Magnetic Resonance Elastography is an emerging alternative diagnostic tool for palpation and it is known that stiffness is altered in chronic pancreatitis and as well as in pancreatic tumors. In this study we compared performances of a drum-shaped rigid driver with a flat soft-pad passive driver in 10 volunteers at 40Hz and 60Hz diver frequencies. The variations of mean stiffness values measured between the drivers were found to be insignificant at a given frequency. Additionally, stiffness measured at 40Hz is lower compared to 60Hz. Therefore, users can make their choice of the driver based on patient comfort, longevity and cost.
