An Overview of Digital Breast Tomosynthesis

Abstract

Digital breast tomosynthesis is a new imaging technology, which provides a more accurate view of the breast as compared to digital mammography. Conventional digital mammography produces a two-dimensional image of overlapping tissue, potentially obscuring malignancies. In addition, complex areas of normal tissue may be perceived as suspicious. Digital breast tomosynthesis is being implemented at breast centers throughout the country as clinical data demonstrate it addresses the limitations of conventional mammography. Studies of breast tomosynthesis have shown decreased false-positive recall rates and increased rates of cancer detection associated with the technology's ability to minimize the effect of superimposed tissue and improve lesion visibility and characterization. We have experienced favorable results with breast tomosynthesis at our facility.
