3D Breast Tomosynthesis

Breast tomosynthesis, also called three-dimensional (3-D) breast imaging, is a mammography system where the x-ray tube moves in an arc over the breast during the exposure. It creates multiple images, or “slices,” through the breast. This allows our radiologists to see greater detail, which can allow for improved detection of cancer and fewer patients recalled for additional imaging.

An accuracy advantage with dense breasts

Breast tomosynthesis is of increased benefit to women with dense breast tissue. While dense breast tissue may look similar to cancer in a traditional 2D mammogram, the 3D mammogram shows fine details more clearly.

Breast tomosynthesis exams are available at the following Advanced Radiology locations

Breast tomosynthesis is conducted on the same mammography equipment as a traditional 2D screening mammography. Breast tissue is compressed to spread and even out the tissue for better, more accurate images. For most women, this sensation is only mildly uncomfortable, and it lasts for only a few seconds. The exam usually takes 20 to 30 minutes to complete.

Do not use deodorant, antiperspirant, talcum powder or lotion under your arms or on your breasts on the day of the exam. Otherwise, no preparation is required.
