Essential skills for understanding fetal development
At 15 weeks of pregnancy, the fetus has entered the development stage of muscles and bones. Fetal 4-dimensional color ultrasound examination at this time can provide an in-depth understanding of the physical condition and development of the fetus. The following is a detailed explanation of the 4-dimensional color ultrasound image of the fetus at 15 weeks of pregnancy from four aspects.
Fetal size and weight
At 15 weeks of pregnancy, the size and weight of the fetus has increased significantly. Through 4-dimensional color ultrasound, the overall shape of the fetus and the brown fat layer can be clearly observed. The fetus at this time is about 9 cm long and weighs about 70 grams. The fetus\’s limbs are also becoming more and more obvious, the joint curvature of the fingers and toes has been completed, and the webbing between the toes has gradually disappeared.
Development of fetal organs
At 15 weeks of pregnancy, most of the fetus\’s vital organs have formed. Through 4-dimensional color ultrasound, the fetal heart, brain, liver, lungs and other major organs can be clearly observed. The heart beats 120-160 times per minute, and four heart chambers have been formed. At this time, treatment operations such as drawing blood from the abdominal umbilical cord can be performed. The lungs have also protruded from the simple extraembryonic sac into the chest cavity, indicating that the fetal respiratory system is also gradually developing.
Identification of fetal gender
At 15 weeks of pregnancy, the gender of the fetus can be identified through 4-dimensional color ultrasound. Normally, a boy\’s penis will be formed at this time, while a girl\’s vulva will be exposed. However, it should be noted that gender identification is not 100% accurate and may contain errors. In addition, some pregnant women do not want to know the gender of their fetus and need to inform the doctor or technician in advance.
Related indicators of pregnant mothers
During the 4-dimensional color ultrasound examination of the fetus, relevant indicators of the pregnant mother can also be measured. For example, the health of the fetus and mother can be assessed by measuring parameters such as amniotic fluid depth, placental position and flow in pregnant mothers. On this basis, timely intervention and treatment can help ensure the smooth development of the fetus and the health of the mother.
In short, a fetal 4-dimensional color ultrasound examination at 15 weeks of pregnancy can fully understand the physical condition and development of the fetus, grasp and solve possible problems in a timely manner, and help provide the best protection and help to the fetus. Pregnant mothers also need to maintain a good mentality and health status to provide strong support for the healthy growth of the fetus.
