Duplex sonography of the brain was performed on 130 pediatric patients: 53 with normal brains, 22 with intracranial hemorrhage, 15 with hypoxic-ischemic encephalopathy, 29 with hydrocephalus requiring ventricular shunting, and 11 with ventriculomegaly without hemorrhage or shunting. Doppler arterial waveforms from the Circle of Willis showed increased pulsatility in 82% of patients with intracranial hemorrhage, 53% of patients with hypoxic-ischemic change, and in only 31% of patients with hydrocephalus requiring shunt and 36% of patients with ventriculomegaly without shunt or hemorrhage. Mean pulsatility was increased (p less than 0.05) in all groups except ventriculomegaly without hemorrhage or shunt. No statistical difference was found in the diagnostic efficiency of three indices of pulsatility (frequency index profile, pulsatility index, systolic to diastolic ratio).
对130名儿科患者进行了脑部双功超声检查：53名脑部正常，22名有颅内出血，15名有缺氧缺血性脑病，29名有需要脑室分流的脑积水，11名有脑室扩大但无出血或分流。 Willis环的多普勒动脉波形显示，82%的颅内出血患者、53%的缺氧缺血性改变患者搏动性增加，而需要分流的脑积水患者中只有31%，无分流或出血的脑室扩大患者中只有36%搏动性增加。除无出血或分流的脑室扩大组外，所有组的平均搏动性均增加（p<0.05）。搏动性的三个指标（频率指数轮廓、搏动指数、收缩压与舒张压之比）的诊断效率无统计学差异。
