PURPOSE OR OBJECTIVE To evaluate the performance of Comb-push Ultrasound Shear Elastography (CUSE) for classification of breast masses. MATERIALS AND METHODS CUSE is an ultrasound-based quantitative two-dimensional shear wave elasticity imaging technique, which utilizes multiple laterally distributed acoustic radiation force (ARF) beams to simultaneously excite the tissue and induce shear wav...

The aim of our study was to find effective features of mammography and ultrasound in differentiating Basal-like breast cancer (BBC) and Normal-like breast cancer (NBC), two subtypes of triple negative breast cancer (TNBC). From January 2014 to March 2017, we retrospectively reviewed 91 patients who were pathologically confirmed as TNBC. According to immunohistochemical cytokeratin 5/6 (CK5/6) a...

BACKGROUND Elastography is an imaging technique, which displays the hardness of soft tissue, by showing the behavior of tissue when subjected to mechanical stress. The purpose of this study was to assess the role of ultrasound elastography in differential diagnosis of breast lesions. MATERIALS AND METHODS A prospective study was conducted in our Research Centre, University of Medicine and Pha...

The aim of this study was to investigate the accuracy of imprint cytology (IC) of breast core biopsy under ultrasound guidance and to assess the value of a rapid on-site preliminary diagnosis of breast lesions. A total of 437 breast core needle biopsies under ultrasound guidance with touch imprint cytology, histology, and final diagnosis were reviewed. These cases were collected from archived f...

AIM The purpose of this study is to describe our experience with needle localization technique in diagnosing small breast cancers. MATERIAL AND METHODS This retrospective study included a hundred and twenty patients' with impalpable breast lesions and they underwent wire localization. All patients had mammography, ultrasound exam and pathohystological results. We use Mammomat Inspiration Siem...

Breast cancer is the second most dominant kind of among women. Ultrasound images (BUI) are commonly employed for detection and classification abnormalities that exist in breast. The ultrasound necessary to develop artificial intelligence (AI) enabled diagnostic support technologies. For improving performance, Computer Aided Diagnosis (CAD) models useful breast classification. current advancemen...

OBJECTIVE To evaluate the diagnostic performance of shear-wave elastography (SWE) for the differential diagnosis of breast papillary lesions. METHODS This study was an institutional review board-approved retrospective study, with a waiver of informed consent. A total of 79 breast papillary lesions in 71 consecutive women underwent ultrasound and SWE prior to biopsy. Ultrasound features and qu...

PURPOSE Tumor grading is an important part of breast cancer diagnosis and currently requires biopsy as its standard. Here, the authors investigate quantitative ultrasound parameters in locally advanced breast cancers that can potentially separate tumors from normal breast tissue and differentiate tumor grades. METHODS Ultrasound images and radiofrequency data from 42 locally advanced breast c...

Breast lesion is a malignant tumor that occurs in the epithelial tissue of breast. The early detection breast lesions can make patients for treatment and improve survival rate. Thus, accurate automatic segmentation from ultrasound images fundamental task. However, effectively still faced up with two challenges. One characteristics lesions’ multi-scale other one blurred edges difficult. To solve...

Male breast cancer is a rare disease in the male breast whereas gynecomastia is quite common. An elevation of the estrogen-to-androgen ratio increases the risk of both of these diseases. However, a connection between gynecomastia and subsequent breast cancer development is controversial and unclear. Imaging studies including mammography and ultrasound provide valuable information in leading to ...
