Routine fetal ultrasounds are considered safe for both mother and baby. Researchers haven't noted any adverse effects of fetal ultrasounds in children followed for several years after birth.

Still, caution remains important. The use of fetal ultrasound solely to create keepsakes isn't recommended.

Fetal ultrasound also has limitations. Fetal ultrasound might not detect all birth defects — or might incorrectly suggest a birth defect is present when it's not.
