What is tomosynthesis in mammography?

Tomosynthesis is a 3D imaging approach in mammography that combats tissue overlap by acquiring many low-dose X‑ray images of the breast from different angles during a single compression and then reconstructing them into a stack of thin slices. This provides a quasi-3D view, so lesions or distortions that might be hidden by overlying tissue in a single 2D projection become visible on separate slices. It’s not MRI or CT—those use different technologies and typically have different dose profiles. In practice, digital breast tomosynthesis (DBT) improves cancer detection and reduces unnecessary recalls by giving clearer visualization of structures within the breast.
