The feasibility of studying ovarian arterial blood flow has been demonstrated, using an ultrasonic method combining real-time imaging and pulsed Doppler (the 'duplex' method). Results using a percutaneous full-bladder technique were validated by comparison with use of an ultrasound probe applied directly to the arteries at laparotomy. The ovarian arteries demonstrated qualitatively and quantitatively distinct flow patterns compared with the internal and external iliac arteries. From recorded waveforms a pulsatility index (PI) reflecting vascular impedance was calculated. The PI was found to be lower, indicating increased blood flow, in the artery supplying the ovary carrying the dominant follicle or corpus luteum. Serial studies suggest that this change occurs at an early stage of the menstrual cycle, possibly before the dominant follicle can be recognized by its size or increased hormone production. Uterine arterial flow was also detectable, more accurately abdominally than vaginally, and the changes typical of late pregnancy were already found to be present, though to a lesser degree, in the first trimester.
采用结合实时成像和脉冲多普勒的超声方法（“双功”法），已证实研究卵巢动脉血流的可行性。通过与剖腹手术时直接应用于动脉的超声探头进行比较，验证了经皮全膀胱技术的结果。与髂内动脉和髂外动脉相比，卵巢动脉在定性和定量上表现出不同的血流模式。根据记录的波形计算反映血管阻抗的搏动指数（PI）。发现携带优势卵泡或黄体的卵巢供血动脉的PI较低，表明血流量增加。系列研究表明，这种变化发生在月经周期的早期，可能在优势卵泡通过大小或激素分泌增加被识别之前。子宫动脉血流也可检测到，经腹部检测比经阴道更准确，并且已发现典型的晚期妊娠变化在孕早期就已出现，尽管程度较轻。
