How is 3D mammography different from traditional mammography?
While images from both technologies are read on a computer, traditional mammography creates a two-dimensional (2D) picture from two x-ray images of each breast, whereas 3D mammography takes several images from different angles to create a 3D picture of each breast. These multiple images of breast tissue slices give providers a clearer image of breast masses.
Traditional 2D mammography is still one of the most advanced tools available for detecting breast abnormalities. However, research has shown that 3D mammography detects 20-65 percent more invasive breast cancers and reduces callbacks by up to 40 percent compared to 2D mammography.
Who should get 3D mammograms?
All women should consider 3D mammography. However, 3D mammograms are particularly beneficial for women with dense breasts. With 3D mammography, a series of detailed images allow radiologists to evaluate each layer of tissue, in a sense traveling through the structure of the breast like flipping through the pages of a book. Fine details are more visible and are less likely to be hidden by overlapping tissue.
Is a referral required?
You do not need a referral to receive a 3D or 2D mammogram.
Are 3D mammograms covered by insurance?
While 3D screening mammograms are covered by many insurance plans, including Medicare, they are not yet considered the standard of care for breast cancer screening. You should check with your insurance company prior to your appointment to verify coverage.
What to expect during a 3D mammogram
Most women do not notice a difference between 3D mammography and traditional 2D mammography screenings. Both procedures take about 20 minutes, although it takes about four seconds longer to obtain each 3D image. Additionally, the process for 2D and 3D mammogram exams is the same. Your technologist will position and compress each breast, one at a time, between two plates attached to the x-ray machine. The compression lasts just long enough for the technologist to take the image, usually a few seconds. As is typical with any mammogram, some women experience minor discomfort and others experience no discomfort at all.
After your mammogram, one of our consulting radiologists will review your images. If you’ve had previous mammograms, the radiologist will compare these results to prior exams to determine if there have been any changes in your breast tissue. We will send you a letter with your results about a week after your mammogram.
