Hello everyone, many friends don’t quite understand the three-month fetal color ultrasound, but it doesn’t matter, because today I will share with you the femoral length standards for three-month-old fetuses. What is the knowledge point about how much fetal development is good? I believe it should be able to solve some of your confusions and questions. If it happens to solve your problem, please pay attention to this site. I hope it will be helpful to you!

What is the standard length of fetal femur in one and three months? I don’t know about fetal development?
Three months pregnant Month refers to the 12th week of pregnancy. At this time, the femur of the fetus is about 1 cm long. At 12 weeks of pregnancy, the crown-rump length and biparietal diameter can usually be measured, and these data will be provided in subsequent B-ultrasound examinations to comprehensively understand the fetal development. In addition to these related examinations, NT examination, Down syndrome screening and fetal system ultrasound examination are also required.
2. What is the third-level fetal ultrasound examination
Three-level fetal ultrasound Ultrasound screening is a detailed structural examination of various fetal organs. Obstetric ultrasound is divided into four levels. Level 1 ultrasound examination is a routine examination, mainly screening for fetal development in early pregnancy; level 2 ultrasound examination mainly screens for obvious fetal malformations; level 3 screening is the most important examination during pregnancy, mainly screening for fetal development. Whether there are developmental abnormalities in various organs; Level 4 ultrasound examination is prenatal diagnosis. Evaluate production methods. Obstetric ultrasound is currently the best way to detect fetal development.
3. How to read the three-dimensional color ultrasound report data
Three-dimensional color ultrasound Mainly look at the following data indicators, taking fetal three-dimensional color ultrasound as an example: see whether the fetal skull outline is complete, and whether the midline of the brain is not displaced or hydrocephalus; look at the size of the fetal biparietal diameter, the biparietal diameter of a full-term fetus ranges from 8 to 10 cm, color ultrasound The instrument can estimate fetal weight through data such as biparietal diameter.
Check whether the fetal heart rate is normal, the normal fetal heart rate is 120 to 160 times per minute; look at the position and thickness of the placenta, the position of the normal term placenta cannot be previa, and the thickness is 2.5-5 cm;
Look at whether the umbilical cord is wrapped around the neck; look at the amount of amniotic fluid, the normal range of amniotic fluid depth is 3-7 centimeters; look at the length of the femur, the normal value should be consistent with the corresponding pregnancy The difference in biparietal diameter values between months is less than 2-3cm.
4. How long after pregnancy can you have a three-dimensional color ultrasound
After pregnancy Three-dimensional color ultrasound can be done between 22 and 26 weeks to rule out malformations, because during this time there is more amniotic fluid and the fetus moves more frequently, which helps to check the development of the child\’s various organs, so you should make an appointment with the hospital in advance. For examinations, it is recommended not to exert yourself, check whether the fetal movements are normal in the second trimester of pregnancy, and try not to catch a cold.
