This article discusses why doctors think that ultrasound is safe to use for fetal imaging.
Key points –
1. In 1992, the intensity of ultrasound was increased dramatically without any subsequent follow up research. Thus, modern assurances of safety are based on obsolete, inconclusive, and disorganized information.
2. The Output Display Standard are numbers on an ultrasound monitor that practitioners read to guestimate relative risks. It is not very accurate.
3. How safe a session is depends on the skill of the practitioner. Sonographers with more training are less likely to hold the ultrasound beam in one place for long, and maybe the really good ones will know important and delicate areas to keep it away from. In reality, many untrained personnel (nurses or lay-people) perform sonograms so this is not the case always.
Please be careful with the amount of ultrasound you expose your child to. Less is better, and we don’t know what it does yet.
