Purpose
The role of digital breast tomosynthesis (DBT) in clinical practice has been increasing continuously over the last decade. A number of early clinical studies has showed a higher accuracy of DBT compared to standard full-field digital mammography (FFDM) [1-4]. In screening with mammography the sensitivity to nonpalpable cancer in women with dense breasts is as low as 30-48% [5]. The term breast density refers to the relative amount of radiopaque epithelial and stromal tissue elements compared with the amount of radiolucent fatty elements seen in mammography [6]. In the newest 5th edition of Breast Imaging Reporting and Data System (BI-RADS) Atlas American College Radiology (ACR) replaced the description of breast density - from numbers to letters 1-A, 2-B, 3-C, 4-D [7]. Higher breast density is reported to be one of the main risk factors for breast cancer (BC) [8-9].
Our purpose was to evaluate and to compare diagnostic characteristics (sensitivity and specificity) of digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM) in detection of breast cancer (BC) presenting as a mass in women with dense breasts (categories C and D according BI-RADS Atlas).
