Patient's question:
Does ultrasound have an effect on the fetus?Doctor's answer:
B-mode ultrasound is ultrasonic transmission, which does not involve ionizing radiation or electromagnetic radiation. It is a form of sound wave transmission, and these sound waves cause almost no harm to human tissues. Moreover, there have been no reports to date of fetal malformations caused by B-mode ultrasound examinations.2. Of course, although it is safe to have B-mode ultrasound during pregnancy, this does not mean that it can be done without time or frequency restrictions throughout the entire pregnancy. Research has shown that if the duration of the ultrasound examination exceeds 20 minutes, it may have irreversible adverse effects on the fetus. Therefore, it is recommended that expectant mothers do not undergo unnecessary ultrasound examinations throughout their pregnancy unless there are abnormal conditions.
