What Is 3D Mammography?
Digital breast tomosynthesis (3D mammography) is a revolutionary technology that gives radiologists the ability to identify and characterize individual breast structures without the appearance of overlapping tissue. During a 3D Mammography scan, multiple, low-dose images of the breast are acquired at different angles. These images are then used to produce a series of one-millimeter thick slices that can be viewed as a three dimensional reconstruction of the breast. 3D mammography combines the advantages of conventional digital mammography (2D) with a 3D perspective.
What Are The Benefits of 3D Mammography?
Instead of viewing all tissue complexities superimposed as they are on a traditional 2D mammogram, the radiologist can now scroll through the layers of the breast in one-millimeter thick slices. Reviewing breast tissue slice by slice removes the confusion of superimposed tissue allowing the radiologist to view a mammogram in a way never before possible.
Clinical studies reviewed by the FDA showed radiologists reading digital mammography (2D) plus breast mammography (3D) as compared to 2D mammography alone demonstrated superior clinical performance in specificity, fewer recalls for overlapping normal tissue on screening mammograms, and improved sensitivity, the proportion of mammograms with cancer which was correctly diagnosed.
How Do I Prepare For A 3D Mammogram?
The preparation for a 3D mammogram is identical to that of a 2D mammogram. You want to avoid wearing any kind of deodorant or lotion so the mammogram doesn't pick up any false images of your breasts. Choose a time period where you expect your breasts are least likely to be tender. If you have any questions before your appointment, reach out to your referring physician or our team at SJRA here.
