3D Mammography

Genius™ 3D MAMMOGRAPHY™ exams, developed by Hologic, Inc., use advanced breast tomosynthesis
technology to increase detecting breast cancers, while decreasing callback rates.

In conventional 2D mammography, overlapping tissue is a leading reason why small breast cancers may be
missed and normal tissue appear abnormal. A 3D tomosynthesis exam uses imaging that reduces tissue
overlap by taking multiple images. A computer then converts the images into a stack of thin layers, allowing
the radiologist to review the breast tissue one layer at a time. The 3D exam requires no additional
compression and takes just a few seconds longer than a conventional 2D breast cancer screening exam.

The largest study to date on breast cancer screening using the Genius exam appeared in the June 25, 2014,
issue of JAMA. Findings include:
• 41% increase in detecting invasive breast cancers
• 29% increase in detecting all breast cancers
• 15% decrease in contacting women for additional imaging

3D tomosynthesis is a major advance for women with dense breast tissue. It has a better cancer detection
rate than routine digital mammography and enhances the patient’s experience of breast cancer screening by
decreasing callbacks for more tests. The system allows radiologists to more effectively pinpoint the size,
shape and location of abnormalities, leading to better detection and greater peace of mind for patients.
3D tomosynthesis is approved by the FDA and covered by Medicare and some insurance. A $75 upfront fee
is charged for those whose insurance does not cover the 3D exam. This exam is recommended for women of
all ages and breast density.
