Purpose: Elastic properties of circumscribed tissue e.g. tendons, lymph nodes, myometrium are in focus of clinical interest. Current elastography systems employ several measurement techniques regarding the application of radiation force, measurement and imaging. The purpose of the study is the comparison of reliability and validity of Acoustic-Radiation-Force-Impulse (ARFI)-quantification versus Shear-Wave-Elastography (SWE) and the assessment of precision of SWE with variable Region-Of-Interest (vROI) in elasticity phantoms. Material and methods: The ultrasound (US) elastography phantom Model 049 (CIRS, USA) wa…
