Measuring shear-wave speed with point shear-wave elastography and MR elastography: a phantom study
OBJECTIVES To compare shear-wave speed (SWS) measured by ultrasound-based point shear-wave elastography (pSWE) and MR elastography (MRE) on phantoms with a known shear modulus, and to assess method validity and variability. METHODS 5 homogeneous phantoms of different stiffnesses were made. Shear modulus was measured by a rheometer, and this value was used as the standard. 10 SWS measurements ...
متن کاملThree dimensional shear wave scattering MR elastography
Introduction: Magnetic resonance elastography (MRE) is a non invasive method that combines externally applied vibrations with the motion sensitivity of MRI to measure the shear elasticity soft tissues [1]. In MRE this is traditionally achieved by solving an inverse problem with MRE shear wave images as input data [2]. A complementary approach, which does not require the solution of an inverse p...

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 کاملCan continuous scans in orthogonal planes improve diagnostic performance of shear wave elastography for breast lesions?
BACKGROUND Static shear wave elastography (SWE) is used to detect breast lesions, but slice and plane selections result in discrepancies. OBJECTIVE To evaluate the intraobserver reproducibility of continuous SWE, and whether quantitative elasticities in orthogonal planes perform better in the differential diagnosis of breast lesions. METHOD One hundred and twenty-two breast lesions schedule...
