We are pleased to offer patients 3D Mammography, also
known as digital breast tomosynthesis (DBT)—
a breakthrough technology poised to revolutionize
how breast cancer is detected today.

WHAT IS 3D MAMMOGRAPHY/
DIGITAL BREAST TOMOSYNTHESIS (DBT)?
• Digital Breast Tomosynthesis (DBT) is a 3D imaging technology
that acquires a series of low-dose projection images of the
compressed breast at different angles.
• The system produces thin slices of the breast, allowing
radiologists to step through slices one-millimeter at a time.
• Unlike a traditional mammogram, the slices separate objects at
different heights in the breast, producing a 3-dimensional
image.
Reviewing breast tissue slice by slice
allows the radiologist to view breast tissue
in a way never before possible.
WHAT IS COMBO-MODE?
• A unique feature from Hologic that quickly acquires a
traditional digital mammogram and a 3D scan
in the same compression.
Combo-mode* = 2D + 3D Imaging
* A screening exam consists of a digital mammogram and breast tomosynthesis image set.
WHAT ARE THE BENEFITS OF COMBO-MODE?
Hologic’s clinical studies reviewed by the FDA, based on ROC
analysis, showed radiologists reading Selenia® Dimensions®
digital mammography (2D) plus digital breast tomosynthesis
(3D) as compared to 2D mammography alone demonstrated
superior clinical performance in specificity, the confidence to
rule out breast cancer without recalling the patient for further
study, and improved sensitivity, the proportion of
mammograms with cancer which were correctly diagnosed.*

Selenia Dimensions combo-mode to Hologic 2D FFDM
WHY 3D MAMMOGRAPHY/DBT?
• Tissue superimposition :
• hides pathologies in 2D
• mimics pathologies in 2D
HOW DOES 3D MAMMOGRAPHY WORK?
• X-ray tube moves in an arc across the
breast
• A series of low dose images are
acquired from different angles
• Total dose approximately the same as
one 2D digital mammogram
• Projection images are reconstructed
into 1 mm slices
