Ultrasound imaging is the most widely
used medical imaging method during pregnancy. Fetal ultrasound imaging provides
real-time images of the fetus. Doppler fetal ultrasound heartbeat monitors are
hand-held ultrasound devices that let you listen to the heartbeat of the fetus.
Both are prescription devices designed to be used by trained health care
professionals.
The FDA discourages fetal imaging for keepsake videos and other
non-medical purposes. The FDA is
concerned about over-the-counter sale of prescription fetal ultrasound
heartbeat monitors (also called doptones).
These devices, when used by untrained persons, could expose the fetus to
prolonged and unsafe energy levels or could provide information that is
interpreted incorrectly.
