We are pleased to announce extended opening times for Alderley Edge.

Cervical Scans (14-36 Weeks)

  • We offer morning, evening and weekend appointments.
  • A Cervical Scan can help determine whether you are at risk of premature or early delivery.


If you are at risk of premature birth, it may be useful to have a scan to assess the length of the uterine cervix. A cervical scan is usually done after an abdominal scan. This can be done at any stage from 16 weeks but is most useful if done sequentially at 17 and 21 weeks of pregnancy.

How is this scan done?

A transvaginal approach is the clearest way to best visualize the cervix.

When is this scan done?

The scan can be done at any stage from 16 weeks but is most useful if done sequentially at 17 and 21 weeks of pregnancy.

What result can I expect?

In general a cervix should measure more than 25mm at 16-21 weeks. If the cervix measures less than 25mm you should discuss it with the person looking after your pregnancy. We may recommend a further cervical scan in 2-3 weeks. If the cervix is less than 25mm there may be options to use progesterone or insert a cervical suture.

What are the indications or reasons for having this scan?

  • Previous premature delivery
  • Loss of amniotic fluid
  • Previous cervical surgical procedures
