Tomosynthesis – more commonly called 3-D mammography – is now available. Using the same X-ray technology as traditional 2-D mammography, the procedure feels essentially the same for the patient. The difference is the image clarity for the radiologist who reads the mammogram. Whereas 2-D mammograms give views only from the front and side of the breast, 3-D mammograms provide images of the breast in “slices” from many different angles. Two-dimensional mammography is still a gold standard and is indicated for routine screenings. It is an excellent tool for detecting breast abnormalities.
