Pregnant women should have the lowest number of ultrasounds

Long-lasting ultrasound waves in the mouse fetus' brain disrupt a process of neuronal shift, according to a team at Yale University in Connecticut, USA.

Dr. Pasko Rakic ​​said: 'The special shift of nerve cells during development is important for the normal development of the cerebral cortex and its function'.

Writing in the Methodology of the National Academy of Sciences , Rakic's group said aerial discovery means that human fetal ultrasound is dangerous, but doctors and pregnant women should have a low number of ultrasounds. Best.

Ultrasound helps parents see their unborn child and doctors have the opportunity to detect fetal defects for timely treatment. However, many studies suggest that ultrasound can affect fetal brain development.
