clinical application of shear wave elastography in breast masses
results of the 133 breast lesions, 32 were malignant and 101 were benign. in the differentiation of benign and malignant lesions, conventional us resulted in sensitivity of 100 %, specificity of 43.0 %, ppv of 57.1 %, npv of 36.7 %, and accuracy of 100 %. regarding swe, the sensitivity, specificity, ppv, npv, and accuracy values based on emax were 84.4 %, 89.1 %, 71.1 %, 94.7 %, and 88.0 %, res...
متن کاملShear-wave elastography for breast masses: local shear wave speed (m/sec) versus Young modulus (kPa)
PURPOSE To evaluate and compare the performance of shear-wave elastography (SWE) for breast masses using the local shear wave speed (m/sec) vs. Young modulus (kPa). METHODS A total of 130 breast lesions in 123 women who underwent SWE before ultrasound- guided core needle biopsy or surgical excision were included. With the region-of-interest placed over the stiffest areas of the lesion on SWE,...
متن کاملEvaluation of the diagnostic function of shear wave elastography in the differentiation of malignant and benign breast masses and its relationship with histological factors
Background: Shear wave elastography (SWE) estimates the stiffness of a mass based on the velocity of shear wave propagation by sound waves. Due to higher cell density and angiogenesis, malignant masses have higher stiffness than benign ones. Methods: The present study was a prospective study and was performed on patients who were referred to Ahvaz Golestan Hospital with breast mass during Marc...
متن کاملPerformance of Shear Wave Elastography for Differentiation of Benign and Malignant Solid Breast Masses
OBJECTIVES To perform a meta-analysis assessing the ability of shear wave elastography (SWE) to identify malignant breast masses. METHODS PubMed, the Cochrane Library, and the ISI Web of Knowledge were searched for studies evaluating the accuracy of SWE for identifying malignant breast masses. The diagnostic accuracy of SWE was evaluated according to sensitivity, specificity, and hierarchical...
متن کاملApplication of 3D and 2D quantitative shear wave elastography (SWE) to differentiate between benign and malignant breast masses
As breast cancer tissues are stiffer than normal tissues, shear wave elastography (SWE) can locally quantify tissue stiffness and provide histological information. Moreover, tissue stiffness can be observed on three-dimensional (3D) colour-coded elasticity maps. Our objective was to evaluate the diagnostic performances of quantitative features in differentiating breast masses by two-dimensional...
