ContextAlthough shortened cervical length has been consistently associated with
spontaneous preterm birth, it is not known when in gestation this risk factor becomes …

Objective To determine whether short cervical length or internal os funneling before 20
weeks' gestation predicts early preterm birth or pregnancy loss in women with at least one …

Objective To determine whether high‐risk patients manifest cervical length< 25 mm on
transvaginal ultrasound before 14 weeks of gestation, and if this finding is predictive of …

Risk assessment for preterm delivery remains difficult, particularly among women with no
prior history of preterm birth. We hypothesized that accurate assessment of cervical length …

Objective: To describe the anatomic and technical difficulties encountered with transvaginal
ultrasound imaging of the cervix in a consecutive series of women at risk for preterm …

This review investigates the accuracy with which transvaginal cervical sonography predicts
spontaneous preterm birth. Published studies were identified without language restrictions …

OBJECTIVE: To estimate the risk of spontaneous preterm birth based on transvaginal
ultrasound cervical length and gestational age at which cervical length was measured …

Objective: Premature delivery is difficult to predict and causes considerable neonatal
morbidity and mortality. Despite much research, little progress has been made in timely …

Objectives To assess the role of cervical sonography and to compare various sonographic
cervical parameters in their ability to predict spontaneous preterm birth in high‐risk singleton …

Objective To examine the potential value of routine measurement of cervical length in
singleton low‐risk pregnancies at 37 weeks of gestation in the prediction of onset and …
