Monte Carlo simulations of digital images of the contrast detail phantom and the ACR phantom are presented for two different x-ray digital mammography modalities: a synchrotron mammography system and a next-generation scanning slot clinical system. A combination of variance reduction methods made it possible to simulate accurate images using real pixel dimensions within reasonable computation t...

Breast cancer is the most common malignancy in women and early detection is important for its successful treatment. The aim of this study was to investigate the sensitivity and specificity of three methods for early detection of breast cancer: breast magnetic resonance imaging (MRI), digital mammography, and breast tomosynthesis in comparison to histopathology, as well as to investigate the int...

Introduction: Most studies in mammography have only been carried out in a comparison of image quality and lesion detection in film-screen mammography (FSM) and full field digital mammography (FFDM) systems. The aim of this paper was to evaluate mean glandular dose (MGD) of patient and affecting factors by FSM and FFDM to estimate which one gives a brief radiation protection to patient. Material...

BACKGROUND Billing data, such as Medicare claims, are a potential data source for evaluative studies of new digital mammography technologies, such as digital mammography and computer-aided detection (CAD). OBJECTIVE To assess the internal validity of procedure codes on Medicare claims for screening mammography interpreted with either digital mammography or CAD. STUDY DESIGN We assessed agre...

Detection of breast cancers with mammography is a challenging task. Images must be of high quality if cancers are to be found at the earliest possible time. This motivates the need for a quality assurance program. It has long been recognized that the performance of a complex imaging system such as mammography can drift over time and, therefore, quality control procedures must be in place to ens...

OBJECTIVE To compare between the American College of Radiology (ACR) accreditation phantom and digital mammography accreditation phantom in assessing the image quality in full-field digital mammography (FFDM). MATERIALS AND METHODS In each week throughout the 42-week study, we obtained phantom images using both the ACR accreditation phantom and the digital mammography accreditation phantom, a...

Fujifilm’s third generation full field digital mammography (FFDM) system, ASPIRE Cristalle, is based on Fujifilm’s unique and innovative technologies that achieve optimum image quality at very low patient dose. These outcomes are made possible by a new detector technology that uses a hexagonal close pattern (HCP) architecture, coupled with analytical and adaptive image processing that automatic...
