^aMean CBV values in the regions of interest within the infarcted territory (infarct) and in the normal contralateral side (normal) in the 10 canine experiments.

^bPaired 2-sample t test.

^c1 indicates 1 mL/s; C-arm 1, values from the first C-arm CT acquisition.

^dC-arm 2 indicates values from the second C-arm CT acquisition.
