Using a special probe holder, cross-sectional area and time-averaged mean spatial velocity of the internal jugular vein were measured by means of a duplex scanner and multiplied to calculate volume flow. In a cohort of 100 subjects ages 21 to 70 years, average right plus left flow was 740 +/- 209 mL/min. Flow was 8.7% lower in females than in males. Normalization of flow to 100 g brain tissue by dividing it through the mean sex specific brain weight resulted in no significant sex difference. Within the age range investigated, there was no decrease of flow with age.
使用特殊的探头固定器，通过双功扫描仪测量颈内静脉的横截面积和时间平均空间平均速度，并将两者相乘来计算血流量。在100名年龄在21岁至70岁之间的受试者队列中，右颈内静脉和左颈内静脉的平均血流量为740±209毫升/分钟。女性的血流量比男性低8.7%。将血流量除以性别特异性脑平均重量，以将其归一化为每100克脑组织的血流量，结果显示无显著性别差异。在所研究的年龄范围内，血流量没有随年龄增长而下降。
