Two-dimensional
echo planar spectroscopic imaging (EPSI) may be used for clinical evaluation
of the human prostate. The results of EPSI studies are typically represented
as the set of MRS absorption spectra in which the concentration of each
metabolite can be determined on the basis of its frequency representation in
the voxel of interest. In addition to
frequency information, the damping characteristics of each metabolite can
also be determined by using two-dimensional Capon analysis. This damping information may be used in
conjunction with the frequency information to more easily identify
metabolites during clinical diagnosis of EPSI prostate studies.
