During the 3D part of the exam, the X-ray arm sweeps in a slight arc over your breast, taking multiple breast images. Then, a computer produces a 3D image of your breast tissue in one millimeter slices, providing greater visibility for the radiologist to see breast detail in a way never before possible. They can
scroll through images of your entire breast like pages of a book. The additional 3D images make it possible for a radiologist to gain a better understanding of your breast tissue during screening1, significantly improving early breast cancer detection2-4 and
providing the confidence to reduce the need for follow-up imaging by up to 40 percent.4-5
With conventional digital mammography, the radiologist is viewing all the complexities of your breast tissue in a one flat image. Sometimes breast tissue can overlap, giving the illusion of normal breast tissue looking like an abnormal area. By also looking at the breast tissue in one millimeter slices,
the radiologist can provide a more accurate exam.2 In this way, 3D mammography finds 40 percent more invasive cancer missed with conventional 2D mammography.2-4 It also means there is less chance your doctor will call you back later for a “second look,” because now they can
see breast tissue more clearly.4-5
A screening mammogram is your annual mammogram that is done every year. Sometimes the radiologist may ask you to come back for follow-up images which is called a diagnostic mammogram to rule out an unclear area in the breast or if there is a breast complaint that needs to be evaluated.
3D mammography complements standard 2D mammography and is performed at the same time with the same system. There is no additional compression required, and it only takes a few more seconds longer for each view.
Very low X-ray energy is used during the exam, just about the same amount as a traditional mammogram done on film.
