Pregnant women in the process of pregnancy, the most important for timely acceptance of prenatal care. Most of the health check-ups listed in the Handbook of Pregnant Women's Manual were made by the Health Insurance Bureau two decades ago and can grasp the general situation of the fetus. With advances in medical science and technology, the "High-Level Ultrasound" childbirth test at its own expense program between 20 and 24 weeks of pregnancy allows us to grasp more detailed health status of the fetus from the brain to the limbs.Dr. Zhong Ji Xian said that the current national health insurance system to pay two prenatal ultrasound examination costs, respectively, in early pregnancy and about 20 weeks of pregnancy, belong to the basic items of inspection, the main assessment of fetal size, fetal position, amniotic fluid volume and placenta position. At 20 to 24 weeks of pregnancy, the baby's organs have developed to some extent. Through the "high-level ultrasound", the fetus can be subjected to whole-body organs. The detailed examination of the structure from the brain to the limbs allows parents to understand the health of the fetus , If any abnormalities can be tracked immediately after birth treatment.Zhong Jixian shows that high-level ultrasound belongs to 2D images and is a traditional ultrasound. 3D reorganizes many 2D images into a stereoscopic image, and some information may be distorted. If the time axis is added, it becomes a 4D ultrasound. Although the fetus can be seen Appearance, whether the appearance of defects such as rabbit lips, but can not tell whether the baby has anomalies within the structure, it is still 2D ultrasound has diagnostic value.High-level ultrasound detection of fetal abnormalities, the accuracy rate of about Bacheng, the main influencing factors are pregnant women body size, amniotic fluid volume, baby posture and number of weeks of pregnancy. Pregnant women too thick layer of fat, amniotic fluid too little or baby's position just to block the site to be checked, may cause blurred images. In addition, the number of weeks of pregnancy is too small, baby organs have not yet developed, the week is too large, the baby is not easy to do in the wig flip action, so 20 to 24 weeks of pregnancy is the best time to check. In particular, have produced abnormal fetal exposure to teratogenic drugs or long-term exposure to radiation in pregnant women, are recommended to accept high-level ultrasound examination....
