Accuracy of tissue elasticity measurement using shear wave ultrasound elastography: A comparative phantom study

Shear wave elastography (SWE) is an imaging technique using ultrafast ultrasound (20k fps) to measure tissue elasticity. This study aimed to verify the accuracy of SWE measurement compared to the gold standard and investigate the effects of size, depth, stiffness and overlapping of lesions on SWE measurements. A tissue-mimicking phantom with acoustic and shear elasticity properties similar to human breast was developed. The masses’ elasticity was measured using a commercial SWE scanner and an electromechanical microtester (gold standard). Statistically significant difference (p
