Overview

DBT acquires multiple low dose projections during a sweep to reconstruct thin slices improving lesion conspicuity over two dimensional mammography.

Technique

Reconstruction algorithms and slice thickness affect detection. DBT is often combined with synthetic two dimensional images to reduce dose.

Clinical Uses

Used for screening and diagnostic workup to reduce recall rates and improve cancer detection in dense breasts.

Limitations and Safety

Slightly higher dose than standard two dimensional mammography. Interpretation requires training and workflow adjustments.
