Radiographic techniques in screen‐film mammography
The objectives of this study were to document imaging physics parameters associated with mammography physics surveys, and investigate how the choice of tube potential affects average glandular dose (AGD) and x-ray exposure time. Data from 60 mammography units were obtained pertaining to representative values of mAs, exposure time, half value layer, AGD and film density when acquiring phantom im...
متن کاملMethods of Representing Implied Author and Implied Reader in GavKhuni and its Film Adaptation
Implied author and implied reader are components of a narrative structure, playing a crucial role in illuminating hidden elements within a text. Therefore, studying these elements in literary works can expose the underlying layers of narration and open up new critical outlooks to the readers. Furthermore and in cases of cinematic adaptations, it explains whether this was the novel or the film t...
متن کاملDiagnostic performance of digital versus film mammography for breast-cancer screening.
BACKGROUND Film mammography has limited sensitivity for the detection of breast cancer in women with radiographically dense breasts. We assessed whether the use of digital mammography would avoid some of these limitations. METHODS A total of 49,528 asymptomatic women presenting for screening mammography at 33 sites in the United States and Canada underwent both digital and film mammography. A...
متن کاملScreen-Film Mammography and Soft-Copy Full-Field Digital Mammography: Comparison in the Patients with Microcalcifications
OBJECTIVE We wanted to compare the ability of screen-film mammography (SFM) and soft-copy full-field digital mammography (s-FFDM) on two different monitors to detect and characterize microcalcifications. MATERIALS AND METHODS The images of 40 patients with microcalcifications(three patients had malignant lesion and 37 patients had benign lesion), who underwent both SFM and FFDM at an interval...
متن کاملComparison of calcification specificity in digital mammography using soft-copy display versus screen-film mammography.
OBJECTIVE The purpose of this study was to compare specificity in the interpretation of calcifications in soft-copy reviewing of digital mammograms versus hard-copy reviewing of screen-film mammograms. MATERIALS AND METHODS A total of 130 consecutive cases with calcifications (44 malignant and 86 benign) that had been evaluated with needle or surgical biopsy were collected. Both screen-film m...
