Digital Breast Tomosynthesis Screening

Digital breast tomosynthesis (DBT) has been shown to be a promising imaging technique for breast cancer detection. DBT involves acquisition of a series of images in different planes over a limited angular range, and their subsequent reconstruction into a quasi-three-dimensional breast volume. This reduces the effects of tissue overlap. This review aims to describe the key features of DBT, including technique, results from recent retrospective and prospective clinical studies, and issues with DBT as a screening tool.
