Primary breast osteosarcoma is a rare malignancy, with mostly case reports in the literature. The appearance of breast osteosarcoma on digital breast tomosynthesis imaging has not yet been described. A 69-year-old woman presents for routine screening mammography and is found to have a calcified mass in her right breast. Pattern of calcification appeared "sunburst" on digital breast tomosynthesi...

The segmentation of a digital mammogram into breast region and film background is a necessary prerequisite in the computer-assisted diagnosis of mammograms. The segmentation method should be robust enough to handle a wide variety of digital mammograms obtained from different image acquisition systems. In addition, the large size of digitized mammograms requires an efficient image processing sys...

BACKGROUND There are no effective breast cancer education programs targeting Samoan women. We tested the effectiveness of a theory-guided, culturally appropriate breast cancer education program (the intervention) designed to increase mammography use among Samoan women. METHODS This community-based participatory cluster-randomized controlled intervention trial used a parallel two-group design....

In 2013 and 2015 combined, 5.4% of U.S. women aged 50-74 years had never received a mammogram in their lifetime. Foreign-born women were twice as likely as U.S.-born women to have never received a mammogram (9.5% versus 4.7%). Foreign-born women who lived in the United States for <25% of their lifetime were more than twice as likely to have never received a mammogram compared with those who res...

BACKGROUND Major national interventions occurred in the early and mid-1990s to increase mammography screening rates among older women. The current study examined mammography utilization by older women during this period. Relation between mammography utilization and demographic measures and health care-related factors also were examined. METHODS A cross-sectional design examined variations in ...

Two-dimensional mammography is the major imaging modality in breast cancer detection. A disadvantage of mammography is the projective nature of this imaging technique. Tomosynthesis is an attractive modality with the potential to combine the high contrast and high resolution of digital mammography with the advantages of 3D imaging. In order to facilitate diagnostics and treatment in the current...

PURPOSE The Ontario Breast Screening Program expanded in July 2011 to screen women age 30 to 69 years at high risk for breast cancer with annual magnetic resonance imaging (MRI) and digital mammography. To the best of our knowledge, this is the first organized screening program for women at high risk for breast cancer. PATIENTS AND METHODS Performance measures after assessment were compared w...

Digital Object Identifier: 10.1188/04.CJON.76-78 Mrs. S is a 60-year-old widowed woman who arrives in the emergency department via ambulance after collapsing at home. Her sister states that Mrs. S has been complaining of nausea and vomiting, polyuria, thirst, and pain in her right leg for several days. Her sister also notes that Mrs. S is lethargic and has become increasingly confused. Mrs. S h...

A new breast cancer detection algorithm, named the ―Gabor Cancer Detection‖ (GCD) algorithm, utilizing Gabor features is proposed. Three major steps are involved in the GCD algorithm, preprocessing, segmentation (generating alarm segments), and classification (reducing false alarms). In preprocessing, a digital mammogram is down-sampled, quantized, denoised and enhanced. Nonlinear diffusion is ...
