Agreement of automated softwares on infarct core volume (ICV) and hypoperfused volume for all patients
| RAPID (N=326) | iStroke (N=326) | ρ/kappa | P value | |
| CBF <30% | 6.0 (0.0–23.0) | 20.0 (5.0–35.0) | 0.68* | <0.001 |
| Tmax >6 s | 135.5 (83.8–187.5) | 131.2 (67.9–183.5) | 0.66* | <0.001 |
| ICV >70 mL | 18 (5.5%) | 17 (5.2%) | 0.73† | <0.001 |
| Mismatch volume ≥15 mL | 301 (92.3%) | 292 (89.6%) | 0.35† | <0.001 |
Data are described as n (%) or median (IQR) as appropriate.
*Spearman’s rank correlation.
†Kappa.
CBF, cerebral blood flow; Tmax, time-to-maximum.
