RATIONALE AND OBJECTIVES Diagnostic mammography is performed on women with clinical symptoms that suggest breast cancer or women for whom further mammographic evaluation has been requested because of an abnormal screening mammography. We assessed whether the use of full-field digital mammography would improve the positive predictive value (PPV) for the diagnosis of breast cancer in a diagnostic...

For the past several decades, mammography has been the cornerstone of screening for breast cancer. Technology has improved greatly, as has radiologists’ skills in interpreting fi lms. Many studies have attempted to analyze the contribution of regular mammography screening to decreasing mortality from breast cancer. These studies have demonstrated varying results. In 2001, Olsen and Gotzsche pub...

PURPOSE To assess cancer detection rates, false-positive rates before arbitration, positive predictive values for women recalled after arbitration, and the type of cancers detected with use of digital mammography alone and combined with tomosynthesis in a large prospective screening trial. MATERIALS AND METHODS A prospective, reader- and modality-balanced screening study of participants under...

Background: Breast cancer is the most common type of cancer in women demanding accurate diagnosis to take remedial measures to treat.Objective: Comparing the diagnostic capability of the computer regulation thermography (CRT), as a novel and safe diagnostic procedure, with common methods including sonography, mammography and clinical examinations for diagnosing breast cancer in suspicious...

OBJECTIVE The purpose of this work is to compare full-field digital mammography and screen-film mammography for the detection of breast cancer in a screening population. SUBJECTS AND METHODS Full-field digital mammography was performed in addition to screen-film mammography in 6736 examinations of women 40 years old and older presenting for screening mammography at either of two institutions....

Breast cancer is one of the most common cancer in the world. Early detection of cancers cause significantly reduce in morbidity rate and treatment costs. Mammography is a known effective diagnosis method of breast cancer. A way for mammography screening behavior identification is women's awareness evaluation for participating in mammography screening programs. Todays, intelligence systems could...

UNLABELLED The aim of this study is to assess the impact of multiparametric MR imaging to an exact determination of the extent of invasive ductal and lobular breast cancers in routine clinical practice.180 women aged 27-74 years (median 52.4 years) with newly diagnosed invasive ductal and lobular breast cancers confirmed by core-cut or vacuum-assisted biopsy were examined by all three imaging m...

Introduction: the objectives of this research were determination of Mean Glandular Dose in film- screen and digital mammography examinations, estimation of accumulated effective dose in some of mammography centers in Tehran city and estimating cancer risk due to these examinations. Materials and Methods: the clinical data were collected from the 1318 <...

In this paper, we present the results of mammography quality control tests related to the work with Portuguese mammography equipment, either in conventional or in digital mammography computed radiography, showing the main differences in the tested equipments. Quality control in mammography is a very special area of quality control in radiology, which demands relatively high knowledge on physics...
