Breast Tomosynthesis

Breast tomosynthesis creates thin image layers of the breast to help the radiologist examine overlapping tissue.

It is often described as three-dimensional mammography because the image set can be reviewed layer by layer. Compression is used to hold the breast in position while images are acquired.

Tomosynthesis may be used during a screening examination or when a clinician needs more detail after an earlier breast image. The radiologist reviews the image layers along with your clinical information and may compare them with previous images when available.

The appointment is similar to a mammogram: a technologist positions each breast, applies compression, and takes the required views.

Tomosynthesis does not diagnose every breast condition, and an image finding may need further assessment before its cause is known. Dense or overlapping tissue, motion during imaging, and the nature of a finding can affect how clearly an area is seen.

A normal imaging result does not replace assessment of a new breast change. Report a persistent lump, skin change, nipple change, or unusual discharge to a clinician.

Standard mammography, breast ultrasound, and breast MRI can each be useful in different situations. The chosen examination depends on the concern, your symptoms, earlier images, and whether more information is needed after an initial result.

A result may say that no further imaging is needed, or it may recommend additional views, ultrasound, follow-up imaging, or a discussion about biopsy. A request for more imaging is a way to clarify an area; it does not by itself establish a cancer diagnosis.

Compression can be uncomfortable for a short time, but it helps reduce movement and spread the tissue for imaging. Tell the technologist if you are pregnant, might be pregnant, have breast implants, have had breast surgery, or have a painful area so they can adapt positioning and record relevant information.
