Against entertainment ultrasound

Against entertainment ultrasoundDon't say you weren't warned. Over a year ago, I reported that the AMA was concerned about excessive fetal ultrasounds (If you want a picture, wait till the baby's born!)

Although there is no confirmed biological effect of ultrasound known today,there may be some effect identified in the future. For that reason ultrasoundshould be used only for medically indicated purposes.

That effect may now have been discovered. From Medgadget:

Recent research published in the Proceedings of the National Academy of Sciencessuggests that ultrasound could be damaging to [the] developing brain of a fetus.

The authors note that they are not recommending the discontinuation of fetal ultrasound for legitimate medical purposes. It's undoubtedly a useful tool.
