Advantages of Digital Mammography with 3D Tomosynthesis

Hologic announced in February that it received FDA approval for Dimensions 3D. Clinical trials using the system showed measurable improvement in clinical performance over conventional mammography as well as gains in specificity, improved lesion and margin visibility, and the ability to accurately localize structures in the breast.

Benefits of Breast Tomosynthesis (3D Mammography) include:

Film, 2D digital, and 3D mammography involve the same amount of physical discomfort.

“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.

Efforts are under way to have the FDA approve 3D mammography without the need for a 2D mammogram.

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.

3D or not 3D? That is the question many radiologists are asking as they consider the most effective use for digital breast tomosynthesis (DBT).

New 3-D mammograms have benefits, risks - USA TODAY

Because 3D mammography allows the radiologist to examine breast tissue layer by layer, it is easier to discern finer details in dense breasts that may occasionally be masked in a traditional 2D mammogram. Our technologists will let you know if your breast tissue is dense enough to benefit from 3D mammography.

2D screening mammograms are free for patients covered by healthcare insurance under the Affordable Care Act. Some insurers will not cover 3D mammograms, and others charge women a surcharge. However, Medicare began covering 3D mammography in 2015 and some states are beginning to mandate coverage.

3-D Tomosynthesis Mammography - BayCare

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.
