Correlations between Mean CBF-Derived Lesion Volumes (mm³) at Various Time Points and 24-Hour TTC Infarct Volume in the Permanent Occlusion Groups and the CBF Volumes over Time in the Temporary Group That Could Not Be Correlated to Infarct Volume because of the Reperfusion

n = 11 in Group 1 + 2, n = 6 in Group 2, p < 0.05 was considered significant. 24-hour lesion volume represents the TTC infarct volume (mm³).

CBF = cerebral blood flow; TTC = 2,3,4-triphenyltetrazolium chloride; LV = lesion volume.
