This is a scan that measures the length of the cervix.
It is an internal or transvaginal scan and is done after 16 weeks. The actual scan takes about 5 to 10 minutes however the appointment time is 20 minutes. The cervical length scan assesses the risk of a premature or early birth.
Preterm birth affects around approximately 1 in 10 births in England and Wales. The earlier a baby is born under 37 weeks the more chance there is of long term complications for the baby.
During this scan the heart beat of the baby will also be checked.
