Tomosynthese

Abstract

Full field digital mammography (FFDM) is the most important method for early diagnosis of breast cancer. The typical overlapping of normal and pathological tissue during the standard 2D projection, however, often reduces the specificity and sensitivity of the mammographic investigation. Digital breast tomosynthesis (DBT) provides on the basis of a limited number of single images with different projection angles not superimposed tomograms and may remove the unwanted masking by superimposed structures. Clinical studies show that the digital tomosynthesis has the real potential to reduce the recall rate and simultaneously increase the cancer detection rate, especially in women with dense breasts (detection and volumetry). The use of tomosynthesis seems to be superior to full field digital mammography in mammography screening. Other possibilities of the tomosynthesis are the dual energy mammography, contrast medium-enhanced mammography and intervention.
