Correlation of BBBP values from the truncated analysis windows with BBBP values from the gold standard 90- to 240-second delayed acquisition*
| 90–120 Seconds | 90–150 Seconds | 90–180 Seconds | 90–210 Seconds | |
|---|---|---|---|---|
| Overall | 0.89 (0.81–0.97) P = .012 | 0.93 (0.89–0.98) P = .022 | 0.98 (0.96–0.99) P = .42 | 0.99 (0.99–1.00) P = 1.000 |
| Infarct | 0.85 (0.71–0.99) P = .035 | 0.94 (0.89–0.98) P = .028 | 0.98 (0.97–1.00) P = .690 | (0.99–1.00) P = 1.000 |
| Penumbra | 0.90 (0.80–1.00) P = .058 | 0.93 (0.87–1.00) P = .070 | 0.98 (0.96–0.99) P = .350 | 0.99 (0.99–1.00) P = 1.000 |
