Proton MR spectroscopy has proven to be a valuable tool in the evaluation and detection of prostate cancer by assessing metabolite ratios incorporating choline and citrate signals. The choline peak in the proton spectrum actually consists of several different peaks of choline containing compounds[2], of which some can be distinguished using 7 Tesla 31P spectroscopic imaging. In this work we present our first patient results of a method that combines 31P and 1H within one measurement using a 31P Tx/Rx and 1H Rx endorectal coil and we show its feasibility for correlating 31P and 1H metabolite ratios.
