How many weeks does 3D B-ultrasound

Three-dimensional B-ultrasound is a very advanced technological advancement today. It can clearly show the appearance of the fetus and the dynamics of the fetus in the uterus, such as opening eyes, sticking out tongue, etc. There is still a certain effect of three-dimensional B-ultrasound for pregnant women, which has the actual effect of screening for fetal abnormalities. So how many weeks is best to do 3D B-ultrasound?

When to do 3D B-ultrasound

Ordinary B-ultrasound only shows a two-dimensional image, while 3D B-ultrasound shows a three-dimensional image. The fetus can be seen from the front, back, left, right, and right sides, which is more comprehensive, true and clear. Three-dimensional B-ultrasound has significant advantages in diagnosing fetal epidermal structural malformations such as cleft lip and palate, spinal malformations, heart malformations, and central nervous system malformations. Three-dimensional B-ultrasound is usually performed between 24 and 28 weeks of pregnancy.

It is often chosen to do a 3D B-ultrasound at 24-28 weeks of pregnancy because during this period of time, the structure of each organ of the baby is relatively complete, and the doctor can see it very clearly during the examination. The B-ultrasound examination takes a relatively long time and has high requirements for the doctor who performs the examination. It is best to be performed by a qualified and rigorously trained doctor to minimize the misdiagnosis of functional malformations.

If the fetus's previous ultrasound NT exceeds 3mm, the mother has given birth to a baby with heart disease, or the adult has heart disease, the mother has diabetes, and takes certain medications, a professional fetal heart ultrasound examination may be required. If the 3D B-ultrasound examination suspects that the fetus has abnormalities in the head, lungs or other organs, a fetal MRI examination may be required in conjunction with the 3D B-ultrasound examination for diagnosis.

The efficacy of 3D B-ultrasound

1. It can promptly diagnose fetal malformations, including surface malformations and visceral malformations, especially head and facial malformations that cannot be displayed by two-dimensional color ultrasound, such as cleft lip, flat face, triangular head, incomplete mandible, flat nose, anteroverted nasal cavity, monocularity, macrostomia (transverse facial cleft), etc.

2. The information can be scanned and displayed step by step in all directions at will, providing a more detailed analysis of the fetus.

3. Accurate positioning of the fetus in the uterus.

4. Confirm the baby’s brain disease.

5. Clearly display the internal characteristics, surface shape and spatial position of gynecological tumors, which is helpful for early distinction between benign and malignant changes.

It is necessary for expectant mothers to do three-dimensional B-ultrasound. It has many functions. I believe that after reading the above introduction, expectant mothers will also understand it clearly. Complete the inspection within the required time and feel at ease.
