Pregnant mothers often ask:
Doctor, I have done many B ultrasounds in 10 weeks of pregnancy now, will this have a bad impact on the baby? Will there be too much radiation on the ultrasound?
Such questions are often asked by pregnant mothers, which is also the most concerned question for everyone, so let the medical imaging doctor answer in detail whether the B ultrasound examination is safe or not?
B ultrasound examination of "ultra", refers to ultrasonic, the human ear can not hear the high-frequency sound waves, medical ultrasonic examination of the working principle, that is, ultrasonic emission into the human body, when it encounters the interface will be reflected and refracted, and may be absorbed and attenuated in human tissues, the ultrasonic output power emitted by the probe is very small and the ultrasonic examination dose does not have an additive effect, so if the clinician needs, even if the examination several times will not cause harm to the fetus and the mother. Pregnant mothers should not mistakenly think that ultrasound, like X-rays or CT, relies on radiation for imaging, they are two completely different test methods, and ultrasound is not a substitute for other tests.
According to medical imaging doctors, so far, there is no evidence to prove that ultrasound has radiation to the fetus, and there are no reports of embryonic death or fetal malformations due to ultrasound; on the contrary, there are more and more reports of ultrasound diagnosing various deformities and developmental abnormalities, so for the safety of babies and mothers, give ultrasound a trust, we are also very responsible.
