Now offering the latest in breast cancer screening technology: 3D Mammography
Available only at St. Agnes Hospital in Women's Imaging
3D mammography (tomosynthesis) is clinically proven to significantly increase the detection of breast cancers, while simultaneously decreasing the number of women asked to return for additional testing.
The limitation of digital mammography is that it creates a 2-dimensional picture of the breast, which is 3-dimensional. Glandular breast tissue located at different heights within the breast overlaps on 2D mammograms.
This overlapping tissue can hide breast cancers and may make normal tissue appear abnormal, leading to additional imaging. 3D mammography is an advanced technology in the fight against breast cancer that allows physicians to examine breast tissue one layer at a time. The imaging system uses high-powered computing to convert digital breast images into a stack of thin layers or “slices,” minimizing the negative effects of overlapping breast tissue and improving cancer detection.
Who can have a 3D mammography exam?
A 3D mammography exam is approved for all women who would undergo a standard mammogram. Multiple clinical studies show that all women, regardless of breast type or density, benefit from a 3D mammography exam.
What should I expect during your exam?
A 3D mammography exam is very similar to having a conventional 2D mammogram. Like a 2D mammogram, the technologist will position you, compress your breast and take images from different angles. There’s no additional compression required with the 3D mammography exam, and it only takes a few seconds longer for each view. The technologist will view the images of your breasts at the computer workstation to ensure quality images have been captured for review. A radiologist will then examine the images and report results to either your healthcare provider or directly to you.
Why choose a 3D mammography exam?
A 3D mammography exam detects 41 percent more invasive breast cancers and reduces false positives by up to 40 percent. This means one simple thing: more accuracy. The 3D mammography exam allows physicians to see masses and distortions associated with cancers significantly more clearly than conventional 2D mammography. Instead of viewing all of the complexities of your breast tissue in a flat image, as with conventional 2D mammography, fine details are more visible and no longer hidden by the tissue above or below.
