Tomosynthesis, also known as 3D mammography, is used in conjunction with conventional (digital) mammography to detect breast cancers, even the most difficult to locate. With tomosynthesis, a computer produces a 3D image of your breast in one millimeter sections, allowing the radiologist to view breast tissue in greater detail – improving breast cancer detection.
Tomosynthesis is particularly effective in women with dense breast tissue or those at increased risk of developing breast cancer. Breasts are considered dense if they have a lot of fibrous or glandular tissue but not much fat. Breast density is determined by the radiologist who reads your mammogram.
