Objective To examine the potential value of routine measurement of cervical length in
singleton pregnancies at 23 weeks of gestation in the prediction of the risk for early …

Background The role of the cervix in the pathogenesis of premature delivery is controversial.
In a prospective, multicenter study of pregnant women, we used vaginal ultrasonography to …

Different strategies have been developed to refine the prediction of the risk of preterm
delivery in asymptomatic patients. Transvaginal sonography has been used for this reason …

Objective: The aim of this study was to determine the value in the prediction of spontaneous
preterm delivery of ultrasonographically measured cervical length measured between 14 …

Objective To determine the accuracy of changes in transvaginal sonographic cervical length
over time in predicting preterm birth in women with singleton and twin gestations. Data …

Objective: To evaluate the accuracy of a single sonographic measurement of cervical length
early in the third trimester as a predictor of preterm delivery. Methods: A total of 771 women …

Objectives: We sought to determine the predictive accuracy for preterm delivery of
transvaginal ultrasonography of the cervix between 14 and 24 weeks' gestation in high-risk …

Objectives To evaluate the ability of combinations of cervical length and maternal history to
assess the risk of spontaneous preterm birth, and to provide a simple procedure for the …

Objective: To evaluate changes in cervical dimensions by transvaginal ultrasound in non-
randomly selected pregnant women. Methods: This longitudinal study included 154 …

The cervix has to open to allow vaginal birth. Ultrasound has now shown that this lower part
of the uterus begins to show changes weeks before eventual birth. Only transvaginal …
