Abstract To investigate the predictive value of the parameters of elastography of cervix (E-cervix) of pregnant women for their cervical sensitivity, and to study the correlation between these parameters of the women and their cervical dilation time during active stage of labor. Methods: 124 full-term pregnant women with singleton who were hospitalized for induce labor from May 2021 to January 2022 were analyzed retrospectively. These women were divided into group A (66 women with sensitive cervix for dilation) and group B (58 women without sensitive cervix for dilation) according to the time of uterine orifice dilation during labor induction. The elastic imaging parameters of the women in the two groups at 12h before labor induction were evaluated by E-cervix technique and the Bioshop score of the women in the two groups was also evaluated. Receiver operating characteristic (ROC) curve was drawn to analyze the predictive values of ECervix parameters and Bioshop score for the cervical sensitivity. The cervical dilation time of the women was compared between the two groups. Pearson correlation coefficient was used to analyze the correlation between the cervical dilation time of the women and their E-Cervix parameters. Results: The Bishop score (3.26±0.56 points) of the women in group A was significantly lower than that (3.89±0.87 points) of the women in group B, and the values of E-Cervix elastic imaging parameters of the women in group A were significantly higher than those of the women in group B (all P＜0.05). ROC curve analysis showed that the area under the curve (0.869) of E-Cervix parameters for evaluating the cervical sensitivity was significantly higher than that (0.746) of the Bishop score. The sensitivity and the specificity of E-Cervix parameters for evaluating the cervical sensitivity were 87.4% and 82.7%. The cervical dilation time (190.0±58.6min) of the women in group A was significantly shorter than that (226.8±57.6min) of the women in group B (all P＜0.05). Pearson correlation analysis showed that the cervical dilation time of the women was positively correlated with their E-Cervix parameters (P＜0.05). Conclusion: E-Cervix can effectively predict the cervical sensitivity of the pregnant women, and the parameters of E-Cervix are positively correlated with the cervical dilation time.
