About 4D Ultrasound Scans
It is very common these days for expecting parents to have 4D ultrasound scans or bonding scans as otherwise known. 3D/4D ultrasound is an ultrasound scanning technique, often used during pregnancy providing 3D/4D images of the baby.
There are several different ultrasound scanning techniques in pregnancyultrasound. The standard common diagnostic scan is the 2D ultrasound scan. In 3D baby scanning, however, instead of the sound being sent straight down and reflected back, it is sent at different angles. The returning echoes are processed by a powerfull computer program resulting in a 3D volume image of the baby's surface and/or internal organs.
Clinical use of this technology is an area of intense research activity especially in fetal anomaly scanning but there are also popular uses that have been shown to improve fetal-maternal bonding. 4D baby ultrasound scans are similar to 3D scans, with the difference associated with time.
So 4D ultrasound scans are essentially 2D ultrasound scans and the scanner puts the 2D information together to create a 4D image of the baby.
The ideal time to have a 3D/4D ultrasound scan is between 26 and 30 weeks of pregnancy as the baby sking is better devoloped to see the face.
This 4D ultrasound scan incudes:
- 2x b/w 3D images in mounted card frame
- 1x colour 3D image download to Ipod/Mobile
- Growth report, includes estimated weight of baby at current gestation
- Wellbeing assessment includes position of baby and placental position
- Complimentary gender confirmed if requested
- 30 minute appointment
No preparation for this scan is neccesary but we reommend that during the week before your 4D scan, you drink a couple of extra glasses of water each day. This will help you to be hydrated, and assures that there is sufficient amniotic fluid around your baby which helps with the 4D scan. A full bladder is not required.
From experiences we know that sometimes chocolates, sweets, fresh orange or even fizzy drinks can help when trying to stimulate your baby to move, so feel free to bring some along to your appointment in case the baby is having a nap. Caffeine is not recommend before your 4D scan.
When you arrive have a little walk around, this might help wake your baby up before for the scan.
The Pregnancy Ultrasound Scan
Pregnancy or baby ultrasound scans are very common part of prenatal care. This is because ultrasound scans are completely painless, have no known side effects on mothers or babies, and can be carried out at any stage of pregnancy: in early pregnancy, ultrasound is being used to confirm the baby's heartbeat and exclude any early stage abnormalities; later in pregnancy ultrasound is being used to evaluate the baby's oveall health.
Diagnostic Medical ultrasound scan or medical sonography as otherwise known is a painless imaging technique utilising sound waves to produce internal images of the body.
It is called ultrasound as the sound frequency being used is at the region of 1 to 20MHz. The human ear cant can’t hear these frequencies.
The sound waves are produced by the transducer or the probe as most commonly known. As they travel through the body they bounce back to the transducer due to various differences in tissues. The returning echoes are picked up by the probe and a powerful computer analyses the echoes and creates the image on the screen.
There are various kinds of ultrasound scans that can be performed and each looks at different organs of the body such as tendons, muscles, joints, blood vessels, liver, kidneys, uterus and ovaries to confirm or exclude possible pathology.
Unlike Ct and MRI, ultrasound does not use radiation and therefore is pregnancy friendly. It is also live and is ideal for musculo-skeletal exams to evaluate moving joints.
All our scans include a basic wellbeing check of the baby.
Should your baby be in a poor position to obtain clear 4D video images the sonographer will first try a few techniques to obtain the best image. If these are unsuccessful you may be asked to return our Patient Lounge and walk around in an effort to encourage your baby to move. We may try to re-scan you several times during clinic opening hours. If there isn't available time in the schedule or if the clinic is closing we will ask you to re-book for another day. You will not be charged for additional scanning time on your second visit. If your 4D video scan is successful on the second attempt the cost to you will be the same if your 4D baby scan were completed on the first appointment.
Although we will do a basic wellbeing check of the baby we will not produce a report for you to take away. This is because this ultrasound scan is mostly concentrated to the 4D nature of the examination.
