TABLE 1:

Analysis of significant differences between tumor groups at TE 30

Pairwise ComparisonsResonances Showing Significant Differences
P* < .001P* < .01P* < .05
MEN vs LGAGLXAlaGly/MI
MEN vs AAAlaCR
MEN vs GBM-METLIP09, LIP13, Ala, GLX, CR, CHO, Gly/MI
LGA vs AA
LGA vs GBM-METLIP09, LIP13, CR, Gly/MI
AA vs GBM-METLIP13, CR, CHOLIP09, Gly/MI
  • Note.—Differences of P corrected values (P*) <.05 were considered to be statistically significant. MEN indicates meningioma; LGA, low grade astrocytoma; AA, anaplastic astrocytoma; GBM-MET, glioblastoma-metastasis group; GLX, glutamate and glutamine; Ala, alanine; LIP, lipid; CR, creatine plus phosphocreatine; CHO, choline and other thmethylamine-containing compounds; Gly/MI, glycine and/or myo-inositol.

  • Only the seven resonances showing significant differences in the previously applied Kruskal-Wallis test for multiple samples were considered (LIP09, LIP13, Ala, GLX, CR, CHO, and Gly/MI).
