Width of decreased CBFs among the three FAIR maps with different inversion times according to the TTP difference
| wCBF | dTTP <3.2 s (%) | dTTP ≥3.2 s (%) |
|---|---|---|
| FAIR 800 < FAIR 1200 | 0/25 (0) | 0/17 (0) |

| FAIR 800 > FAIR 1200 | 2/25 (8) | 5/17 (29) |
| FAIR 800 < FAIR 1600 | 0/25 (0) | 0/17 (0) |
| FAIR 800 = FAIR 1600 | 17/25 (68) | 3/17 (18) |
| FAIR 800 > FAIR 1600 | 8/25 (32) | 14/17 (82) |
| FAIR 1200 < FAIR 1600 | 0/25 (0) | 0/17 (0) |
| FAIR 1200 = FAIR 1600 | 22/25 (88) | 5/17 (29) |
