The standard driver power of magnetic resonance elastography (MRE) in pediatric patients is recommended to be reduced by 20–50%, compared to adult patients, to keep the patients from any injury due to the vibrating driver, however, there is limited published information on driver power of MRE in pediatric applications. Furthermore, there is lack of study to evaluate whether different amplitudes of driver power may affect the measurement of liver stiffness on pediatric MRE. In this abstract, we assessed the effect of different driver power amplitudes on the measurement of liver stiffness in pediatric liver MRE.
