[Analysis on data gathered from transcranial Doppler among 1500 normal adults community].
OBJECTIVE
To study the rates of receiving doppler signal, flow velocity of cerebral artery and the relationship between flow velocity,age and gender in normal adults in China.


METHODS
A total of 1500 normal residents at the community level in Guangdong province were examined, using transcranial doppler. Data was gathered and analyzed.


RESULTS
With the increase of age, the rate of receiving signal in cerebral artery gradually decreased. Difference between males and females was noticed. Mean velocity of cerebral artery decreased in both genders but the velocity was faster in females than in males and the pulsate index increased without difference.


CONCLUSIONS
The rates of receiving signal and the flow velocity of cerebral artery were related to age and gender and the findings from this study offered criterion for clinical transcranial doppler.
