The feasibility of selective NOE- and amide-CEST detection in the prostate at 7T was investigated with a multi-transmit system. Both effects can be acquired simultaneously due to the increased sensitivity and spectral resolution available at 7T. Fitted NOE- and amide-CEST were reproducible within experiments. NOE-CEST was found to be more pronounced than amide-CEST in small and whole prostate ROIs and the peripheral zone showed the lowest amide- and NOE-CEST effects.
