PURPOSE To compare screen-film mammography with digital mammography in a breast cancer screening program, with a focus on the clinical relevance of detected cancers. MATERIALS AND METHODS The study was approved by the regional medical ethics review board. Informed consent was not required. Before the nationwide transition to digital mammography in the Dutch biennial screening program, the per...

The ACR's Mammography Accreditation Program has been helping facilities improve the quality of mammography through peer review and professional feedback since 1987. Initially conceived as a voluntary program, accreditation became mandatory when the Mammography Quality Standards Act (MQSA) of 1992 required all U.S. mammography facilities to become accredited and certified by October 1, 1994. Cur...

?Screening for Breast Cancer with Mammography? is a Cochrane systematic review originally published by Peter Gøtzsche and Karsten Jørgensen in 2001 and updated multiple times by 2013. In the 2013 article, the authors discuss the reliability of the results from different clinical trials involving mammography and provide their conclusions about whether mammography screening is useful in preventin...

Multiple clinical studies have demonstrated that the use of screening mammography reduces mortality from breast cancer. 2, 3 The efficacy of mammography depends upon the ability to identify cancers based on the differing absorption of x-rays in cancerous tissue compared to adipose and glandular tissue. In mammography cancers often appear ‘white’, similar to normal glandular tissue, making cance...

Breast cancer screening remains a subject of intense and, at times, passionate debate. Mammography has long been the mainstay of breast cancer detection and is the only screening test proven to reduce mortality. Although it remains the gold standard of breast cancer screening, there is increasing awareness of subpopulations of women for whom mammography has reduced sensitivity. Mammography has ...

PURPOSE To retrospectively evaluate the added value of one-view breast tomosynthesis in adjunct with mammography to characterize breast lesions. MATERIALS AND METHODS Our institutional ethics committees approved the study and granted a waiver of informed consent. One hundred fifty-five women (mean age, 51.3 years, range: 24-92 years) who systematically underwent mammography and breast tomosyn...

BACKGROUND It is important to assess access to diagnostic mammography because of the high likelihood of breast cancer among women who need diagnostic evaluation. We studied access to diagnostic mammography in the Greater San Francisco Bay Area. METHODS We identified facilities that provide diagnostic mammography in nine counties in Northern California. We tried to schedule a diagnostic mammog...
