3D Mammograms

The Breast Care Center at St. Joseph Hospital is one of the first women’s centers in New Hampshire to offer 3D Mammography, also called Tomosynthesis, for breast cancer screening. 3D mammograms help radiologists see breast tissue better by decreasing the effect of overlapping areas.

This process has a higher cancer detection rate than conventional mammography alone. Studies show that 3D mammograms improve detection of breast cancers with a significant reduction in recall rates.

During a 3D mammogram, 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 by radiologists as a 3D reconstruction of the breast.

Why 3d Mammograms

By offering women the latest technology in mammography, St. Joseph Hospital hopes to increase the number of local women who will be routinely screened. Statistics indicate that one in eight women will develop breast cancer sometime in her lifetime. The stage at which breast cancer is detected influences a woman’s chance of survival. The American Cancer Society states that if detected early, the five-year survival rate is 98%.
