Abstract:
Objective:To explore the feasibility and influencing factors of E-cervix cervical elasticity analysis technology in analyzing normal cervical function during non pregnancy.Methods:213 women who underwent vaginal ultrasound examination in the Ultrasound Department of Foshan Maternal and Child Health Hospital from May 2019 to November 2019 were selected as the research objects. Taking the median sagittal section of the cervix as the initial section, the E-cervix technology software package was started to automatically obtain the elastic contrast index (ECI), hardness ratio (HR), cervical strain rate (IOS), cervical strain rate (EOS), cervical strain ratio (IOS/EOS) and cervical length (CL). The relationship among age, menstrual cycle, BMI index, birth history, delivery mode and elastic parameters were compared.Results:There was no correlation between the elastic parameters and age, and there was no significant difference among different age groups ( P>0.05); there was no significant difference in the elastic parameters of cervical tissue in menstrual period, proliferative period and secretory period ( P>0.05); there was no significant difference in the elastic parameters of underweight, normal and overweight ( P>0.05); CL was positively correlated with body mass index (BMI) ( r=0.225, P<0.05), there was no correlation between other parameters and BMI ( P>0.05); there was no significant difference between the elastic parameters of patients with and without birth history ( P>0.05); the CL of women with cesarean section [(34.22±4.96)mm] was higher than that of women with natural birth [(29.03±4.14)mm] ( P<0.05), and the other parameters had no statistical significance ( P>0.05). Conclusions:The elastic parameters of cervix obtained by E-cervix technique are not affected by age, BMI, menstrual period, reproductive history and delivery mode, and can be used for quantitative evaluation of cervical function.
