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.
