Typical anterior VOI MRS spectra taken from (a) a 8.4 year old and (b) a 24.4 year old monkey. The actual concentrations in i.u. for the spectrum in (a) are: NAA=9.15 i.u., Cho=1.67 i.u., tCr=11.16 i.u., MI=6.60 i.u., and for the spectrum in (b): NAA=9.04 i.u., Cho=1.47 i.u., tCR=12.98 i.u. and MI=9.3 i.u.
