3-D Mammography, also known as tomosynthesis, use X-rays to create 3-dimensional images. The procedure is the same from the patient?s point-of-view, although it will take a few seconds longer. In 2-D mammograms, two projection conventional images from above and side are taken. In digital tomosynthesis, multiple images are taken from multiple angles as the X-ray tube moves along an arc around the breast before releasing the compression following the 2-D image. This information is linked to a computer and the 3-D images are displayed at 1 mm slice thickness throughout the breast.
3-D mammography is particularly useful for women who have dense breast tissue. On a conventional 2-D mammogram, dense breast tissue appears white and sometimes can hide masses, such as cancer. 3-D mammography overcomes this obstacle.
With 3-D mammography, radiologists can examine breast tissue layer by layer. Fine details are more visible and are no longer hidden by tissue above or below. Radiologists are able to more clearly differentiate overlapping breast tissue from suspicious areas, significantly reducing the need for screening callbacks.
The 3-D system offers the lowest possible radiation from its advanced detector technology.
Talk to your provider to see if you meet the criteria for 3-D mammography. 3-D mammography is available to all patients. Check with your insurance carrier to confirm your 3-D mammography coverage.
