Quality metrics of the voxels. Signal to Noise Ratio (SNR) calculated with the height of the tNAA peak to the signal at 0 to -2 ppm. Linewidth is the width of the water peak in Hz. Both calculated using FID-A12. Values are means with standard deviations in brackets.
| Small voxel | Large voxel full SNR | Large voxel with matched SNR | Small vs. large with full SNR | Small vs. large with matched SNR large | |
|---|---|---|---|---|---|
| SNR | 38.15 (6.53) | 75.45 (34.87) | 38.82 (7.96) | t(17) = 5.10, p < 0.0001 | t(17) = 0.43, p = 0.67 |
| Linewidth (Hz) | 8.14 (0.65) | 12.33 (2.41) | 12.29 (2.44) | t(17) = 8.13,p < 0.0001 | t(17) = 7.91, p < 0.0001 |
