Objective To explore the clinical value of E-cervix elastography technology in assessing cervical maturity and predicting vaginal delivery Methods The 87 full-term pregnant women who gave birth in our hospital were selected and divided into spontaneous vaginal delivery group (61 cases) and the cesarean section group (26 cases) according to the delivery conditions. Transvaginal ultrasound examination, using E-cervix elastography technology to measure cervical elastic parameters, including stiffness ratio (HR), elastic contrast index (ECI), cervical internal and external oral strain values (IOS, EOS) and cervical internal and external oral strain ratio (IOS/ EOS). Bishop score and cervical length were measured. The differences of cervical parameters before and after contraction between the two groups were compared, and the receiver operating characteristic (ROC) curve was used to analyze the cut-off value of each parameter of the cervix in predicting vaginal delivery and its efficacy. Results The Bishop score，HR，IOS and EOS were statistically significant differences between the two groups（all P< 0.05）.However，there were no significant differences in CL，ECI and IOS/EOS between the two groups. Among them, 18 pregnant women were reassessed between the onset of regular contractions and cervical dilation. Only the spontaneous vaginal delivery group had statistically significant differences in HR, IOS, and EOS before and after regular contractions (all P<0.05). ROC curve results show that HR was the most sensitive in predicting vaginal delivery, with an AUC of 0.84 and a cut-off value of 51.94%, which is better than cervical length and Bishop score. Conclusion E-cervix elastography technology may objectively，conveniently and accurately show the changes of the cervix in full-term of pregnancy，and can be used as a valuable tool to evaluate cervical maturation.
