A 3D/4D ultrasound scan can be performed in order to see a preview of the baby from 26 to 32 weeks of pregnancy.
A 4D scan is a 3D scan with the added dimension of time – as in a film or video – so the baby can be seen to be moving. 4D scans are not usually needed for medical reasons.
If the baby has a rare malformation, a 3D or 4D scan could provide extra information for medical purposes, but this is rare.
Parents may want the scan if they are curious to see their baby's face. If you have a 3D or 4D scan, we always do a wellbeing scan first, before trying to view the face or other parts of the body in 4D. It may take some time to get a good view of the baby, so the scan could take 30-60 minutes.
If the baby is not in a favourable position you may be asked to go for a walk and return later. The best time to do a 4D scan is at 26-32 weeks of pregnancy when there is a greater volume of amniotic fluid but when the baby has not yet become too big. It is more difficult to see the face if the baby has its arms or legs in front of the face. The baby can be seen to be moving. Sometimes it is possible to record your baby yawning or stretching.
A 3D/4D scan is ideally is performed between 26 – 32 weeks of pregnancy.
3D / 4D scans are most often done to satisfy curiosity of the family. There is no danger in doing them although it is better that they are not prolonged or repeated excessively.
The sonographer is the best and most qualified person to do this scan.
We offer morning, afternoon and evening availability during the week, as well as weekend appointments. A surcharge will be applied for evening and weekend appointments. We have a wide range of availability therefore same day appointments can be easily arranged. Our Sonographers are here to reassure even at short notice.
Yes. The baby needs to be co-operative. This may take up to 45 minutes. If the mother is overweight it may be particularly difficult. We may ask you to take a short walk and a sweetened drink to get the baby to move. Rarely we may need you to come back on another day. If the placenta is at the front this can also causes problems in getting good pictures.
We provide still ultrasound images for you to take away with you on the day. We also send these to you electronically, with a couple of video clips. We also provide a USB stick with the full 3D/4D experience.
A Wellbeing/Growth scan can be done anytime between 23 - 40 weeks.
For cancellations, a full refund of your appointment fee will be given with 24 hours notice. If less than 24 hours notice of cancellation is given, a £50 cancellation fee will be applied. Our full terms and conditions can be found here: Terms and Conditions
Some early pregnancy ultrasound scans are performed using a transvaginal probe technique. This technique is used to view the pelvic anatomy optimally, as the ultrasound probe can transmit safe ultrasound waves more directly to the pelvic area. In later stages of pregnancy, it may be advised to perform a transvaginal ultrasound scan to have a closer look at a baby’s anatomy, or to assess the maternal cervix.
There is no clinical risk associated with performing a transvaginal ultrasound scan. Transvaginal ultrasound scans can safely be performed during episodes of vaginal bleeding.
It is important that you understand the procedure that is associated with this examination.
Below is a link to our Transvaginal Ultrasound Consent Form. This must be completed ahead of your appointment to confirm whether you consent or do not consent to having your scan performed transvaginally.
