Digital Tomosynthesis in the Diagnosis of Non-Palpable Breast Tumor

Abstract

Currently, in countries where early breast cancer screening is established, about 20% of breast cancer cases are diagnosed at the preinvasive stage.Comparison of diagnostic efficacy of digital tomosynthesis (DBT) and digital mammography (DM) in non-palpable breast cancer. Fifty-seven patients with histologically confirmed breast cancer were included in the study. A subjective assessment of the advantages of tomosynthesis technology for visualization of pathological signs characteristic of breast cancer (volume formation, focal asymmetry, restructuring of the structure or microcalcinates) is given. The data obtained by performing DM only and taking into account the additional information obtained by performing DBT are evaluated on the BI-RADS scale (force BI-RADS). Methods of preoperative morphological verification are often inaccessible to a wide range of patients, which leads to an increase in the number of diagnostic sectoral resections in proportion to the increase in the number of screening mammograms.
