Cervical Volume and Prediction of Preterm Labor

Role of Cervical Volume and 3 D Power Doppler Indices for Prediction of Preterm Labour

The primary aim of this research is to assess the predictive value of 3D cervical volume and 3D power Doppler indices in predicting pregnancies at risk of preterm labor.

Secondary aim: to compare 2D cervical length and 3D cervical length in coronal view for predicting preterm labour.
