Quantification of tissue elasticity using three shear wave elastography platforms on liver fibrosis phantoms

Purpose: To assess the reproducibility of quantitative shear-wave elastography measurements, on four tissue-mimicking liver fibrosis phantoms with known Young's modulus. Materials and methods: We used three different shear wave elastography platforms: GE Logiq E9 SWE, Philips iu22 XM ARFI and Samsung RS80A. Both linear (frequency:9 MHz) and curvilinear (frequency: 7 – 1 MHz) probes were applied. The objects were four separate tissue mimicking liver fibrosis phantoms with different Young's modulus within the range of biological soft tissue (2.7kPa, 11.5kPa, 24.8kPa, 46.3kPa). Two investigators performed all measu…
