The text in one post sharing the claim (here) reads, “A Single Exposure to Ultrasound Causes DNA Damage Similar to 250 Chest X-Rays” overlayed on an ultrasound image of a fetus. A URL printed across the fetus image leads to an article (here) that makes unfounded claims about the risk of fetal ultrasound, and cites a 1981 study for the “250 chest x-rays” figure. The 1981 study did not draw any such conclusion. In response to a request for comment, the author of the article Jeanice Barcelo said she stands by her claim about the 1981 study. A 1981 study of mouse cells in test tubes did not conclude that ultrasound caused DNA damage equivalent to that of hundreds of x-rays, and extensive research finds ultrasound to be safe for use during pregnancy.
