DBT is a breast imaging technique that allows a volumetric reconstruction of the entire breast from a series of two-dimensional projections acquired from an X-ray tube while moving around the breast at various angles. 50° Wide-Angle Tomosynthesis overcomes diagnostic challenges like overlapping tissue with the highest depth resolution:

DBT enables better detection of expansive lesions and provides better morphological analysis of tumor masses and architectural distortions:

Fig 3: Case 1: a) Screening mammogram (2D) of a 65-year-old-woman, shows low-intensity mass posterior in the outer quarter of the right breast; b) Mammogram with tomosynthesis very clearly shows the spiculated mass; c) Magnification; d) Ultrasound reveals hypoechoic irregular mass with infiltrative features in the lower outer quarter of the right breast. US CNB: CDI, 13mm, G2, ER: 8, PR: 5, HER2: 0, Ki67: 5%, ln 0/1.

DBT effectively eliminates one of the limitations of the two-dimensional mammograms—masking of lesions caused by the superimposition of surrounding normal structures:

Fig 4: Case 2: a) Screening mammogram (2D) of a 65-year-old-woman, left breast, shows no masses or architectural distortions; b) Mammogram with tomosynthesis more clearly shows the small spiculated mass; c) Magnification; d) Ultrasound reveals small hypoechoic irregular mass with infiltrative features in the upper outer quarter of the left breast. After surgery histopathologically confirmed CDI, 6mm, G2, ER: 8, PR: 5, HER2: 0, Ki67: 5%, ln 0/1.
