回顾性分析了135例患者大脑中动脉（MCA）和大脑前动脉（ACA）的经颅多普勒研究。根据性别、血管、平均血流速度（MBFV）、收缩期血流速度（SBFV）、舒张期血流速度（DBFV）和样本体积深度（SVD）对3312个数据点进行分类。对每个深度的速度取平均值，并根据采集深度作图。男性MCA的MBFV和SVD之间的相关系数（r）为0.999。对于女性MCA，r = 0.986。对于ACA，男性，r = 0.911，女性，r = 0.894。所有其他数据显示r值大于或等于0.563，12个r值中有11个大于或等于0.808。这些数据表明，MCA和ACA的BFV以高度可预测的方式随SVD降低，由此可以在任何给定的SVD下估计预期的BFV值。(C)2000年世界医学和生物学超声联合会。
The baseline transcranial Doppler studies of the middle (MCA) and anterior cerebral (ACA) arteries of 135 patients were retrospectively reviewed. 3312 data points were classified according to gender, vessel, mean blood flow velocity (MBFV), systolic blood flow velocity (SBFV), diastolic blood flow velocity (DBFV) and sample volume depth (SVD). The how velocities at each depth were averaged, and plotted against acquisition depth. The male MCA yielded a correlation coefficient (r), between MBFV and SVD of 0.999. For the female MCA, r = 0.986. For the ACA, male, r = 0.911, and female, r = 0.894. All other data showed r values greater than or equal to 0.563, with 11 of 12 r values greater than or equal to 0.808. These data suggest that BFV reduces with SVD in a highly predictable way for the MCA and ACA, from which expected BFV values may be estimated at any given SVD.
