We present our first in-vivo prostate cancer case using the trans-perineal MR elastography (MRE) method. An improved rapid imaging sequence is used to acquire waves in 3D in the entire prostate gland. The mechanical waves efficiently transferred to the entire prostate via the perineum at 70Hz. The results show that the tumours are clearly distinguishable in the viscoelastic maps and that they correlate closely with histopathology. To the best of our knowledge, this is the first in-vivo prostate cancer MRE study where the viscoelastic maps are compared to whole-mount histopathology. These results show the potential for MRE to improve staging of prostate cancer tumours.
