background: angiosarcoma can develop in all parts of the body containing blood vessels, including breast. statistically, less than 10% of all angiosarcomas originate in the breast. angiosarcoma accounts for less than 0.05% of breast primary cancers. primary angiosarcoma develops without a history of treatment for breast cancer, whereas secondary angiosarcoma develops in patients who have alread...

Goal of this research is to improve the capability of ultrasound images for detecting breast microcalcifications (MCs) and remove the major barriers of ultrasound for early breast cancer detection. The low detection rate of MCs with ultrasound is due to the low spatial resolution of the ultrasound images and to the presence of speckle noise, which masks the tiny microcalcifications. The first o...

The aim of the study was: to obtain the profile of patients (with regards to age and family history of breast cancer) with a palpable breast mass. To determine the validity of ultrasound in the assessment of the palpable breast mass by determining the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ultrasound in distinguishing a malignant mass. To ...

BACKGROUND The objective of this study was to determine whether the use of ultrasound and percutaneous breast biopsies in patients with screen-detected nonpalpable abnormalities can reduce benign open surgical biopsies of the breast without increasing cost or sacrificing detection of potentially curable breast carcinomas. METHOD Using a computerized mammography database and consecutive logs o...

Objectives. This study presents correlations between cross-sectional anatomy of human female breasts and Quantitative Transmission (QT) Ultrasound, does discriminate classifier analysis to validate the speed of sound correlations, and does a visual grading analysis comparing QT Ultrasound with mammography. Materials and Methods. Human cadaver breasts were imaged using QT Ultrasound, sectioned, ...

While there is an increasing role of ultrasound for breast cancer screening in patients with dense breast, conventional anatomical ultrasound lacks sensitivity and specificity for early breast cancer detection. In this study, we assessed the potential of ultrasound molecular imaging using clinically translatable vascular endothelial growth factor receptor type 2 (VEGFR2)-targeted microbubbles (...

CONTEXT Annual ultrasound screening may detect small, node-negative breast cancers that are not seen on mammography. Magnetic resonance imaging (MRI) may reveal additional breast cancers missed by both mammography and ultrasound screening. OBJECTIVE To determine supplemental cancer detection yield of ultrasound and MRI in women at elevated risk for breast cancer. DESIGN, SETTING, AND PARTIC...

Background: To determine the role of ultrasound as an adjunct modality to mammography in diagnosing breast cancer. Methods: Total 100 patients of breast cancer were recruited in this comparative study. These cases were subjected to mammography. Ultrasound was then performed as an adjunct modality while clinical and mammographic results were available to the radiologist evaluating the ultrasound...

OBJECTIVE This study is to investigate the diagnostic role of multi-mode ultrasound in level 4 BI-RADS breast lesions and to establish a Logistic regression model. METHODS Totally 179 patients with 182 sites of breast lesions were enrolled in this study. Preoperatively, the examinations of routine ultrasonography, elastography, contrast-enhanced ultrasonography and three-dimensional color Dop...

We report on the first study demonstrating the ability of a recently-developed, contrast-enhanced, ultrasound imaging method, referred to as cumulative phase delay imaging (CPDI), to image and quantify ultrasound contrast agent (UCA) kinetics. Unlike standard ultrasound tomography, which exploits changes in speed of sound and attenuation, CPDI is based on a marker specific to UCAs, thus enablin...
