Mammography. 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 or microcalcifications.
Breast imaging. Schematic image showing a woman undergoing a mammogram imaging examination. In medicine, breast imaging is a sub-speciality of diagnostic radiology that involves imaging of the breasts for screening or diagnostic purposes. There are various methods of breast imaging using a variety of technologies as described in detail below.
A woman having a mammogram. [edit on Wikidata] Breast cancer screening is the medical screening of asymptomatic, apparently healthy women for breast cancer in an attempt to achieve an earlier diagnosis. The assumption is that early detection will improve outcomes. A number of screening tests have been employed, including clinical and self ...
The Mammography Quality Standards Act (MQSA) was enacted by the United States Congress to regulate the quality of care in mammography. The act was officially effective in 1994, and was extended in 2004 to continue through 2007. The U.S. Food and Drug Administration (FDA) began inspections of mammography facilities to ensure compliance in 1995.
Screening mammography efficiently finds non-life-threatening, asymptomatic breast cancers and precancers, even while overlooking serious cancers. According to the cancer researcher H. Gilbert Welch , screening mammography has taken the "brain-dead approach that says the best test is the one that finds the most cancers" rather than the one that ...
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. Scintimammography is another nuclear medicine breast ...
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. The combination of CTLM and mammography is able to distinguish between benign and malignant tumors with higher accuracy. Advantages
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 ...
