【摘要】：目的使用动态电影序列研究正常年轻女性在不同月经周期子宫内膜蠕动的规律,同时观察和研究子宫内膜异位症患者排卵期的子宫内膜蠕动,并与正常年轻女性相对照。方法 2014年9月-12月期间,对55名年轻女性志愿者在月经不同周期进行盆腔动态磁共振扫描,采集时间为6min,并生成电影文件,以十倍速率播放。由两名影像科诊断医师进行观察记录子宫内膜蠕动的情况。结果子宫内膜蠕动在月经不同周期有着一定的规律,排卵期最为活跃,频率约12.48次/6min,主要蠕动方向为宫颈-宫底(CF);黄体期子宫内膜蠕动最不活跃,频率约为1次/6min,月经期内膜蠕动频率约为3.55次/6min,主要方向为宫底-宫颈(FC)。结论动态磁共振序列可以清楚显示子宫内膜蠕动征象。子宫内膜蠕动在不同月经周期有着一定的规律性,排卵期内膜蠕动最为活跃,主要方向为宫颈-宫底,有助于输送精子;黄体期内膜蠕动最不活跃,有助于胚胎着床和早期胚胎的保存;月经期内膜蠕动方向主要为宫底-宫颈,有助于向体外排出经血。
[Abstract]:Objective to study the rule of endometrial peristalsis in normal young women in different menstrual cycles and to observe and study the endometrial peristalsis in ovulatory stage of patients with endometriosis by dynamic film sequence, and to compare it with that of normal young women. Methods from September to December 2014, 55 young female volunteers underwent pelvic dynamic magnetic resonance scanning during different menstrual cycles. The acquisition time was 6 min, and the film files were generated and played at a rate of 10 times. The endometrial peristalsis was recorded by two imaging diagnostics. Results the endometrial peristalsis had certain regularity in different menstrual cycles, and the frequency of peristalsis was about 12.48 times / 6 min, and the main direction of peristalsis was cervico-uterine fundus CFS, while in luteal phase, endometrial peristalsis was the least active. The frequency of peristalsis was about 1 / 6 min and 3.55 times / 6 min respectively. Conclusion dynamic magnetic resonance imaging can clearly display endometrial peristalsis. Endometrial peristalsis has certain regularity in different menstrual cycle, the endometrial peristalsis is the most active in ovulation stage, the main direction is cervico-uterine floor, which is helpful to transport sperm, while in luteal phase, endometrial peristalsis is the least active. The peristalsis direction of endometrium in menstrual period is mainly fundus cervix, which is helpful to excrete meridian blood.
