title: Transcranial Doppler ultrasound. Examination technique and normal reference values.
abstract: A newly developed Transcranial Doppler system (TCD) has been used in a group of subjects without any cerebrovascular disease (CVD) in order to establish the standard criteria for transcranial basal cerebral arteries examination and settle normal velocimetric and hemodynamic parameters. TCD examination in patients suffering from CVD provides useful information for clinical management of such pathological conditions.
