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
Nonischemic	0.91 (0.84–0.99) P = .048	0.94 (0.88–0.99) P = .061	0.98 (0.96–1.00) P = .400	0.99 (0.99–1.00) P = 1.000

Note:—BBBP indicates blood-brain barrier permeability surface product.

^*For different regions of interest and different analysis windows, correlation coefficients and their 95% CIs are given. The P values provided are for a 1-sided test for H0: correlation ≥ .980.
