A new setup for prostate MR Elastography is proposed that uses surface-based wave excitation by compressed-air drivers. The post-processing with tomoelastography combining wave fields at drive frequencies of 60, 70, and 80 Hz leads to highly resolved elasticity maps. A study in healthy volunteers demonstrates the good reproducibility of the method. Furthermore, the first patient results show excellent agreement with contrast-enhanced reference images, which motivates future patient studies.
