Abstract
The aim of this study was to determine to what extent we could identify the metabolism product peak using 3T proton magnetic resonance spectroscopic imaging MRSI of the prostate gland in healthy volunteers by combining an external array coil with Malcolm Levitt compositepulse decoupling sequence MLEVpointresolved spatially localized spectroscopy PRESSMRSI data were obtained from the entire prostate gland in six healthy volunteers The heights of the choline citrate peaks and the standard deviation SD of the noise in each voxel were calculated When the choline and/or citrate peak in a voxel exceeded 3 SD the peak was clearly identifiedThe clear citrate peak rate in the peripheral zone PZ and the central gland CG were 788 and 703 respectively The clear choline peak rate in the PZ and the CG were 554 and 449 respectively In addition the clear peak rates for both citrate and choline in the PZ and the CG were 518 and 386 Therefore in the entire prostate gland 752 had a clear citrate peak 511 had a clear choline peak and 463 had both citrate and choline peaks
