Peak area measurements for individual metabolites, from gated and nongated point-resolved spectroscopy acquisitions
| Metabolite | Peak Area (au) | P-value | |
|---|---|---|---|
| Gated | Nongated | ||
| NAA | 1225.9 ± 121.5 | 1152.8 ± 85.5 | .137 |
| Cr | 967.3 ± 107.0 | 1007.5 ± 89.6 | .375 |
| Cho | 754.0 ± 60.8 | 752.0 ± 107.1 | .959 |
Note:—NAA indicates N-acetylaspartate; Cr, total creatine; Cho, choline-containing compounds. For comparisons between gated and nongated acquisitions, P > .05 is nonsignificant. Arbitrary units, as defined in Methods.
