OBJECTIVES: This study investigated whether certain mammographic appearances of breast cancer are missed when radiologists read at lower recall rates. METHODS: Five radiologists read one identical test set of 200 mammographic (180 normal cases and 20 abnormal cases) three times and were requested to adhere to three different recall rate conditions: free recall, 15% and 10%. The radiologists were asked to mark the locations of suspicious lesions and provide a confidence rating for each decision...

Automatic segmentation of abnormal region is a crucial task in computer aided detection system using mammograms. In this work an automatic abnormality detection algorithm using mammographic images is proposed. In the preprocessing step, partial differential equation based variational level set method is employed for breast region extraction. The evolution of the level set method is done by applying mesh-free based radial basis function. The limitation of mesh-based approach is removed by using mesh-free based RBF method...

BACKGROUND: Delays in abnormal mammogram follow-up contribute to poor outcomes. In the current study, the authors examined differences in abnormal screening mammogram follow-up between non-Hispanic white (NHW) and Asian women. METHODS: The authors used a prospective cohort of NHW and Asian women with a Breast Imaging, Reporting and Data System (BI-RADS) abnormal result of category 0 or 3-plus in the San Francisco Mammography Registry between 2000 and 2010. Kaplan-Meier estimation for the median number of days to follow-up with a diagnostic radiologic test was performed, and the authors compared the percentage of women with follow-up at 30 days, 60 days, and 90 days and no follow-up at 1 year for Asian women overall (and Asian ethnic groups) and NHW women...

The long-term risk of breast cancer is increased in women with false-positive (FP) mammography screening results. We investigated whether mammographic morphology and/or density can be used to stratify these women according to their risk of future breast cancer METHODS: We undertook a case-control study nested in the population-based screening programme in Copenhagen, Denmark. We included 288 cases and 288 controls based on a cohort of 4743 women with at least one FP-test result in 1991-2005 who were followed up until 17 April 2008...

RATIONALE AND OBJECTIVES: Evidence is inconsistent about whether radiologists' interpretive performance on a screening mammography test set reflects their performance in clinical practice. This study aimed to estimate the correlation between test set and clinical performance and determine if the correlation is influenced by cancer prevalence or lesion difficulty in the test set. MATERIALS AND METHODS: This institutional review board-approved study randomized 83 radiologists from six Breast Cancer Surveillance Consortium registries to assess one of four test sets of 109 screening mammograms each; 48 radiologists completed a fifth test set of 110 mammograms 2 years later...

Computer-aided detection systems play an important role for the detection of breast abnormalities using mammograms. Global segmentation of mass in mammograms is a complex process due to low contrast mammogram images, irregular shape of mass, speculated margins, and the presence of intensity variations of pixels. This work presents a new approach for mass detection in mammograms, which is based on the variational level set function. Mesh-free based radial basis function (RBF) collocation approach is employed for the evolution of level set function for segmentation of breast as well as suspicious mass region...

In January 2005, Medicare began covering a one-time initial preventive physical examination (IPPE), also called a "Welcome-to-Medicare" visit, during a beneficiary's first 6 months under Part B. This paper examines the effects of offering Medicare IPPE coverage on the use of mammograms, breast self-exams, Pap smears, prostate cancer screenings, cholesterol screenings, and flu vaccines among beneficiaries new to Part B. We adopt a difference-in-difference estimator and estimate a set of multivariate logit models to quantify the effects of introducing Medicare IPPE coverage on the use of preventive services...

This position paper, issued by ICBR/SIRM and GISMa, summarizes the evidence on DBT and provides recommendations for its use. In the screening setting, DBT in adjunct to digital mammography (DM) increased detection rate by 0.5-2.7‰ and decreased false positives by 0.8-3.6% compared to DM alone in observational and double-testing experimental studies. The reduction in recall rate could be less prominent in those screening programs which already have low recall rates with DM. The increase in radiation exposure associated with DM/DBT protocols has been solved by the introduction of synthetic mammograms (sDM) reconstructed from DBT datasets...
