Extensive studies over 30 years have found that ultrasound has not been shown to cause any harm to mother or baby. Routine scanning of all pregnancies is now normal throughout the U.K.
In 3D/4D scanning exactly the same type and intensity of ultrasound is used as with conventional 2D scanning. 3D and 4D Ultrasound both utilize sound waves to look inside the body.
At Hello You all scans are performed by experienced NHS trained clinicians – either midwives or radiographers, trained to a minimum of PgC in Medical Ultrasound.
