A comparison of calibration data from full field digital mammography units for breast density measurements
BACKGROUND Breast density is a significant breast cancer risk factor measured from mammograms. The most appropriate method for measuring breast density for risk applications is still under investigation. Calibration standardizes mammograms to account for acquisition technique differences prior to making breast density measurements. We evaluated whether a calibration methodology developed for an...
متن کاملFull Field Digital Mammography with Breast Cushions in Screening Subjects
To explore the impact of radiolucent breast cushions on breast pain and image quality of full field digital mammography (FFDM) in screening subjects. The American College of Radiology (ACR) phantom and fifty-four women were enrolled in this study. Use of cushions reduced pain (p < 0.001). The imaging quality with cushions was inferior to those without cushions in phantom studies (p ≦ 0.01), on ...
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....
متن کاملA comparison of the accuracy of film-screen mammography, full-field digital mammography, and digital breast tomosynthesis.
AIM To measure the change in diagnostic accuracy of conventional film-screen mammography and full-field digital mammography (FFDM) with the addition of digital breast tomosynthesis (DBT) in women recalled for assessment following routine screening. MATERIALS AND METHODS Ethics approval for the study was granted. Women recalled for assessment following routine screening with screen-film mammog...
متن کاملEffective x-ray attenuation coefficient measurements from two full field digital mammography systems for data calibration applications
BACKGROUND Breast density is a significant breast cancer risk factor. Currently, there is no standard method for measuring this important factor. Work presented here represents an essential component of an ongoing project that seeks to determine the appropriate method for calibrating (standardizing) mammography image data to account for the x-ray image acquisition influences. Longer term goals ...
