Breast Tomosynthesis Also Known as 3D Mammography

What is Mammography?

Mammography is a specific type of imaging that uses a low-dose x-ray system to examine breasts. A mammography exam, called a mammogram, is used to aid in the early detection and diagnosis of breast diseases in women. 

Breast Tomosynthesis Also Known as 3D Mammography

The American Cancer Society recommends annual mammograms for women starting at age 40. 3D mammography is approved for all women who would be undergoing a standard mammogram, for both screening and diagnostic exams.

3D mammography is much like your annual mammogram but more accurate in earlier breast cancer detection. 3D works by capturing multiple slices (images) of your breast from several angles. Then, a computer produces a 3D image of your breast tissue in one millimeter slices. Our radiologist can review the data, one slice at a time, like turning pages in a book, making it easier for them to see if there is anything to be concerned about.

A 3D exam detects 41% more invasive breast cancers and reduces false positives by up to 40%. This means one simple thing: more accuracy.

The 3D exam allows doctors to see masses and distortions associated with cancers significantly more clearly than conventional 2D mammography. Instead of viewing all of the complexities of your breast tissue in a flat image, as with conventional 2D mammography, fine details are more visible and no longer hidden by the tissue above or below.

The integrated "Fast" paddle technology accommodates the natural contour of the breast, tilting or more uniform compression and exposure, and improved patient comfort.

What are some common uses of the procedure?

Mammograms are used as a screening tool to detect early breast cancer in women experiencing no symptoms and to detect and diagnose breast disease in women experiencing symptoms such as a lump, pain or nipple discharge.

Screening Mammography - plays a central part in early detection of breast cancers because it can show changes in the breast up to two years before a patient or physician can feel them.

Diagnostic Mammography - is used to  evaluate a patient with abnormal clinical findings - such as a breast lump or lumps - that have been found by the women or her doctor. Diagnostic mammography may also be done after an abnormal screening mammography in order to evaluate the area of concern on the screening exam.

How should I prepare?

  • Do not schedule your mammogram for the week before your period if your breast are usually tender during this time.
  • Do not wear no heavy perfume deodorant , body oil or powder. These can appear on the mammogram as calcium spots.  If you do have deodorant on there are towelettes here you can use.
  • Arrive come 10-15 minutes prior to your exam. It is easiest if you wear a two-piece outfit.
  • A screening mammogram usually takes 20 minutes and can be scheduled throughout the day. A diagnostic mammogram is scheduled when the radiologist is here.


Who interprets the results and how do I get them?

A radiologist, a physician specifically trained to supervise and interpret radiology examinations, will analyze the images and send a signed report to your primary care or referring physician, who will discuss the results with you.

You will also be notified of the results from the hospital, this usually takes a few days.
