Is fasting required for 4D color Doppler ultrasound examination?

When you go to the hospital for some examinations, the doctor should tell you in advance what you should pay attention to. When the doctor tells you what you should pay attention to, you must listen carefully, and adopt it during a routine physical examination. This is related to whether the results of the examination are true, so you must be careful. The following web editor will help you to see, do you need to be on an empty stomach for 4D color Doppler ultrasound?

Do I need to fast for 4D color Doppler ultrasound?

1. The four-dimensional color ultrasound examination does not require fasting and does not require special preparation. However, pregnant mothers who want to have an ultrasound examination must choose a reliable hospital to ensure the accuracy of the test results.

2. The four-dimensional color ultrasound examination has excellent imaging effect. Compared with the general B-ultrasound in the past, the imaging effect of the four-dimensional color ultrasound is clearer and more accurate, and can solve the problems existing in the growth and development of the fetus in time. In addition, the four-dimensional color ultrasound examination is intuitive and dynamic. Pregnant mothers can see all the dynamics of the fetus's face in the uterus during the four-dimensional color ultrasound examination, such as the baby's yawning, smiling, etc., which adds fun to the prenatal examination process.

3. In addition, in terms of preparation for the four-dimensional color ultrasound, one difference between the four-dimensional color ultrasound and the general B-ultrasound examination is that before the examination, there is generally no need to prepare to hold urine. As long as the woman goes to a reliable hospital for examination during the four-dimensional color ultrasound examination period, fetal malformation examination and other examinations can be performed.

When is the best time to do 4D color Doppler ultrasound?

1. Four-dimensional color ultrasound can be performed at any week of pregnancy, but it should be noted that there are currently objections to doing four-dimensional color ultrasound during early pregnancy (before 12 weeks of pregnancy). For safety reasons, it is recommended to do fetal four-dimensional color ultrasound after 16 weeks of pregnancy.

2. The best time to take a four-dimensional color Doppler ultrasound is during the 24th to 28th week of pregnancy, because the body and key internal organs of the fetus have already grown and developed after the 16th week of pregnancy. The amniotic fluid flow during the 24th to 28th week of pregnancy is more suitable for fetal malformation screening. The 24th week of pregnancy is the stage of rapid brain development. The fetal structure has been formed at this stage, the size of the fetus and the amniotic fluid are moderate, the activity space in the uterine cavity is large, the echo effect of the fetal bones is relatively small, and the image is clearer.

3. In addition, four-dimensional color ultrasound not only has all the functions of three-dimensional color ultrasound, but also adds time dimension parameters on the basis of three-dimensional color ultrasound images, so as to observe the dynamic movement images of the fetus in real time. Pregnant mothers can choose three-dimensional color ultrasound or four-dimensional color ultrasound according to their own conditions.
