WASHINGTON - Exposure to ultrasound can affect fetal brain development, a new study suggests. But researchers say the findings, in mice, should not discourage pregnant women from having ultrasound scans for medical reasons.

When pregnant mice were exposed to ultrasound, a small number of nerve cells in the developing brains of their fetuses failed to extend correctly in the cerebral cortex.

"Our study in mice does not mean that use of ultrasound on human fetuses for appropriate diagnostic and medical purposes should be abandoned," said lead researcher Pasko Rakic, chairman of the neurobiology department at Yale University School of Medicine.

However, he added in a telephone interview, women should avoid unnecessary ultrasound scans until more research has been done.

Dr. Joshua Copel, president-elect of the American Institute of Ultrasound Medicine, said his organization tries to discourage "entertainment" ultrasound, but considers sonograms important when there is a medical benefit.

"Anytime we're doing an ultrasound we have to think of risk versus benefit. What clinical question are we trying to answer," Copel said in a telephone interview. "It may be very important to know the exact dating of pregnancy, it's certainly helpful to know the anatomy of the fetus, but we shouldn't be holding a transducer on mom's abdomen for hours and hours and hours."

Rakic's paper said that while the effects of ultrasound in human brain development are not yet known, there are disorders thought to be the result of misplacement of brain cells during their development.

"These disorders range from mental retardation and childhood epilepsy to developmental dyslexia, autism spectrum disorders and schizophrenia," the researchers said.

This is scary, dam-n

This is scarrier than hell!

I can't believe that they just found this out!!!!!!!!

Insanity plain and simple, lol.

in 5 years they will probably have a study proving this all wrong. I hardly jump to conclusions anymore about any of these so called studies. Years ago they were telling people to not eat eggs cause of colesterol concerns... now they say don't worry about it. Go figure.

Technically breathing is hazardous to our health. Think of all the air polution.
