During a healthy pregnancy, going for an ultrasound can be a pretty thrilling experience. It?s a chance to see your baby?s profile, wee little feet and, if you desire, whether you?re carrying a boy or a girl. Some parents, however, wonder if all that checking in on babe is safe.
The good news is that ultrasounds, which have been around for 30 years, have a good track record for safety. ?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.
Do ultrasounds use radiation"
Ultrasounds?sometimes referred to as sonograms, although that’s technically the name of the picture produced?don?t use radiation but rather they use sound waves that are too high-pitched to be heard by the human ear. The technician holds a scanning device called a transducer, which focuses these waves on different parts of your belly. The sound waves bounce back from organs inside your body, and the transducer picks up the sound waves, which then form an image that can be seen on the monitor. (Hello, baby!) Ken Lim, the division head of Maternal Fetal Medicine in Obstetrics and Gynaecology at BC Women?s Hospital, says there?s no evidence that the baby can feel or hear the sound waves as the frequency is above the audible range.
