Echo Planar Spectroscopic Imaging with Peak-Enhanced 2D-Capon Analysis for Prostate Studies

Fred J. Frigo¹, Andreas Ebel¹

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.
