“The combination of measurable improvements in accuracy and detection and improved sensitivity makes the Dimensions 3D system a superior system versus conventional digital mammography systems,” Hologic President and CEO Rob Cascella said via a press release. “Our technology takes advantage of all the benefits of digital mammography and quite simply makes it better with the combination of fast, high-quality 3D breast imaging. We believe tomosynthesis has the potential to change how screening and diagnostic mammography is performed and over time will prove invaluable to the earliest possible detection of breast cancer and in the reduction of unnecessary diagnostic interventions.”
Digital tomosynthesis creates a 3D picture of the breast using X-rays
According to Hologic, DBT produces 3D images intended to reveal the inner architecture of the breast without the distortion that can result from tissue shadowing or density. Tomosynthesis images are acquired with the breast held briefly in compression, just as it would be during a conventional mammogram. The exam consists of a tomosynthesis image in combination with a 2D image. This “combo-mode” method allows for both images to be taken during the same compression. In addition, the company says combining the two modalities takes into consideration radiologists’ existing familiarity viewing 2D images.

3D Mammography, clinically known as, Digital Breast Tomosynthesis (DBT), obtains multiple images of the breast and reconstructs them to create a 3D image of the breast rather than a single image. This technology improves the detection of small cancers and has been shown to reduce the number of patients recalled for more imaging due to false positives. This is used for screening patients, and can also be utilized as an additional screening tool if a patient’s 2-D mammogram shows dense breast tissue.
Mammography/3D Mammography (Tomosynthesis):
The results of the studies showed that the combination of 3D and 2D was more accurate than 2D digital or film mammograms, although the difference in accuracy was tiny for each patient.,,,,, Just as importantly, women who undergo screening with 3D+2D mammography are less likely to be called back for more testing due to a suspicious finding that turns out not to be cancer. This means fewer false scares.
