CBF, cerebral blood flow; CI, confidence intervals; MCA, middle cerebral artery; s.d., standard deviation.
Ipsilateral MCA indicates the CBF measured in the seven regions of interest placed in the core MCA territory ipsilateral to the occluded carotid artery.
Contralateral MCA is measured in the opposite hemisphere.
