Traditional screening and diagnostic mammography ("2D mammography") uses x-ray technology and has been the mainstay of breast imaging for many decades. Breast tomosynthesis ("3D mammography") is a relatively new digital x-ray mammography technique that produces multiple image slices of the breast similar to, but distinct from, computed ...
Mammography (also called mastography; DICOM modality: MG) is the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast for diagnosis and screening. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses, microcalcifications, asymmetries, and distortions.
The grid ratio is the ratio of the height to the width of the interspaces (not the grid bars) in the grid. Grid ratios of 8:1, 10:1, and 12:1 are most. A 5:1 grid is most common for mammography. [5] The grid is essentially a one-dimensional Collimator and increasing the grid ratio increases the degree of collimation.
The sensitivity of mammography, CTLM and mammography + CTLM was 34.4%, 74.4% and 81.57% respectively among extremely dense breasts and 68.29%, 85.00% and 95.34% respectively among heterogeneously dense breasts. [12] The combination of CTLM and mammography is able to distinguish between benign and malignant tumors with higher accuracy.

In mammography, direct conversion FPDs have been shown to outperform film and indirect technologies in terms of resolution [citation needed], signal-to-noise ratio, and quantum efficiency. [13] Digital mammography is commonly recommended as the minimum standard for breast screening programmes .
