that sensitivity of the investigator with CAD could be improved up to 19%, microcalcifications are yielded with CAD in 100%, masses in up to 80%.


CONCLUSIONS
Double-reading with CAD-systems can increase early breast cancer detection effectively. Regarding the development of full field digital mammography we are looking forward to further innovations.
