Non-diagnostic ultrasound has demonstrated biological effects such as cell heating or thermal effects and cavitational activities using plants and animals. These experiments have had various outcomes and are difficult to equate with human outcomes. Also, diagnostic ultrasound uses far lower intensities. The current epidemiologic data finds no adverse outcomes from ultrasound use. Many researchers believe that the benefits of diagnostic ultrasound outweigh the risks. Human studies have not documented negative outcomes except for one study which shoed increased fetal activity for the majority of exposed babies when scanned with the Doppler.
