Prostate cancer (PCa) remains the most prevalent form of cancer in men. For diagnosis, Prostate-Specific Antigen (PSA) levels are most commonly used as a screening tool. Chemical shift imaging (CSI) methods can provide information on the biochemical concentrations of metabolites in different regions of the prostate. Here, we demonstrate a novel technique capable of improving the spatial and spectral resolution of the accelerated echo-planar J-resolved spectroscopic imaging (EP-JRESI) method, which obtains 2 spatial and 2 spectral dimensions in a single scan. This resolution enhanced EP-JRESI (RE-JRESI) method is evaluated in PCa patients and compared to the EP-JRESI results.
