In Canada, a 2014 article reported the installation of three Selenia Dimensions DBT units at Toronto's Princess Margaret Cancer Centre, with plans for further expansion.8 News items report that other breast tomosynthesis units have been installed at a British Columbia centre and at the Women's Breast Health Centre in Ottawa.50,51
In 2013, the FDA decided that a low-dose 3D digital mammography was accurate enough to be used by itself, without also using 2D technology. 2D digital images can be obtained from the 3D mammogram data without the need for a separate test.
Inventor of Digital Breast Tomosynthesis.
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.
Digital Breast Tomosynthesis (DBT) - ELS
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.

We are performing both standard digital mammography and 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.

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.
