Prostate MR spectroscopic imaging (MRSI) is limited with long acquisition time and need for an endorectal coil. Using an acquisition-weighted spectroscopic imaging sequence with an odd symmetric sampling scheme and a sorted singular value decomposition method for spectral processing of data from a multiple receive channels, we demonstrated that in vivo prostate MRSI can be performed at 3T in a substantially reduced scan time and without using an endorectal coil. Our proposed technique has the potential to help substantially expand the clinical use of prostate MRSI.
