MRE generates quantitative information of shear modulus. Several challenges exist for the assessment of prostate. Difficulties with wave propagation due to the central location of the prostate, have induced the development of different techniques including transurethral and endorectal drivers. The objectives of this work were to study the 3.0 Tesla trans-pelvic MRE performance in PCa at a standard excitation frequency (⍵) of 60 Hz, as well as the reproducibility of µ at different ⍵ values. In 43 patients, the MRE were acquired using five 2D-SE sequences (⍵ values: 40, 50, 60, 70 and 80 Hz) and GRE 2D sequences
