"At the first level it's a matter of someone being suspicious that something is going on," Watson said. The other, Watson said, are people who specialize in high-risk pregnancies and can use ultrasounds to diagnose, or even treat more and more genetic abnormalities.
One level is the standard obstetrician on the corner, who can do the basic measurements and tell you if your baby is growing normally and you end up with a picture on your fridge." Not Every Obstetrician is An Expert in Prenatal Imaging "You end up with two different kinds of people who do imaging. "What you can see in prenatal imaging is changing enormously," Watson said. Now, a portion of obstetricians have become experts in using prenatal imaging to diagnose genetic disorders an ultrasound wouldn't have caught a generation ago. "In some places the birth rates of these (genetic) problems have gone up."Īs ultrasounds for women seeking prenatal care have become almost universal in the United States and, as Evans argued, perhaps overly reassuring, doctors also say that the prenatal imaging has evolved into high tech and low tech uses.
"What has happened in the last 20 years is that many women are being falsely reassured by ultrasound and not going on to genetic testing," Evans said. Evans also thought that occasionally a false security in ultrasounds keeps prenatal genetic screening rates low, in addition to the high costs.
