Synopsis

We hypothesize that CEST is at least as valuable as DWI and may have a potential to improve differentiation capability of malignant from benign prostatic areas as one of the combined quantitative discriminators on prostatic MR imaging. The purpose of this study was to compare the capability for distinguishing malignant from benign areas among CEST, DWIs at standard and super high b values and combined quantitative discriminator in suspected prostatic cancer patients.
