Spectral quality of fast 7T MR spectroscopic imaging is evaluated for multiplet compounds including Glutamine, myo-Inositol, Choline and demonstrated in brain tumor patients
FIg. 2. (A,B) Spectral data from the frontal-parietal (A) and temporal (B) regions. CRLB % are shown for several loci in the temporal study. (C1,C2) The GLU/tNAA regresses significantly with fraction GM from both studied regions. (D) The CRLB % are shown for GLU, INS and GLN for the frontal-parietal and temporal regions.
Fig. 3. (A) Regression of CRLB % with ξk=√LW/SNRk from the frontal-parietal region. (B) Same as (A) but with superimposed data from the temporal region, and magnified in X and Y axes. (C) Plots of CRk = CRLBk% * Ampk, with ξ0 =√LW*σ, with different compounds. The regressions for CRE, INS and CHO are shown.
