3D Mammography (Tomosynthesis)

More detail. More accuracy. More peace of mind.

Early detection is the best defense you have against breast cancer. The UConn Health Center offers the latest FDA approved technology that creates 3D breast images that help doctors detect breast cancer earlier than previously possible.

With 3D mammography or tomosynthesis, doctors can:

• Detect abnormalities that aren’t detected by traditional mammograms
• Deliver more detail and accuracy providing women with more peace of mind

What Is 3D Mammography (Tomosynthesis)?

Traditional mammography is two-dimensional (2D) or flat. Breast tissue is made up of pockets of dense tissue surrounded by fat. When it’s x-rayed, the images can be hazy, and this makes it hard to see early signs of cancer.

3D mammography converts digital breast images into a stack of very thin layers or “slices”—building what is essentially a 3-dimensional mammogram. This allows radiologists to look at your breast tissue in far greater detail than a traditional mammogram.

What You Should Expect During Your Exam

A tomosynthesis exam is very similar to a traditional mammogram. At the UConn Health Center, you will receive a 2D mammogram, as well as a 3D mammogram, which gives physicians more data.

During the tomosynthesis portion of the exam, your breast will be under compression while the x-ray arm of the mammography machine makes a quick arc over the breast, taking a series of breast images at a number of angles.

The whole procedure should take approximately the same time as that of a traditional mammogram. The technologist sends your breast images electronically to the radiologist, who studies them and reports results to either your physician or directly to you.

Who Should Get 3D Mammography?

• Women over 40 who have dense breast tissue
• Women who are at high risk for breast cancer

How Much Radiation Will I Be Exposed To?

The amount of radiation exposure is equivalent to screen film mammography.
