Ultrasounds have a good track record for safety.
It has been over 35 years since ultrasound was first used on pregnant women. Unlike X-rays, ionizing irradiation is not present and embryo toxic effects associated with such irradiation should not be relevant. “Studies continue to make sure ultrasound is safe. There is no reason to think that it harms mothers or babies,” according to the Society of Obstetricians and Gynaecologists of Canada.
Ultrasound does not use radiation.
All medical procedures have risk. But, there’s no evidence to show a prenatal ultrasound done properly will harm a mother or her unborn child. Done properly means it’s performed by a physician or a trained technician, called a sonographer. Ultrasound does not use radiation, as other procedures, such as X-rays, do.
An ultrasound is simply high frequency sound waves. There is no radiation being transmitted during ultrasound.
Are 3D and 4D Ultrasounds Safe?
“Like their traditional two-dimensional counterparts, 3D and 4D ultrasounds are considered safe, as long as they’re conducted by a certified professional based on medical recommendation. Parents shouldn’t get a 3D or 4D ultrasound to simply have a “better look” at their baby’s face,” says Michele Hakakha, M.D., an OB-GYN in Beverly Hills and author of Expecting 411. “They should also avoid commercial shops that offer “keepsake” 3D ultrasound images and videos.” —Parents.com
