Defining 3D Mammography

Defining 3D Mammography 

3D mammography, also known as breast tomosynthesis, is an exciting advancement in the screening and diagnosis of breast cancer that allows your radiologist to see your breast tissue in more detail than ever before possible.

The sophistication of this technology will provide you with peace of mind, knowing that any abnormalities can be detected earlier, with less need for you to return for additional imaging.

The 3D Mammography Difference

Digital mammography is one of the most advanced tools available in the detection of breast cancer. While a two-dimensional digital exam produces a clearer image than film mammography, it only provides one condensed view of the breast tissue.

This condensed image of overlapping breast tissue can hide the fine details your radiologist uses to find the subtle signs of cancer in an early stage.

A More Revealing Look

A 3D scan allows your radiologist to view your breast tissue one layer at a time. Rather than one flat, dense image, your radiologist can examine your breast tissue in one millimeter layers, making it easier to interpret any abnormalities.

By compiling these layers into a 3D model, your radiologist is able to see a more complete picture of your breast health. A more complete picture helps to better detect cancer and reduce the number of false positives.

What to Expect During Your Scan

During your exam the technologist will position you, compress your breast under a paddle and take images from different angles. As the tomosynthesis part of the exam begins, the X-ray arm sweeps in a slight arc over the breast, taking multiple images in just seconds.

A tomosynthesis exam is very similar to a traditional digital mammogram, and could complement your regular mammogram, not replace it.

Review in Real Time

Unlike film mammography which takes time to process, your technologist is able to review your digital scan in real time. This helps ensure that adequate images are captured for your radiologist at the time of your exam, helping you avoid return visits for additional scans.

Benefits of 3D Mammography
  • More accurate and earlier detection of abnormalities, especially for women with dense breasts
  • Designed for a more comfortable patient experience
  • Reduced anxiety associated with call backs for additional scans
