4D ultrasounds are considered safe during pregnancy by most medical experts. The technology is not new and uses the same sound waves as 2D ultrasounds. There is no risk of radiation-related cancer or tissue damage, and any temperature changes are monitored by ultrasound technicians. It is recommended to limit ultrasounds to necessary procedures.
Most medical experts agree that 4D ultrasounds are safe for use during pregnancy. These ultrasounds allow parents and medical staff to capture images of a developing baby in 3D and witness the movements at the same time, which is why it is called 4D. Parents and medical staff can view the baby and her movements in real time on a computer monitor. Some people have expressed concern that the sound waves used in 4D ultrasound can raise tissue temperature. Many medical experts say, however, that the potential temperature change isn’t significant enough to cause harm.
Much of the concern some people have about the safety of 4D ultrasound may stem from the fact that they view it as a new technology. The fact is, however, that 4D ultrasounds use technology used in regular 2D ultrasounds that have been around for years. Pregnant women often have such ultrasounds on a routine basis, with no harm to their unborn babies. A 4D ultrasound works the same way as a 2D ultrasound. The difference is that 4D ultrasounds use more technologically advanced scanners that allow you to see more of a woman’s uterus and her developing baby.
A person may be more concerned about the safety of a 4D ultrasound if they identify it with X-rays and similar diagnostic tests. Unlike X-rays, however, 4D ultrasound does not involve the use of radiation. This means there is no risk of radiation-related cancer or tissue damage from 4D ultrasound.
Some people cite the temperature rise that sound waves can cause as they pass through tissue as a reason to be concerned about using 4D ultrasound. Most medical experts, however, say the risk is too small to warrant concern or avoidance of ultrasounds. Also, ultrasound technicians typically monitor changes in temperature during the ultrasound, so any worrisome changes can be detected, and the ultrasound can then be stopped.
If an ultrasound procedure has caused a dramatic increase in the temperature of fetal tissues, it is possible that this could harm a developing baby. It’s extremely unlikely, however, that temperatures could ever rise that much during a regular 4D ultrasound. As such, most medical experts consider it safe. If a woman has concerns about her safety, however, she may find her doctor a good source of information about the procedure. Additionally, many in the medical field recommend limiting ultrasounds to those that are necessary rather than using them as elective procedures.
