Could transabdominal or transvaginal scanning be unsafe for my baby?
Despite extensive studies over 30 years transabdominal and transvaginal ultrasound has not been shown to cause any harm to mother or baby. Indeed routine scanning of all pregnancies is now normal throughout the whole of Europe.
Could 3D or 4D scanning be unsafe for my baby? NO
In 3D and 4D scanning exactly the same type and intensity of ultrasound is used as with conventional scanning. In fact 3D scanning should reduce the exposure time, as by storing the data on a computer the baby's anatomy can be examined off line and not by continual scanning. 4D ultrasound, by showing movements, will be similar to a conventional scan in terms of exposure.
Further information on the safety of ultrasound is available from the BRITISH MEDICAL ULTRASOUND SOCIETY
