Digital breast tomosynthesis is an advancement of mammography, and has the potential to overcome limitations of standard digital mammography. This study aimed to compare first-generation digital breast tomo-synthesis including two-dimensional (2D) synthetic mammograms versus digital mammography in a population-based screening programme.
Mammography is the optimal tool to mitigate breast cancer morbidity and mortality; however, in many healthcare settings, mammography adherence rates are decreasing.
Grid artifacts occur in digital mammography when synchronization between the grid assembly and generator is not achieved, including when malfunctions occur in the grid assembly or generator subsystems. Such artifacts are not explicitly monitored or evaluated by existing mammography quality control programs. In this study, we developed an automated method for quantifying the presence of grid artifacts in two-dimensional (2D) digital mammography images and assessed its utility as a supplement to existing qual...
To evaluate the impact of comorbid conditions and age on mammography use.
The purpose of this study was to compare the all-polyethylene tibial component with the modular metal-backed component in primary total knee arthroplasty. A retrospective review of 1064 patients recorded clinical failure, as determined by need for revision surgery, range of motion, and impending radiographic loosening, as evaluated by the presence of radiolucent lines. Mean follow-up was 1.2 and 3 years, respectively. Survival in the all-polyethylene group was 100%, with 95.5% (95% CI: 85.8-98.6) survival i...
This work aimed to evaluate the use of a dose management software (DMS) in mammography and analyse the clinical practice in terms of radiation exposure in screening and diagnostic mammography.
Many breast cancer survivors fail to engage in surveillance mammography to detect new and recurrent cancers. This review identifies factors promoting or inhibiting breast cancer survivors' participation in recommended surveillance mammography.
The aim of our study was to evaluate the HER-2 status in breast cancer patients using mammography (MG) radiomics features.
Mammography is the main screening test for early detection of breast cancer; however, its access is not equal for all women in Brazil. The objective of this study was to analyze the factors associated with not having this examination done in a period of less than two years in Brazil and according to macro-region, considering sociodemographic characteristics, health conditions, lifestyle, and the use of health services.
In accordance with the Mammography Quality Standards Act, recall lay letters should be written using language that is "easily understood by a lay person." The authors hypothesized that the readability of their institution's current recall lay letter may contribute to the misinterpretation of intended time for patient return. Thus, the aim of this study was to evaluate the comprehension of the current recall lay letter statement.
In the diagnosis and detection of breast lesions, the nipple is an important anatomical landmark which can be used for registration on multi-view mammograms. In this study, we propose a new detection algorithm for nipples on digital mammography (DM) by applying pixel classification based on geometric and radiomic features extracted from breast boundary regions.
Although computer-aided diagnosis (CAD) is widely used in mammography, conventional CAD programs that use prompts to indicate potential cancers on the mammograms have not led to an improvement in diagnostic accuracy. Because of the advances in machine learning, especially with use of deep (multilayered) convolutional neural networks, artificial intelligence has undergone a transformation that has improved the quality of the predictions of the models. Recently, such deep learning algorithms have been applied...
Breast cancer screening practices and the influence of clinical guidelines or recommendations are well documented for physicians, but little is known about the screening practices of nonphysician providers (physician assistants and advanced practice registered nurses). The seven breast cancer screening guidelines or recommendations on the use of mammography have the most variation for screening average-risk women 40-49 years of age. Therefore, to better understand the practices of nonphysicians, this study ...
There is minimal survival benefit to cancer screening for those with poor clinical presentation (complex multimorbidity) or at advanced ages. The current screening mammography guidelines consider these objective indicators. There has been less attention, however, to women's subjective assessment of screening need. This study examines the interplay between complex multimorbidity, age, and subjective assessments of health and longevity for screening mammography receipt.
Breast cancer is the second most prevalent neoplasm in women after cervical cancer in Peru. It is also the third leading cause of female mortality. The implementation of screening programs using mammography has led to a considerable reduction in the mortality of this cancer in high-income countries.
Molecular breast imaging (MBI) is a relatively new technique with high sensitivity for breast cancer detection. However, because it only provides limited anatomical information, cross-correlation of MBI findings with conventional breast imaging modalities such as full field digital mammography can be challenging. We report a case of a positive MBI study in a supplemental screening setting, where cross-correlation of MBI, ultrasound, mammogram and biopsy findings was difficult. Contrast-enhanced spectral mam...
Breast cancer is the most common cancer in females worldwide. Screening with mammography for early breast cancer detection is standard community practice in many countries.
To explore the radiomics features of triple negative breast cancer (TNBC) and non-triple negative breast cancer (non-TNBC) based on X-ray mammography, and to differentiate the two groups of cases.
Contrast-enhanced mammography (CEM) is a developing modality used for the workup and management of breast cancer. Although diagnostic imaging modalities such as mammography and US have historically been the mainstays of initial breast cancer workup, recent advances in breast MRI have allowed better disease evaluation. However, MRI is not always readily available, can be time consuming, and is contraindicated in certain patients. CEM is an alternative to US and MRI, and it can be used to obtain contrast mate...
The objective of this study was to characterise thermoluminescent (TLDs) and optically stimulated luminescent dosimeters (OSLDs) at low X-ray energies and estimate the eye lens (DL), thyroid (DT) and mean glandular (DG) doses received during Full-Field Digital Mammography (FFDM) and Digital Breast Tomosynthesis (DBT). The dosimeters were characterised in mammography energies. DL, DT and DG were estimated in FFDM and DBT mode taping dosimeters on the skin of the thyroid gland and on the left eye lens of an A...
To compare diagnostic accuracy of scintimammography (SMG) and digital mammography (DS) in the diagnosis of multicentric breast cancer.
For early breast cancer detection, mammography is nowadays the commonly used standard imaging approach, offering a valuable clinical tool for visualization of suspicious findings like microcalcifications and tumors within the breast. However, due to the superposition of anatomical structures, the sensitivity of mammography screening is limited. Within the last couple of years, the implementation of contrast-enhanced spectral mammography (CESM) based on K-edge subtraction (KES) imaging helped to improve the ...
Postmenopausal obese women demonstrate an elevated breast cancer risk and experience increased breast cancer morbidity and mortality compared with women with a normal body mass index (BMI). However, to the authors' knowledge, prior studies have yielded inconclusive results regarding the effects of obesity on mammography screening adherence. Using national cross-sectional survey data, the objective of the current study was to assess the current association between increasing BMI and use of mammography screen...
To compare the comfort levels of cone beam breast computed tomography (CBBCT) and digital mammography.
Background Screening that includes digital breast tomosynthesis (DBT) with two-dimensional (2D) synthetic mammography (SM) or standard 2D digital mammography (DM) results in detection of more breast cancers than does screening with DM alone. A decrease in interval breast cancer rates is anticipated but is not reported. Purpose To compare rates and characteristics of interval breast cancer in women screened with DBT and SM versus those screened with DM alone and screen-detected breast cancer at consecutive...
