First 3D X-ray Mammography Imaging System of the Breast
​ 
   The U.S. Food and Drug Administration today approved the Selenia Dimensions System, the first X-ray mammography device that provides three-dimensional (3-D) images of the breast for breast cancer screening and diagnosis.
A mammogram is a safe, low-dose X-ray of the breast that is the best tool for early detection of breast cancer. However, with the limitations of conventional two-dimensional (2-D) imaging, about 10 percent of women undergo additional testing after the initial screening exam for abnormalities that are later determined to be noncancerous.
The Selenia Dimensions System, an upgrade to Hologic’s existing FDA-approved 2-D system, can provide 2-D and 3-D X-ray images of the breasts. The 3-D images may help physicians more accurately detect and diagnose breast cancer.
As part of the approval process, the FDA reviewed results from two studies where board-certified radiologists were asked to review 2-D and 3-D images from more than 300 mammography exams.  In both studies, radiologists viewing both the 2-D and 3-D images obtained a 7 percent improvement in their ability to distinguish between cancerous and non-cancerous cases as compared to viewing 2-D images alone.
The Mammography Quality Standards Act requires that all health care professionals obtain eight hours of training prior to using new mammography technology on patients. The FDA also requires that the manufacturer provide each facility with a manual clearly defining the tests required for initial, periodic, and yearly quality control measures.
According to the NCI, There is a 98 percent survival rate when breast cancer is detected early and still localized to the breast.
