BACKGROUND In premenopausal women, the sensitivity of screening mammography for detecting breast cancer has been reported to be greater in the follicular phase than in the luteal phase of the menstrual cycle, which may be due to differences in mammographic density. To examine this possible effect, we compared mammographic density in premenopausal women who had mammograms at different phases of ...
SUMMARY: Purpose: The recent technical developments in digital as well as screen-film X-ray mammography have been reviewed in order to evaluate their clinical potential and to analyse possible lines for future development. Material and methods: The scientific literature has been reviewed, conferences covered and contacts with colleagues developed. Companies in the field have been inquired and i...
CONTEXT Annual ultrasound screening may detect small, node-negative breast cancers that are not seen on mammography. Magnetic resonance imaging (MRI) may reveal additional breast cancers missed by both mammography and ultrasound screening. OBJECTIVE To determine supplemental cancer detection yield of ultrasound and MRI in women at elevated risk for breast cancer. DESIGN, SETTING, AND PARTIC...
Ductal carcinoma in situ (DCIS) is a subtype of breast cancer encountered increasingly in clinical practice because of the widespread use of screening mammography. In the present study, we evaluated the usefulness of breast-specific g-camera (BSGC) scintigraphy in DCIS identification, describing the scintigraphic findings and their correlation with mammography and histologic subtype. Methods: T...
conclusion gm presents with a wide range of conventional radiological findings, hampering the diagnosis. in patients with inconclusive conventional findings, mri may assist in the differential diagnosis and assessment of the extent of disease. however, a definitive diagnosis and relevant treatment require histopathological confirmation. objectives the aim of this study was to review the radiolo...
background tomosynthesis is a new technology of digital mammography that enables the acquisition of a three - dimensional image and allows visualization of cancers not apparent by conventional mammography. ultrasound (us) is also used for tumor monitoring, which is highly operator dependent and has some problems with reproducibility. us is also an easily available and noninvasive modality. our ...
Purpose To estimate the benefit-to-radiation risk ratios of mammography alone, breast-specific gamma imaging (BSGI) alone, and mammography plus BSGI in women with dense breasts who were asymptomatic and examined in the 2015 study by Rhodes et al. Materials and Methods This study uses previously published breast cancer detection rates and estimates of radiation dose and radiation risk and is, th...
Abstract Background & Aim: Breast cancer is the most common type of cancer in women. Screening by mammography is the most sensitive and specific test that can be used for early detection of breast cancer. The aim of this study was to determine the state of screening by mammography and its related factors in a population of women in Rasht. Materials & Methods: This cross-sectional descriptive ...
OBJECTIVE To study the effect and clinical value of mammography in the diagnosis of breast lump so as to improve the diagnosis level of breast cancer. METHODS A retrospective analysis was carried out on clinical data of 110 patients with mammary lump confirmed by pathology to study the compliance of mammography diagnosis and Pathology diagnosis in breast lump, and the detection of microcalcif...
The present study examines women's decision making about mammography over a 1-year period, using "decisional balance," a summary of women's positive and negative perceptions about mammography derived from the Transtheoretical Model (TTM). Data were from a survey of women ages 50-74 years who completed both the baseline and 1-year follow-up telephone surveys (n = 1144) for an intervention study ...
