Breast cancer is the most common cancer in women and the second leading cause of cancer death. Early detection is the key to successful treatment and that’s why several countries have implemented mammography screening programs. However, many tumors are not detected by common 2D mammography in screening examinations. The reason is often tissue overlap in 2D images that leads to anatomical noise.
To overcome the challenges of tissue overlap in two-dimensional mammography, Siemens is constantly working on further enhancing mammography capabilities. With tomosynthesis, several views of the breast are acquired from different viewing angles and slice images are reconstructed into a 3D volume set. With this method, physicians can look through single slices of each breast with less overlap. This makes it much easier to determine the size of a lesion and the characteristics of the surrounding tissue. Not only clinicians benefit from this new technology for women, this may mean that they have to undergo less repeat examinations and get an earlier diagnosis and consequently, improved treatment.
Siemens MAMMOMAT® Inspiration is a highly flexible mammography platform for screening, diagnostics, and stereotactic biopsy that is already established and approved. Its basic system architecture, including stand, generator, detector, and software, is already prepared for future 3D imaging with tomosynthesis**. Furthermore, it is the only system in industry upgradeable on-site to tomosynthesis.

The RMLO digital mammography view shows dense breast tissue with subtle distortion in the lower breast. The RMLO tomosynthesis slice shows a spiculated mass in the lower breast, much more evident than the corresponding mammogram. Courtesy of University Hospital of Malmö, Sweden
