The AIUM recommends that appropriately trained and credentialed medical professionals who have received specialized training in fetal imaging perform all fetal ultrasound examinations. The use of ultrasound without a medical indication to view the fetus, obtain images of the fetus, or identify the fetal external genitalia is inappropriate and contrary to responsible medical practice. The American Institute of Ultrasound in Medicine (AIUM) advocates the responsible use of diagnostic ultrasound and strongly discourages the nonmedical use of ultrasound. Therefore, prudent use and safety of diagnostic ultrasound in pregnancy should involve a conservative approach that obtains necessary diagnostic information at minimal exposure. In addition, the absence of conclusive studies demonstrating causal relationships does not constitute proof that adverse effects are impossible. The epidemiologic evidence is based primarily on exposure conditions before 1992, the year in which acoustic limits of ultrasound machines were substantially increased for fetal/obstetric applications. Other studies have not demonstrated such effects. Some studies have reported effects of exposure to diagnostic ultrasound during pregnancy, such as low birth weight, delayed speech, dyslexia, and non–right-handedness. Based on the epidemiologic data available and on current knowledge of interactive mechanisms, there is insufficient justification to warrant conclusion of a causal relationship between diagnostic ultrasound and recognized adverse effects in humans.
