By Mayo Clinic staffRoutine fetal ultrasounds are considered safe for both mother and baby. Improper use of fetal ultrasound, however, can't be considered entirely risk-free. Although researchers haven't noted any adverse effects of fetal ultrasound on children followed for several years after birth, caution remains important.
Fetal ultrasound also has limitations. Fetal ultrasound may not detect all birth defects — or may incorrectly suggest a birth defect is present when it's not.
