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.
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 is widely accepted as the first-line screening option for the detection of breast cancer, with a sensitivity for detection of cancer at around 85-90%. However, in patients with dense breast tissue or those with risk of breast cancer greater than 20%, the sensitivity of mammography drops significantly, with some studies reporting a ...
