To determine the stiffness of the pregnant uterine cervix in vivo. was defined as the highest EP detected along the cervical canal. was 243 kPa (IQR, 67–422 kPa) for the early pregnant women and 5 kPa (IQR, 4–15 kPa) for those at term. In the early pregnant women the stiffness differed along the cervical length (p<0.05) whereas difference along the cervix was not found for late pregnant women. A positive correlation coefficient (Spearman’s rho) was established between the EPs of the uterus-near and the middle part (0.84), between the vaginal and the middle part (0.81), and between the uterus-near and the vaginal part (0.85).This new method can estimate the stiffness along the cervical canal in vivo. This method may be useful in the clinical...
