What is a 4d ultrasound?
A 4d ultrasound scan uses high-frequency sound waves to produce images of organs and tissues in the body and show the baby in the womb.
A 4d ultrasound will show an image like a 3d ultrasound but the images will move just like a video. In a 4d ultrasound, if you and the sonographer are lucky and catch the baby at the right time, you may see him or her sucking her thumb or opening and closing her eyes.
When should I have a 4d Ultrasound?
A 4d ultrasound is recommended at approximately 27-29 weeks, by this time the baby will have a bit more fat on them, making the 4d ultrasound clearer. An ultrasound will usually take between 20 and 45 minutes, depending on how easy the baby is showing up and if a clear image can be gained.
To prepare for a 4d ultrasound it is suggested you drink plenty of fluids, eat before your appointment and wear loose clothing.
Will an ultrasound scan harm my baby?
These types of ultrasound scans will not harm the baby, there have been many studies into this, and the findings were that they are in no way harmful to your unborn baby.
The sonographer will try and get the baby to move around so they can get a good, clear scan for you, they may suggest going for a walk, this is to wake the baby up so it cannot be asleep. They may suggest eating sweets or chocolate, this is said to stimulate the baby and make him or her more active.
Most ultrasound clinics will allow you to take images or a DVD home to cherish your memories forever.
