Regarding the question of which is better, system ultrasound or four-dimensional ultrasound, relevant personnel indicate that the examination scope of the four-dimensional ultrasound is relatively comprehensive, and the growth and development of the baby’s body can be observed significantly. The choice between four-dimensional and system color Doppler ultrasound should be based on individual conditions. Then, let’s have a simple understanding and understanding of this question, hoping that the following points will be helpful to everyone!

Which is better, system ultrasound or four-dimensional ultrasound

The examination scope of the four-dimensional color Doppler ultrasound is relatively comprehensive, and the growth and development of the baby’s body can be observed significantly.

In fact, the choice between four-dimensional and system color Doppler ultrasound should be based on individual conditions. Of course, there are also package options available for pregnant women visiting the hospital, where both projects can be examined together. It is very important to note that both four-dimensional and system color Doppler ultrasounds have the best examination time, with system color Doppler ultrasound recommended between 23-25 weeks of pregnancy, and four-dimensional ultrasound between 25-28 weeks.

How to do a four-dimensional color Doppler ultrasound

Ultrasound uses a four-dimensional color Doppler ultrasound instrument for examination, which can immediately obtain the three-dimensional image of the fetus and is an excellent examination method. The four-dimensional color Doppler ultrasound instrument has an excellent ergonomic design and is a device made using the principle of ultrasound, without radiation sources such as X-rays, microwaves, and radio waves, which have no impact on physical health.

Due to the small damage to the human body caused by four-dimensional color Doppler ultrasound diagnosis, it can be re-examined, and the diagnosis is fast and accurate, so it has become the preferred imaging diagnostic method in obstetrics and gynecology, providing a reliable basis for diagnosis and research, and has become an indispensable auxiliary diagnostic tool. Ultrasound is a sound wave without radiation, and it only briefly passes through the body, having no adverse effects on the pregnant woman and the fetus.

Common Questions:

1. There is no need to hold urine or fast for a four-dimensional color Doppler ultrasound examination. The pregnant woman only needs to come to the hospital for examination within the required time.

2. Before the four-dimensional color Doppler ultrasound examination, it is best for the pregnant woman to separate her top and denim pants. During the examination, the doctor mainly conducts an examination based on the examination equipment, including the current facial growth and development of the fetus, as well as the presence of any developmental defects in the heart, brain, and spine. If there are signs of malformation detected during the examination, the examination time may be relatively longer.

3. Due to the technical limitations of ultrasound technology, it is not possible to detect all malformed fetuses, so the accuracy of ultrasound diagnosis cannot reach 100%.

4. Soft tissues such as the inside of the ears, gender, reproductive organs, and the palate are not within the scope of color Doppler ultrasound examination for the fetus.

5. The examination of the baby’s limbs does not include the number of phalanges and toes, and only 50%-60% of congenital heart diseases can be detected by the four-chamber heart examination.
