Clinical application

Prediction of delivery at term

Sonographic measurement of cervical length is clinically useful in the prediction of time of delivery at term:

  • In women with planned cesarean section measurement of cervical length at 37 weeks can help in deciding whether to carry out the delivery at 37-38 weeks or delay this until 39-41 weeks.
  • In women undergoing induction of labor the pre-induction cervical length gives useful prediction of the induction-to-delivery interval and the likelihood of vaginal delivery and cesarean section.
