应用超声指标评估子宫内膜容受性研究进展

Research progress of application of ultrasound indicator in evaluating endometrial receptivity

目前,子宫内膜容受性(ER)评估是不孕症诊断治疗中的常规方向,已经成为临床上亟待解决的关键问题。ER的定义即子宫内膜接受胚胎的能力,从而引出了植入时间窗的概念。超声指标评价ER具有简单、安全、无创和可重复的优点,越来越被妇产科医生所重视,已经成为生殖医学上研究ER最广泛的影像学方法。为此,就超声形态学指标、血流有关指标、子宫收缩及子宫内膜蠕动波、子宫内膜造影四个方面对应用超声指标评估ER研究进展进行综述。

At present,the evaluation of endometrial receptivity(ER)is a routine research direction in the diagnosis and treatment of infertility,and it has been an key problem that have to be settled urgently in clinical practice.The definition of ER is the ability that endometrium receives embryo implantation,thereby the concept of implantation time windows was proposed.Ultrasound was applied to evaluate ER has series advantages included of convenience,safety,non-invasive and repeatability.Therefore,gynecologists has pay more and more attention to it and it has been the most extensive imaging method in reproductive medicine for studying of ER.This paper through applied ultrasound indicators to review the research progress of evaluating ER from four aspects included morphological index,relative index of blood flow,uterine contraction and endometrial peristaltic wave and endometrial angiography.
