DBT should be used as an adjunct to conventional 2D breast imaging, not as a replacement, according to the FDA. With that, many breast imagers believe in the technology combination, one even predicting it could become an industry standard. “We’re finding more cancers with tomosynthesis, and we have a reduced recall rate,” says Jaime Geisel, MD, an assistant professor of diagnostic radiology at the Yale University School of Medicine. “If we can reduce false-positives with mammography and tomosynthesis, then maybe we have a better screening test. The new gold standard could be 2D with 3D.”

Geisel was the principal investigator among a team of researchers at the university’s Smilow Cancer Hospital in New Haven, Connecticut, which recently announced results of a study on adding DBT to screening mammography. The retrospective review of 14,684 women who received screening mammograms at Yale from August 2011 through July 2012 showed an 11% increase in the rate of breast cancer detection among women who underwent both 2D and 3D screening. Geisel adds that tomosynthesis appeared to be more valuable in women with dense breast tissue, as 54% of the women whose cancer was found with tomosynthesis had dense breast tissue.

Tomosynthesis/3D Mammography - Jefferson Radiology

Clinical studies reviewed by the FDA showed radiologists reading digital mammography (2D) plus breast tomosynthesis (3D) as compared to 2D mammography alone demonstrated superior clinical performance in specificity, fewer recalls for overlapping normal tissue on screening mammograms, and improved sensitivity, the proportion of mammograms with cancer which was correctly diagnosed.

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.

Tomosynthesis is a revolutionary technology that gives radiologists the ability to identify and characterize individual breast structures without the appearance of overlapping tissue. During a tomosynthesis scan, multiple, low-dose images of the breast are acquired at different angles. These images are then used to produce a series of one-millimeter thick slices that can be viewed as a three dimensional reconstruction of the breast. Tomosynthesis combines the advantages of digital mammography with a 3D perspective.

Digital Breast Tomosynthesis (3D Mammogram)

We are performing both standard digital mammography and 3D tomosynthesis at the same time. Adding tomosynthesis does involve a minimal amount of additional radiation, compared with a standard mammogram; however, no risk from an amount of radiation this small has ever been proven. The radiation dose for the combined 2D and 3D exam at SJRA is under the FDA regulated limit for mammography. The FDA thoroughly considered the radiation issue before approving tomosynthesis for use in screening and diagnostic exams and approved this new technology because the benefit of the additional information available to the radiologist outweighs the potential risk.
