OBJECTIVE The goal of this study is to compare the overall quality of film mammograms taken according to the Korean standards with the American College of Radiology (ACR) standard for clinical image evaluation and to identify means of improving mammography quality in Korea. MATERIALS AND METHODS Four hundred and sixty eight sets of film mammograms were evaluated with respect to the Korean and...

BACKGROUND AND OBJECTIVES Because previous studies have not distinguished between intimal (atherosclerotic) and medial vascular calcification, the prevalence and clinical significance of either condition in chronic or end-stage kidney disease (CKD or ESKD) are unknown. We hypothesized that breast arterial calcification (BAC) is exclusively medial and that mammography can serve as a useful marke...

Early diagnosis of breast cancer helps to improve the successful treatment.Mammographic images are obtained from X-ray instrumentation. They are noisy and poor contrast due to ill performance of the hardware systems. Enhancement helps in improving the contrast of mammograms and reduces the false positive findings. Various enhancement techniques are available in image processing for improving th...

BACKGROUND Regular adherence to screening mammography, also known as maintenance of mammography, reduces breast cancer morbidity and mortality. However, mammography maintenance is uncommon and little is known about why women do not maintain regular screening schedules. We investigated longitudinal predictors of women not maintaining adherence. METHODS Participants were insured women enrolled ...

Pulverized bone specks and aluminum oxide specks were measured by hand into sizes ranging from 0.2 mm to 1.0 mm and then arranged in clusters. These clusters were superimposed on a human breast tissue phantom, and xeromammograms and screen-film mammograms of the clusters were made. The screen-film mammograms were digitized using a high-resolution laser scanner and then displayed on cathode ray ...

OBJECTIVE To estimate the coverage of opportunistic mammography screening performed via the Brazilian Sistema Único de Saúde (SUS, Unified Health Care System), at the state and regional level, in 2013. MATERIALS AND METHODS This was an ecological study in which coverage was estimated by determining the ratio between the number of mammograms performed and the expected number of mammograms amon...

abstractbackground: an electron beam generated x-ray spectrum consists of characteristic x-ray and continuous bermsstrahlung. the aim of this research is calculating and comparing x-ray spectra for different target filter of mammograms. materials and methods: monte carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the x-ray spectra. mcn...

A computerized method to automatically detect malignant masses on digital mammograms based on bilateral subtraction to identify asymmetries between left and right breast images was developed. After the digitization, in order to align left and right mammograms the breast border and nipple were automatically detected. Images were corrected to avoid differences in brightness due to the recording p...
