FIG 2. MR spectra from the frontal lobes.
A, Proton spectra from the left frontal lobe in a control subject show normal metabolites. C, choline; Cr, creatine; N, NAA.
B, Proton spectra from the left frontal lobe in a patient with BPAD show prominent resonances between 2.1 and 2.5 ppm, corresponding to Glu/Gln (G). The resonances between 0.8 and 1.8 ppm correspond to lipids (L). C, choline; Cr, creatine; N, NAA.
