Determinations of blood velocity in vessels of cerebral cortex have been done using a 20 MHz impulse Doppler unit. In comparison we registered the blood flow pulsation curves at the anterior cerebral artery with aid of a 5 MHz-cw-Doppler system. The peripheral resistance index was calculated and it could be proved a strong correlation between the results of the anterior cerebral artery and the vessels of cerebral cortex. Another study showed that the results of the method could be reproduced. The problem of the impulse Doppler examinations of cerebral cortical vessels is the fact, that the exact topography of the vessels examined cannot be defined exactly.
已使用20兆赫脉冲多普勒装置测定了大脑皮质血管中的血流速度。作为对比，我们借助5兆赫连续波多普勒系统记录了大脑前动脉的血流搏动曲线。计算了外周阻力指数，结果表明大脑前动脉与大脑皮质血管的测定结果之间存在很强的相关性。另一项研究表明该方法的结果可以重现。大脑皮质血管脉冲多普勒检查的问题在于，无法精确确定所检查血管的准确位置。
