What are the normal reference values and age/sex variability for blood flow parameters in basal cerebral arteries measured by transcranial color Doppler sonography in healthy subjects?
Establishes that age and sex matching is a prerequisite for interpreting transcranial Doppler sonographic data due to significant age dependence of flow velocities.
Flow velocities in basal cerebral arteries range widely and are significantly age dependent. Age and sex matching of Doppler sonographic data is a prerequisite for clinically valuable conclusions.
Krejza et al. (Fri,) studied this question.
