TL;DR: MRI consistently demonstrates the presence of all TNBC with a higher level of accuracy compared with other tumour sub-types, and provides a reliable baseline for neoadjuvant chemotherapy (NAC) follow-up, and preliminary studies suggest that MRI may predict complete NAC response in TNBC more sensitively than other methods.

TL;DR: A new approach to breast parenchymal pattern classification is presented, which uses texture models to capture the mammographic appearance within the breast area and is modelled as a statistical distribution of clustered, rotationally invariant filter responses in a low dimensional space.
Abstract: Breast parenchymal density has been found to be a strong indicator for breast cancer risk, however, to date, measures of breast density are qualitative and require the judgement of the radiologist. Objective, quantitative measures of breast density are crucial tools for assessing the association between the risk of breast cancer and mammographic density as well as for quantification of density changes to the breast. Various schemes have been proposed for classifying breast density patterns, though again each requires the judgement of the clinician to assign a particular region of tissue to its class and so it is time-consuming and prone to inter- and intra-radiologist disagreement. Motivated by recent results in texture classification, we present a new approach to breast parenchymal pattern classification. The proposed scheme uses texture models to capture the mammographic appearance within the breast area: parenchymal density patterns are modelled as a statistical distribution of clustered, rotationally invariant filter responses in a low dimensional space. This robust representation can accommodate large variations in intra-class mammogram appearance and can be trained in a straight-forward manner. Key to the approach is that parenchymal patterns can occupy disconnected regions in feature space. Objective descriptors of breast density based on the digital mammogram, are developed and validated.

TL;DR: Bilateral whole-breast US complements mammography in the preoperative evaluation of patients with breast cancer and the effect of US information on therapeutic decisions is evaluated.
Abstract: PURPOSE: To evaluate the efficacy of preoperative bilateral whole-breast ultrasonography (US) in the detection of additional multifocal, multicentric, and contralateral cancers and the effect of US information on therapeutic decisions. MATERIALS AND METHODS: Two hundred one patients who had newly diagnosed breast cancer or who were suspected of having breast cancer underwent US examination of the ipsilateral and contralateral breasts with a 10-, 12-, or 13-MHz transducer. All solid lesions found at US alone were classified according to level of suspicion and were selected for biopsy. The US results were compared with mammographic findings. Sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: In ipsilateral breasts, US depicted 194 (97%) of 201 foci of invasive cancer and 52 (75%) of 69 foci of ductal carcinoma in situ (DCIS), whereas mammography and physical examination depicted 173 (86%) foci of invasive cancer and 56 (81%) foci of DCIS. In the contralateral bre...

TL;DR: Although mammography use increased for some groups between 1993 and 2005, low-income, uninsured women continued to have the lowest screening rates in 2005 and the disparity for this group was not reduced, resulting from possible declines in mammography even for uninsured women not in poverty.
Abstract: Objective:To examine current disparities in mammography use, and changes in disparities over time by race, ethnicity, income, insurance, and combinations of these characteristics.Research Design:Comparison of cross-sectional surveys of mammography use using the 1993 and 2005 National Health Intervie
