Doppler studies of the uterine artery using an off-set Doppler transducer with a mechanical sector imaging transducer indicate clear changes in uterine perfusion during the ovarian cycle. In this study, 16 volunteers had Doppler studies performed at least twice weekly during spontaneous ovarian cycles. Endocrine assays were performed on each occasion to measure plasma oestradiol, progesterone and luteinizing hormone levels. Conventional criteria to assess uterine impedance using systolic/end diastolic ratio and Resistance Index were modified to obtain meaningful results and a new flow velocity wave form classification is presented. The results indicate increasing uterine perfusion with rising levels of plasma oestradiol and progesterone and a direct correlation with falling oestrogen levels in the follicular phase. We conclude that off-set mechanical sector duplex systems can be used effectively to monitor uterine responses to the hormone environment.
使用带有机械扇形成像探头的偏置多普勒探头对子宫动脉进行的多普勒研究表明，在卵巢周期中子宫灌注有明显变化。在本研究中，16名志愿者在自发卵巢周期中每周至少进行两次多普勒研究。每次都进行内分泌测定以测量血浆雌二醇、孕酮和促黄体生成素水平。修改了使用收缩期/舒张末期比值和阻力指数评估子宫阻抗的传统标准以获得有意义的结果，并提出了一种新的流速波形分类。结果表明，随着血浆雌二醇和孕酮水平的升高，子宫灌注增加，且在卵泡期与雌激素水平下降直接相关。我们得出结论，偏置机械扇形双功系统可有效地用于监测子宫对激素环境的反应。
