Optimization of Digital Mammography Resolution Using Magnification Technique in Computed Radiography
Purpose: To determine whether magnified digital mammography using a computed radiography system can produce better spatial resolution by reducing the focus-object distance, and to define the optimal magnification factor when a large x-ray tube focal spot is used for digital mammography using a CR system. Materials and Methods: Digital images obtained using computed radiography of a breast phant...
متن کاملScreening Mammography
OBJECTIVE . We evaluated the association between clinical image quality and breast cancer occurrence within 24 months of a negative mammogram. MATERIALS AND METHODS . We identified women with breast cancer who were younger than 40 years old and older and screened from January 1, 1988, through December 31, 1993. We retrospectively assigned Breast Imaging Reporting and Data System (BI-RADS) asses...
متن کاملMammography Facility Characteristics Associated With Interpretive Accuracy of Screening Mammography
BACKGROUND Although interpretive performance varies substantially among radiologists, such variation has not been examined among mammography facilities. Understanding sources of facility variation could become a foundation for improving interpretive performance. METHODS In this cross-sectional study conducted between 1996 and 2002, we surveyed 53 facilities to evaluate associations between fa...
متن کاملLetters to the Editors Screening with Mammography
Dr. Skrabanek's recent article (2) contains serious inaccuracies. In his eagerness to disprove the value of breast cancer screening with mammography, he has misinterpreted some parts of the published work and overlooked others. In particular, his attack on the Swedish Two-County trial must not go unchallenged. His first complaint is that randomization was by cluster rather than by individual. R...
متن کاملReduced screening mammography among women with diabetes.
BACKGROUND Despite regular health care, preventive health issues may be neglected in patients with chronic diseases such as diabetes. Case-control studies in the United States have shown lower mammogram rates in women with diabetes; however, it is not known whether the presence of diabetes mellitus affects mammography use in a Canadian setting, where there is universal access to health care. ...
