Final infarct volumes by T2 FLAIR images acquired 24 hours post MCA occlusion were compared to baseline (i.e. 15 minutes post occlusion) angiographic measures of pial collateral recruitment. (A) Angiographic scoring of pial collateral score, Pc and (B) Arterial Arrival Time (AAT) both strongly correlated with final infarct volume. Both (C) pial collateral score, Pc, and (D) AAT are predictive the infract growth rate index, G (derived from the fits shown in Figure 3B) based on a linear function.
