The aim of the study is to evaluate the added value of digital breast tomosynthesis (DBT) in the characterization of breast lesions.
All patients enrolled in the study will undergo both 2D digital mammography and digital breast tomosynthesis (DBT), using standardized protocols. The DM plus DBT acquisition commonly referred to as "combo" mode , that has shown an improvement in specificity and sensitivity , but at approximately doubling of the radiation dose . This approach will provide a consistent framework for evaluating the diagnostic capabilities of both techniques in characterizing breast masses.

In digital breast tomosynthesis (DBT), images are acquired using a specialized X-ray tube that moves in an arc around the breast. This technique captures multiple low-dose images from various angles, typically within a 15° to 60° range. These images are then reconstructed into 1-mm slices to create a 3D representation of the breast, allowing for detailed layer-by-layer evaluation. The number of images acquired varies depending on the size of the breast and the specifications of the equipment but generally ranges from 10 to 25 projections, captured within a few seconds.
