Just as chest CT offers advantages over standard chest X-rays, the image clutter created by overlapping objects in two-dimensional X-rays is reduced in cross-sectional three-dimensional tomosynthesis images, significantly reducing the likelihood of missing tumors. This is particularly important in women with denser mammograms, those with prominent fibrocystic structures, and those who have not yet gone through menopause. In these cases, there are numerous structures within the breast that can hide behind breast cancer, with densities similar to those of the cancer itself. Tomosynthesis overcomes this problem. Tomosynthesis reduces the number of undecided cases and the rate of unnecessary biopsies.
