PURPOSE: It has been shown that breast tomosynthesis may improve sensitivity and specificity compared to 2D mammography, resulting in increased detection-rate of cancers or lowered call-back rates. The purpose of this study is to characterize a spectral photon-counting multi-slit breast tomosynthesis system that is able to do single-scan spectral imaging with multiple collimated x-ray beams. The system differs in many aspects compared to conventional tomosynthesis using energy-integrating flat-panel detectors...

PURPOSE: Mammographic breast density is an established risk marker for breast cancer and is visually assessed by radiologists in routine mammogram image reading, using four qualitative Breast Imaging and Reporting Data System (BI-RADS) breast density categories. It is particularly difficult for radiologists to consistently distinguish the two most common and most variably assigned BI-RADS categories, i.e., "scattered density" and "heterogeneously dense". The aim of this work was to investigate a deep learning-based breast density classifier to consistently distinguish these two categories, aiming at providing a potential computerized tool to assist radiologists in assigning a BI-RADS category in current clinical workflow...

BACKGROUND: Breast cancer is a leading cause of death in the United States. Continuing medical education programs such as the American Board of Internal Medicine's Maintenance of Certification (MOC) program can increase early detection of cancers by educating physicians about the benefits of screening. Did the imposition of American Board of Internal Medicine's MOC requirement affect guideline-compliant mammography screening? METHOD: To address this question, we took advantage of a natural experiment that occurred when one group of general internists was required to complete MOC by 2001 because they initially certified in 1991 (MOC required) and another group was grandfathered out of this requirement because they initially certified in 1989 (MOC grandfathers)...

Despite changes to breast cancer screening guidelines intended to decrease screening in younger and older women, mammography rates remain high. We investigated physician attitudes towards screening younger and older women. Surveys were mailed to US primary care providers and gynecologists between May and September 2016 (871/1665, 52.3% adjusted response rate). We assessed physician (1) attitudes towards screening younger (45-49years) and older (75+ years) women and (2) recommendations for routine mammography...

OBJECTIVES: Contrast enhanced digital mammography (CEDM) is a new breast imaging technology increasingly used in the diagnostic setting but its utility in the pure screening setting has not been reported. The goal of this pilot study is to prospectively compare screening CEDM to breast MRI in women with an increased risk for breast cancer. METHODS: In this IRB-approved HIPAA-compliant study, 318 women at increased breast cancer risk were consented (December 2012-May 2015) to undergo CEDM in addition to their scheduled MRI...

Objective An increasing emphasis on preventive medicine has been supported by the recent reforms in United States health care system. Majority of the patients seen in vascular surgery clinics are elderly with more extensive medical comorbidities compared to the general population. Thus, these patients would be expected at higher risk for common malignant pathologies such as colon, breast and cervical cancer, and nonmalignant diseases such as diabetic retinopathy. This study looked at the screening compliance of vascular patients compared to data provided by Centers for Disease Control on the national and state levels...

BACKGROUND: Patients who receive an abnormal cancer screening result require follow-up for diagnostic testing, but the time to follow-up varies across patients and practices. METHODS: We used a simulation study to estimate the change in lifetime screening benefits when time to follow-up for breast, cervical, and colorectal cancers was increased. Estimates were based on four independently developed microsimulation models that each simulated the life course of adults eligible for breast (women aged 50-74 years), cervical (women aged 21-65 years), or colorectal (adults aged 50-75 years) cancer screening...

BACKGROUND: Mammography is the most common screening method for diagnosis of breast cancer. MATERIALS AND METHODS: In this study, a computer-aided system for diagnosis of benignity and malignity of the masses was implemented in mammogram images. In the computer aided diagnosis system, we first reduce the noise in the mammograms using an effective noise removal technique. After the noise removal, the mass in the region of interest must be segmented and this segmentation is done using a deformable model...

Screening has been always considered as a double-edged sword. Cancer screening could save lives in some cases, however, in other cases, it might also turn people into overdiagnosis. Overdiagnosis is the diagnosis of cancer that will never cause symptoms or death during a patient's lifetime. Therefore, overdiagnosis might lead to unnecessary treatments and lifetime surveillance, and then increase economic burden and psychological burden. In this review, we focus on how to correctly evaluate the overdiagnosis rate, and how to avoid or reduce the harms caused by overdiagnosis in the future according to the reasons associated with overdiagnosis...

Mammography is the only method presently considered appropriate for mass screening of breast cancer. However, higher breast density was strongly associated with lower mammographic sensitivity. Breast density is also identified as independent and strongest risk factors for breast cancer. Studies have shown women with high breast density have four to six times increased risk of breast cancer as compare to women with fatty breast. It varies between different age group it generally decreases with increasing age in postmenopausal women and it can be different in different ethnic groups and people from different geographical areas...

BACKGROUND: Screening tests are generally not recommended in patients with advanced cancer and limited life expectancy. Nonetheless, screening mammography still occurs and may lead to follow-up testing. OBJECTIVE: We assessed the frequency of downstream breast imaging following screening mammography in patients with advanced colorectal or lung cancer. DESIGN: Population-based study. PARTICIPANTS: The study included continuously enrolled female fee-for-service Medicare beneficiaries ≥65 years of age with advanced colorectal (stage IV) or lung (stage IIIB-IV) cancer reported to a Surveillance, Epidemiology, and End Results (SEER) registry between 2000 and 2011...

A BI-RADS category of 4 from a mammogram indicates suspicious breast lesions, which require core biopsies for diagnosis and have an approximately one third chance of being malignant. Human plasma contains many circulating microRNAs, and variations in their circulating levels have been associated with pathologies, including cancer. Here, we present a novel methodology to identify malignant breast lesions in women with BI-RADS 4 mammography. First, we used the miRNome array and qRT-PCR to define circulating microRNAs that were differentially represented in blood samples from women with breast tumor (BI-RADS 5 or 6) in comparison to controls (BI-RADS 1 or 2)...

An important limitation of conventional two-dimensional mammography is the overlap of dense breast tissue obscuring masses. Digital breast tomosynthesis (DBT) has emerged as a mammographic technology that overcomes this limitation and is considered an overall better mammogram. DBT has been shown to detect significantly more breast cancer than conventional two-dimensional mammography, and to decrease the number of callbacks for diagnostic evaluation from screening mammography. Usually the callback evaluation is deemed to be overlap of tissue requiring no further management...

Synthetic mammography (SM) consists of two-dimensional images reconstructed from digital breast tomosynthesis (DBT) data. Unlike standard full-field digital mammography (FFDM), SM does not require additional radiation exposure. SM is being introduced in breast imaging centers because early clinical data demonstrate that synthetic images are comparable to FFDM in cancer detection, positive predictive values, and recall rates. SM has completely replaced FFDM in some practices. Thus, an understanding of SM and its strengths and weaknesses compared with those of FFDM is essential...

Background A published retrospective data of our study group demonstrated that premenopausal women, patients with lobular invasive breast cancer or patients with high breast density [American College of Radiology (ACR) classification 3+4] significantly benefit from magnetic resonance imaging (MRI) leading to additional detection of malignant foci of 20.2% in the index and 2.5% in the contralateral breast, which would otherwise not be detected by routine imaging. Critics of preoperative MRI focus on higher false-positive rates leading to unnecessary surgical procedures and mastectomies...

PURPOSE: Microcalcifications are a common finding in mammography and usually require invasive procedures to diagnose or exclude malignancy. As many microcalcifications are due to benign lesions, we wanted to assess whether breast MRI as an additional diagnostic tool may be used to distinguish benign from malignant in this setting. MATERIALS AND METHODS: Eligible for this retrospective, IRB-approved observational study were 858 consecutive patients (mean age 54±11years) undergoing stereotactically-guided biopsies of suspicious mammographic microcalcifications during three year at our institution...
