Can a 4D Ultrasound Clearly Show Finger Details?

4D ultrasound cannot display the number of fingers of the fetus, thus it is also difficult to determine whether there are cases of extra fingers or missing fingers. As long as the fetus's hand posture is natural and coordinated, the diagnostic purpose is achieved. Many fetuses with extra fingers are born without affecting the function of their hands, and missing fingers do not have a significant impact on their life after birth. In terms of the entire human body, the deformity of fingers does not have a significant impact on the life of people after birth. Therefore, current medical examinations, whether it is 4D ultrasound or ordinary ultrasound, do not include the fetus's fingers in the screening for deformities. Compared with ordinary ultrasound or B-ultrasound, 3D or 4D ultrasound has great advantages and can detect more deformities. However, it is not omnipotent and cannot see any part of the fetus. It is also affected by many factors such as the fetus's position, the amount of amniotic fluid, the umbilical cord, the mother's physical condition, and the performance of the machine. Generally, when performing 3D or 4D ultrasound, it is often mentioned that the fetus's fingers, toes, and ears are difficult to see, so deformities in these areas are not excluded from 3D or 4D ultrasound examination. In addition, the fetal facial examination does not include cleft palate alone or very small cleft lip alone, and deformities in the fetal reproductive organs are also not included in the screening range due to limitations in current medical technology and equipment. Please understand this, pregnant mothers. The best time for 4D ultrasound is between 26 and 30 weeks of pregnancy. Before 26 weeks of pregnancy, there is still very little fat under the skin of your baby, so the bones of the face will protrude through the skin. After 30 weeks of pregnancy, your baby's head may enter your pelvis, making it difficult to see his face.
