Purpose: Recommended surveillance for BRCA1 and BRCA2 mutation carriers includes regular mammography and clinical breast examination, although the effectiveness of these screening techniques in mutation carriers has not been established. The purpose of the present study was to compare breast magnetic resonance imaging (MRI) with ultrasound, mammography, and physical examination in women at high...
The use of BIRADS classification has been recommended in sonomammography examinations in Poland since the year 2010. It was developed by the Polish Ultrasound Society and published in Ultrasound Examinations Standards of the Polish Ultrasound Society. Standards, based on BIRADS-usg classification, introduced uniformity in breast ultrasound examination descriptions and in the terminology of path...
Objectives:To correlate between the breast ultrasound imaging features and molecular subtypes of cancer to assess predictive value their correlation
Ultrasound complements mammography as an imaging modality for breast cancer detection, especially in patients with dense breast tissue, but its utility is limited by low diagnostic accuracy. One emerging molecular tool to address this limitation involves contrast-enhanced ultrasound using microbubbles targeted to molecular signatures on tumor neovasculature. In this study, we illustrate how tum...
Ultrasound-guided vacuum-assisted breast biopsy (VABB) is regarded as a feasible, effective, minimally invasive and safe method for the removal of benign breast lesions, without the occurrence of serious complications. The aim of this study was to evaluate the feasibility, efficacy and safety of ultrasound-guided VABB using the Mammotome® biopsy system in the treatment of breast lesions. The cl...
To increase the survival rates of patients with breast cancer, an ultrasound imaging system must detect tumors when they are small, with a diameter of 5 mm or less. This requires an understanding of how propagation of ultrasound energy is affected by the complex structure of the breast. In this paper, a Finite-Difference Time-Domain (FDTD) method is developed to simulate ultrasound propagation ...
The idea of an automated whole breast ultrasound was developed three decades ago. We present our initial experiences with the latest technical advance in this technique, the automated breast volume scanner (ABVS) ACUSON S2000(™). Volume data sets were collected from 50 patients and a database containing 23 women with no detectable lesions in conventional ultrasound (BI-RADS(®)-US 1), 13 women w...
PURPOSE To assess the diagnostic accuracy of mammography, ultrasound, and magnetic resonance imaging (MRI) of the breast in the surveillance of women at high risk for breast cancer. EXPERIMENTAL DESIGN In this prospective comparison study, women at high risk for breast cancer were offered annual surveillance examinations, consisting of mammography, ultrasound, and MRI, at a single tertiary ca...
Breast cancer must be detected early to reduce the mortality rate. Ultrasound images can make it easier for clinician diagnose cases of dense breasts. This study presents a deep vision transformer-based approach predicting breast malignancy scores from ultrasound images. In particular, various state-of-the-art transformers such as BEiT, CaiT, Swin, XCiT, and Vis-Former are adapted trained extra...
Breast ultrasound is an important complement to the clinical/mammographic investigation of breast lesions. This operator-dependent method entails real-time image detection and analysis and requires extensive training and experience in identifying and differentiating between benign and malignant lesions (1-4). Lesion contour and shape are considered to be the main features that allow differentia...
