Combination of cervical sonoelastography with cervical length measurement and fetal fibronectin to improve prediction of preterm birth

Purpose: Measurement of cervical length and the cervicovaginal fetal fibronectin test (fFN) are routinely used to assess the risk of preterm birth. Cervical sonoelastography permits quantitative assessment of elasticity of the cervical tissue. It was successfully used to detect focal pathologies of the cervix and to determine effective induction of labor. The aim of the study was to improve the prediction of spontaneous preterm birth by combining cervical sonoelastography with cervical length measurement and fetal fibronectin (fFN). Material and methods: We designed a prospective study including patients with pr…
