Conventional prostate MRE uses an external driver located on the surface of the body to transmit shear waves into the prostate. However, the conventional large-diameter driver produces poorer image quality at higher frequencies. In this study we compared the performance of a large- and small-diameter Pelvic Wall driver at multiple frequencies using 2D and 3D MRE. Our results show that the smaller Pelvic Wall driver performs better than the larger driver in terms of image quality and success rate.
