What is it?

A cervical scan is an ultrasound examination during which your cervix (the neck of your womb) is assessed and measured.

It’s important to measure the cervix during pregnancy as it can help identify if you’re at risk of having a premature delivery

A shorter measurement of your cervix may mean you’re more at risk of having your baby too early for survival.


Why would I need a cervical scan?

You may need a cervical scan if you’ve already experienced an early delivery, or if you’ve had a procedure performed on your cervix, such as laser surgery.

Having a cervix scan will help your midwife or obstetrician decide whether you should be considered for a cervical cerclage, or cervical stitch. This is inserted in you cervix at around 16 weeks gestation to help prevent the risk of miscarriage.

What happens during the cervical scan?

A cervical scan is performed internally for optimum accuracy. We measure the length of your cervix and look at the internal end of the cervix to assess for widening and see what happens when the cervix is put under pressure, for instance, when you cough.

We also combine the cervical scan with either a growth scan or welfare scan. This gives us the opportunity to check on the growth, health and wellbeing of your baby. These checks are performed conventionally through your tummy.
