Figure 3. — Lesion volume (mL) correlation between CT perfusion RAPID (CTP-RAPID) ischemic core (CBF <30%) and manual segmentation from follow-up imaging. (a) All cases (n = 89). (b) Patients imaged <6 h from symptom onset (n = 51). (c) Patients imaged 6–24 h from symptom onset (n = 38). (d) Bland-Altman plot of agreement between lesion volume estimates of CTP-RAPID and final infarct volumes in the 6–24 h time window.
