For noninvasive evaluation of biomedical tissue elasticity, magnetic resonance elastography (MRE) and ultrasound elastography (USE) using acoustic radiation force impulse (ARFI) have become common for use in clinical practice. However, USE-ARFI has not yet been compared with MRE. In this study, the quantitativity of MRE and USE-ARFI (VTTQ) measurement was evaluated by polyacrylamide phantoms. There was strong correlation between MRE and rheometer, and VTTQ and rheometer. VTTQ with 4 MHz convex probe showed higher standard deviation, and VTTQ and MRE showed different depth dependency. Therefore, we should consider of the properties of each method.
