Description
Dongmei Zhang and co-authors present a 2026 cohort study testing ultrasound elasticity of the cervix to predict early birth. Cervical length alone predicts poorly in women without symptoms. The study enrolled 275 singleton pregnancies at one centre. Scans ran between weeks 18 and 24 of pregnancy.
Early birth before 37 weeks occurred in 37 women, or 13.5 percent of the cohort. A stiffness measure at the inner opening predicted best alone, with an AUC of 0.797 in their analysis. Combining length with an inner-to-outer strain ratio lifted the AUC to 0.828 overall. That pairing beat either measure alone and gave better decision value. Sensitivity was 73 percent and specificity 82 percent at the chosen cut-off. Outside validation is still needed.
