TABLE 1.
CMRGlc values determined for the test (Test) and retest (Retest) condition in each of the six major brain networks.
| Network | Test (COV) CMRGlc (umol/100 g/min) | Retest (COV) CMRGlc (umol/100 g/min) | Intrasubject variability |
| DMN | 41 ± 10 (24) | 45 ± 6 (12) | 14 ± 8 |
| L executive | 41 ± 11 (24) | 44 ± 8 (17) | 14 ± 8 |
| R executive | 40 ± 10 (26) | 42 ± 7 (16) | 13 ± 7 |
| Salience | 41 ± 10 (25) | 45 ± 6 (13) | 14 ± 9 |
| Attention | 36 ± 9 (26) | 39 ± 6 (12) | 15 ± 8 |
| Sensory-motor | 35 ± 8 (24) | 37 ± 6 (12) | 15 ± 8 |
| Average | 39 ± 10 (25) | 43 ± 6 (15) | 14 ± 8 |
The coefficient of variation (COV = mean/SD) is provided in brackets. “Average” represents the overall mean derived from all nodes across all subjects.
