Figure 4

An array of spectra from 8 voxels within the prostate of one of the 16 patients along with reference spectra (plots in black) obtained from the spectral-quality phantom. (a) In one set of plots, those spectra obtained using standard phase encoding (red plots) were judged to be overly contaminated with lipid. The spectra obtained with PSF-Choice (blue plots), however, were judged to be free of this contamination. (b) In another set of spectra from the same patient, there was judged to be no significant difference between the two methods. Note that in both the phantom reference and in vivo spectra, the citrate resonance is inverted as expected for the parameters (TE=85ms) due to J-modulation of the strongly coupled citrate protons at 3T.
