T1 - Digital breast tomosynthesis

Purpose: To investigate the dependence of microcalcification cluster detectability on tomographic scan angle, angular increment, and number of projection views acquired at digital breast tomosynthesis (DBT).

Breast cancer screening using tomosynthesis in combination with digital mammography.


As Destounis notes, one reality of DBT is the current lack of reimbursement for this modality, and purchasing systems can be costly. If a facility is just planning a conversion to digital mammography, this could be a viable option because the Hologic system does both, she says. However, for hospitals and imaging centers that have already made the switch, it could be cost-prohibitive to replace relatively new digital mammography equipment right away.

Conant has received grants from the National Institutes of Health to compare standard surgical biopsy with digital mammography and stereotactic core breast biopsy.

Radiologists at the Rochester facility are also looking at ways to utilize tomosynthesis in cases where patients’ mammograms showed overlap of tissue, recalling women to obtain an “extra view” of questionable breast tissue. Destounis says in some instances, this second scan, using DBT, enabled clinicians to rule out a patient’s need for biopsy.

Traditional two-dimensional (2D) mammography captures two static images of the breast. One particular shortcoming of 2D technology is the overlapping of breast images that can decrease accuracy of interpretation. With digital breast tomosynthesis (DBT), an X-ray beam sweeps in an arc of 15 to 50 degrees (depending on the manufacturer) across the breast, and an electronic detector digitally captures between nine and 25 X-ray projection images.1-6 These images are generally captured in two views: craniocaudal (head-to-toe direction) and mediolateral oblique (angled side-view).2,3,5 The data from these projections are used in computer algorithms to reconstruct a series of parallel thin "slices" (tomographic images) corresponding to 0.5 mm to 1 mm intervals through the breast. The slices create a three-dimensional (3D) volume of data that represents the breast's tissue structures.

Conant, a pioneer in the development of digital mammography, is a leader in research on the use and benefits of early mammography screening and on the role of multimodality breast imaging.


A number of studies of DBT for breast screening were identified. The seven largest studies (each enrolling more than 10,000 women)28,31,33-38 were selected for detailed review in this report (Table 1). All studies were based on established breast screening programs using Hologic Selenia Dimensions technology for 3D screening, with six studies conducted in the US28,31,33-35,38 and the seventh in Norway.36 The Norwegian study was prospective (women received both types of imaging and served as their own controls), while the American studies were retrospective (four were before-and-after studies of outcomes once the new technology was installed33-35,38 and two enrolled groups of women who received the older and newer technologies at different sites over the same time period).28,31 The Norwegian study involved double reading with arbitration: all images in the study were interpreted by two independent radiologists who had to reach a consensus for the need for recall before a woman was asked to return for more imaging.36 Study sizes ranged from approximately 13,000 to approximately 450,000 women. Of the six studies that reported sources of research support and conflicts of interest, three noted ties to Hologic.35,36,38 Additional study details are presented in Appendix A.

Destounis presented research findings at the American Roentgen Ray Society’s annual meeting earlier this year showing that DBT is comparable to or better than conventional digital breast mammography at identifying microcalcifications in up to 95% of cases. Elizabeth Wende was one of the sites that collected data while using Hologic’s Dimensions system.
