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.
Mammography is a common screening method, since it is relatively fast and widely available in developed countries. Mammography is a type of radiography used on the breasts. . It is typically used for two purposes: to aid in the diagnosis of a woman who is experiencing symptoms or has been called back for follow-up views (called diagnostic mammography), and for medical screening of apparently ...
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 ...
The Mammography Quality Standards Act requires mammography facilities across the nation to meet uniform quality standards. Congress passed this law in 1992 to assure high-quality mammography for early breast cancer detection, which can lead to early treatment, a range of treatment options leading to an increased chance of survival.
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.
Diffuse optical mammography, or simply optical mammography, is an emerging imaging technique that enables the investigation of the breast composition through spectral analysis. It combines in a single non-invasive tool the capability to implement breast cancer risk assessment, [ 2 ] lesion characterization, [ 3 ] therapy monitoring [ 4 ] and ...
Positron emission mammography (PEM) is a nuclear medicine imaging modality used to detect or characterise breast cancer. [1] Mammography typically refers to x-ray imaging of the breast, while PEM uses an injected positron emitting isotope and a dedicated scanner to locate breast tumors.
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 ...
