Article Synopsis
- - The study compares two different digital breast tomosynthesis (DBT) methods for breast cancer monitoring in patients with a history of breast cancer: 2-view 2D digital mammography with 2-view DBT versus 1-view digital mammography with 1-view DBT.
- - An analysis of clinical performance using real patient images showed that both DBT implementations had similar results regarding sensitivity, specificity, and area under the curve, regardless of lesion types or breast density levels.
- - The study suggests considering the 1-view methods for breast cancer surveillance due to lower radiation exposure, but further research with larger samples is needed to reach a solid conclusion.
Purpose: Breast cancer brain metastasis (BCBM) represents a major clinical challenge. Can MRI help in advancements in the management of BCBM? This review discusses MRI developments and the corresponding potential advancements in BCBM management.
Methods: An exhaustive literature search was undertaken to identify studies which look into the potential of MRI in BCBM management.
Digital breast tomosynthesis (DBT) is currently under consideration for replacement of, or combined use with 2D-mammography in national breast screening programmes. To investigate the potential benefits that DBT can bring to screening, the threshold detectable lesion diameters were measured for different forms of DBT in comparison to 2D-mammography. The aim of this study was to compare the threshold detectable mass diameters obtained with narrow angle (15°/15 projections) and wide angle (50°/25 projections) DBT in comparison to 2D-mammography.

Noise power spectra (NPS) and modulation transfer function curves (MTF) were measured for planar modes and for the first and central projections for DBT modes. In DBT mode, the x-ray beam was blocked for the projections before the central projection in order to remove the influence of lag and ghosting from the previous images.

The aim of this study was the comparison of the detection of microcalcification clusters by human observers in simulated breast images using 2D-mammography, narrow angle (15°/15 projections) and wide angle (50°/25 projections) DBT. The effects of the cluster height in the breast and the dose to the breast on calcification detection were also tested.
