PURPOSE To compare the diagnostic performance of two-dimensional (2D) mammography, 2D mammography plus digital breast tomosynthesis (DBT), and synthetic 2D mammography plus DBT in depicting malignant radiographic features. MATERIALS AND METHODS In this multicenter, multireader, retrospective reading study (the TOMMY trial), after written informed consent was obtained, 8869 women (age range, 2...
Background and purpose: Dual-energy mammography technique is used for improving the accuracy of breast cancer diagnosis especially in dense breast cases and also detection of micro-calcifications which are early signs of breast cancer. The purpose of this study was to investigate the automatic separation feasibility of micro-calcification images in breast tissue images and evaluating its accura...
The substitution of digital representations for standard film/screen mammography analog images provides access to methods for digital storage and transmission and enables the use of a variety of digital image processing techniques, including enhancement and computer assisted detection and classification of abnormalities. Lossy image compression can further improve the efficiency of transmission...
A United Kingdom digital mammography national database would have major benefits for the United Kingdom. For example, such an archive could: provide a huge teaching and training resource; be able to aid in the evaluation of innovative software to compute the quality of each mammogram as it is sent to the archive; act as a significant resource for epidemiological studies; and be a tremendous ste...
Although mammography has been the gold standard for the early detection of breast cancer, if a woman has dense breast tissue, a false negative diagnosis may occur. Breast ultrasound, whether hand-held or automated, is a useful adjunct to mammography but adds extra time and cost. The primary aim was to demonstrate that our second-generation Aceso system, which combines full-field digital mammogr...
