Abstract

We provide the examination technique and the normal values of the cerebral blood flow velocity assessed with the transcranial doppler ultrasound system (TC2-64B, EME) operating at 2MHz in 50 volunteer adult subjects who had no history of neurological illness. Their age ranged from 20 to 58 years and 30 were men. We examined the middle cerebral artery (MCA), the anterior cerebral artery (ACA), the posterior cerebral artery (PCA), the internal carotid (ICAl the opthalmic artery (OPA), and the basilar artery (BA). For each artery we analyzed peak systolic, peak diastolic. And mean flow velocity. Reference values of mean velocities (cm/sec) were 53.2-58.5 for MCA; 48.7-53.8 for ACA; 30.8-33.2 for PCA; . 38.6-42.5 for ICA;11.7-13.1 for OPA;and 34.2-39.9 for BA (95% confidence interval). The velocities correlated inversely with age (p<0.05) arld were significantly lower in the posterior circulation (PCA and BA) than in anterior circulation (MCA, ACA and ICA). There was no difference between both.sexes and between the right and the left side.
