Can 3D color Doppler ultrasound detect deformities?

Pregnant women need to do 3D color ultrasound during pregnancy. There are some differences between 3D color ultrasound and 4D color ultrasound. Compared with 4D color ultrasound, 3D color ultrasound is not as clear as 4D color ultrasound, but it can also show the development of the fetus better than ordinary color ultrasound. Many people even use 3D color ultrasound to check whether the fetus in the body is deformed. So can 3D color ultrasound rule out deformities?

Three-dimensional color ultrasound can completely rule out abnormalities. Three-dimensional color ultrasound has the following examination functions:

1. Early pregnancy

It can display the complete gestational sac and see through the embryo that is beginning to take human form.

2. Second trimester

The second trimester is from 24 to 32 weeks of pregnancy. During this period, the various organs of the fetus can be clearly displayed, the growth and development of the fetus can be understood, and the gross structure of the head, limbs and organs can be observed for deformities. Because the fetus is fully developed and the amount of amniotic fluid increases at this stage, three-dimensional imaging is more effective under liquid surrounding conditions, and can display most tissue and organ structures and the entire fetal development status. The fetus at this stage has a plump face and clear facial features. This is the best period for diagnosis, with a high imaging success rate and is most meaningful for clinical diagnosis.

2. Late pregnancy

It can accurately determine the fetal position, check the maturity of the placenta, whether the umbilical cord is wrapped around the neck, measure the umbilical artery hemodynamic change index (CDFI, S/D), and evaluate whether the fetus is suffering from intrauterine hypoxia.

3. Post-delivery examination

Observe whether the placenta is retained and the condition of uterine involution. Therefore, pregnant women should undergo necessary perinatal examinations in these four specific stages under the guidance of a doctor to provide a reliable basis for treatment.

Advantages of 3D color Doppler ultrasound

1. Add coronal section images while retaining two-dimensional imaging.

2. Stereoscopic positioning and axis adjustment. The three axes of ABC can be adjusted at will until the best image is displayed.

3. Stereoscopic imaging, dynamic and intuitive; it can observe the fetal head, body surface and internal organs activities in real time, and the image is clear, accurate and reliable.

4. Cutting function can retain the key points of the image. The useless parts are cut off and the suspicious parts are reconstructed and displayed in three dimensions.

5. Rotation function allows for multi-faceted observation; it has 360° rotation functions in front, back, left, right, up and down directions, allowing for comprehensive observation of images from different directions.

6. You can take beautiful photos of the fetus, record the changes in facial expressions and burn them to a CD for storage as a permanent commemoration.

7. It can display the three-dimensional relationship and adjacent relationship of lesions at different levels. The application of three-dimensional color ultrasound in obstetrics provides rich imaging information for clinical ultrasound diagnosis. The fetus is surrounded by fluid in the amniotic cavity, which is a good imaging condition for three-dimensional ultrasound. The image is three-dimensional, vivid and intuitive, and the angle can be adjusted at will. Suspicious structures can be observed through the rotation of three sections, and the gross structural deformities of the fetus can be seen at a glance, which greatly improves the quality of diagnosis and treatment and reduces misdiagnosis or missed diagnosis.
