EmPA was unsuccessful in 9 patients (9/145, 6.21%) due to the interference of respiratory or intestinal movement and was successful in 136 patients (136/145, 93.79%), of whom 21 patients showed no EmP and 115 patients underwent EmPA and obtained quantitative results. The results of EmPA technique and naked eyes analysis about EmP intensity and transfer time had no significant consistence. Menstrual cycle, uterine position and history of induced abortion affected the quantitative results of EmPA.
EmPA technique provides noninvasive, quantitative and accurate detection and analysis of EmP in normal population and can evaluate EmP changes associated with menstrual cycle, uterine position and history of induced abortion.
Core Tip: Endometrial peristalsis analysis (EmPA) is the first automated and quantitative technique applied in the ultrasound system to detect and analyze endometrial peristalsis (EmP) features. In this study, EmPA technique was used to analyze EmP accurately and evaluate the changes of EmP associated with menstrual cycle and other factors such as uterine position and age.
