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 کاملDigital versus screen film mammography: a clinical comparison
Breast carcinoma is the most common malignancy among women in developed countries, and its incidence is on the rise in developing countries. In Malaysia, it accounts for about 30% of newly-diagnosed female cancers [1]. Imaging of the breast can be traced to its earliest origins in 1913 when a surgeon, Albert Salomon, used radiography images of mastectomy specimens to demonstrate the spread of b...
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...
متن کاملClinical comparison of full-field digital mammography and screen-film mammography for detection of breast cancer.
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....
