Correlation between poststenotic parameters of extracranial distal internal carotid artery and ipsilateral cerebral hemodynamics

	Baseline rCBF (mL/100 g/min)		Post-acetazolamide rCBF (mL/100 g/min)		VR
r	P	r	P	r	P
PSV (cm/s)	0.32	.02	0.39	.006		NS
EDV (cm/s)	0.38	.006	0.42	.003		NS
TMV (cm/s)	0.38	.007	0.44	.002		NS
Diameter (mm)		NS	0.33	.02	0.40	.005
Blood flow volume (mL/s)		NS	0.48	.0006	0.39	.006

Note:—rCBF indicates regional cerebral blood flow; VR, vasoreactivity to acetazolamide; PSV, peak systolic velocity; EDV, end diastolic velocity; TMV, time-averaged mean velocity; NS, not significant.
