Further research is needed to determine whether other variables
of ultrasound exposure also have adverse effects on the developing fetus.
If you're seeking to
limit ultrasound exposure, just dial them way back (or stop doing them unless medically necessary) after the anatomy scan.
No association between the number of scans or duration
of ultrasound exposure and later autism spectrum disorder was found.
The new study
compared ultrasound exposure among three groups: 107 children diagnosed with autism spectrum disorder, 104 children diagnosed with a developmental delay, and 209 typically developing children.
They could then tune and adjust their ultrasound input instantly to stabilize the bubbles, excite them to open the barrier, and deliver a drug of a predefined dose, while maintaining
safe ultrasound exposure.
The widespread assumption of safety has led researchers in fetal behaviour to assure women volunteering for clinical trials that
ultrasound exposure of one to one - and - a-half hours (sometimes on more than one occasion) is safe for their unborn babies - yet we know of no follow - up of these exposed children.
Ultrasound exposure to mice might possibly be linked to hemorrhaging in the brain.
