Cervical Length Screening
Cervix Ultrasound Scan (14-36 Weeks)
- Determine risk of premature or early delivery
- Ease of booking
- Instant peace of mind
If you are at risk of premature birth, it can be useful to determine the length of the cervix. A cervical ultrasound scan is typically carried out after an abdominal scan and can be administered at any stage from 14 weeks, although it is most useful when carried out sequentially at 17 and 21 weeks of pregnancy.
Cervical length should generally measure more than 25mm at 16-21 weeks. If your cervix measures less than 25mm you should discuss it with your midwife or obstetric consultant. Your Bodyvie sonographer might recommend a further follow-up cervical length screening in 2-3 weeks. In cases where the cervix is less than 25mm your medical specialist might suggest that you use progesterone or insert a cervical suture.
During your cervical scan, you will be provided with images and a medical report, which will allow your care team to advise you accordingly.
*Cervical length scans must be booked alongside a pregnancy scan.
