【摘要】 应用Acuson-128彩色多普勒超声仪采用经腹法对26例妇女按月经周期的不同时间观察了卵泡发育及排卵前后的卵巢内血流显像及频谱变化,同时进行FSH、LH、P及雌二醇的放免测定。结果是,排卵前卵巢内动脉供血不丰富。频谱为低振幅高阻抗型;LH值呈上升趋势;排卵期75％出现舒张期血流;排卵后功能侧卵巢血流速度增高,频谱为高振幅低阻抗型,舒张期血流逐渐减慢或消失,孕酮值达到最高水平。因此彩色多普勒在卵巢内是否出现丰富舒张期供血,是判断功能性卵巢及排卵的可靠依据。更多还原

【Abstract】 By trans-abdomen method,blood flow display and its waveform changes of the ovaries in 26 women were observed with Acoson-128 color Doppler ultrasonic apparatus during different menstrual periods of follicular development cycle,preovulation and postovulation. At the same time,FSH,LH,P and estradiol level examined by RIA. The results were as follows:before ovulation,blood flow of ovarian arteries was not plentiful and its waveforms were high-impedance signals of low amplitude. LH level showed a go-up tendency. During ovulation,diastolic flow signal occurred in 75% cases. After ovulation,the blood flow in the functional ovary increased and its waveforms showed low-impedance signals of high amplitude. Diastolic flow decreased gradually or disappeared. P level was at its maximum. Therefore, whether there appeared plenty of diastolic flow from the ovary in the color Doppler display is a reliable evidence for judging functional ovary and ovulation.更多还原
