Ultrasound Safety

There is no evidence that ultrasound scans are harmful, if used according to the guidelines ultrasound scans have been used in pregnancy for decades. We ensure that when performing the 4D scans we will follow all the right guidelines to ensure that you and your baby are safe.

Having an ultrasound will not affect your baby. Ultrasound sends sound waves through your womb (uterus), which bounce off your baby's body. The echoes are turned into an image on a screen, so that you can see your baby’s position and movements. The frequency or length of the sound waves depends on how far along your pregnancy is and the type of scan being carried out.

Studies have found no link between ultrasound and birth weight, childhood cancers, dyslexia or hearing problems. 

Almost all women want a scan during pregnancy, so it's hard to find women who haven't had one make a comparison. That in itself may reassure you. 

During an ultrasound scan, the equipment generates a small amount of heat which is absorbed by the part of the body that's being scanned. Typical scans produce less than one degree C. This means they're fine for you and your baby. It's only if the temperature of the scanned body tissue rises by four degrees C that harm may be caused. 

We a low intensity of ultrasound spread over a large area, which causes very minimal heating. The fluid around your baby and any movements your baby make will help to spread any heat.
