Slip interface imaging is a MR elastography based technique that enables assessing the mechanical connectivity between the tumor and its sourronding tissues. In this study, we have implemented a distortion-free MRE method (DIADEM-MRE) for detecting slip boundary of the prostate capsule. This technique has the great potential to be used to locate the margin of tumor adherent to the prostatic capsule, thus predicting the present of extraprostatice extension of prostate cancer.
