Table 3.
P-Values for Differences Between MBF Estimates at Different Spatial Resolution Levels of Transmural Direction and Angular Direction Spatial Averaging in a Group of Patients (FR = Full Resolution)
| FR versus 50% of FR | FR versus 20% of FR | FR versus 10% of FR | ||
|---|---|---|---|---|
| ARMA | Transmural | 0.58 | P < 0.001 | P < 0.001 |
| Angular | 1 | 0.405 | 0.003 | |
| EXP | Transmural | 1 | 0.015 | P < 0.001 |
| Angular | 1 | 0.703 | P < 0.001 | |
| Fermi | Transmural | 8 E −02 | P < 0.001 | P < 0.001 |
| Angular | 4 E −01 | P < 0.001 | P < 0.001 | |
P-values were calculated for the null hypothesis that there is no difference between FRI values at different resolution levels, where P-values of P < 0.05 denoted significant difference.
