Will Digital Breast Tomosynthesis Replace Conventional Mammography?

Background: Digital breast tomosynthesis (DBT) is a new modality that attempts to minimize the superimposition of overlapping tissue in the breast. By obtaining image slices of the breast at different depths, the idea is that less overlapping fibroglandular tissue will obscure a finding in the breast. Objective: To evaluate the performance of DBT compared to conventional additional mammographic views and ultrasound (US) when assessing findings from recalled screening mammograms. Methods: Patients who were recalled for findings from screening mammography that did not include calcifications were identified. When these patients presented for additional imaging for characterization of the lesion originally identified on screening mammography, they underwent the typical additional diagnostic mammographic views as well as US when necessary. The radiologist interpreted the images as per routine standard practice and rendered a BI-RADS category. In addition, the patients who agreed to be enr more...
