Cervical Length Scan
Transvaginal measurement of the cervix — the most reliable predictor of preterm birth risk.
01 · What Is This Scan
Screening For Preterm Birth Risk.
A short cervix is the single strongest predictor of preterm birth. Cervical length is measured accurately via a brief transvaginal scan, ideally at the time of the anomaly scan or when preterm risk is a concern.
02 · Why It Matters
- Preterm birth is a leading cause of neonatal complications
- Identifies women who benefit from progesterone or cerclage
- Recommended for women with prior preterm birth or LEEP

A Note From Dr. Archana
"Two extra minutes at the 20-week scan can prevent months of NICU care. We measure the cervix routinely for every anomaly scan patient."
