During pregnancy, pregnant women need to undergo regular prenatal check ups to understand the growth and development of the fetus. At a certain stage of pregnancy, pregnant women can undergo color ultrasound. The scope of color ultrasound examination is relatively wide, including the fetal face, spine, urinary system, amniotic fluid, placenta and other aspects of development. The color ultrasound sheet also includes FL examination. So, what does maternal color ultrasound FL represent?
The prenatal ultrasound FL represents the femur length of the fetus. Femoral length refers to the length of the thigh bone, which is used to observe whether the fetus is developing normally. The femur length of the fetus can be calculated from the 13th week of pregnancy. The first week to the 12th week of pregnancy belong to the early stage of pregnancy, and the fertilized egg begins to implant and develop. By the 13th week, the various reproductive organs of the fetus begin to develop, and then the development of various organs gradually tends to be more complete.
As the fetus continues to develop, the standard for fetal femur length varies at different stages of pregnancy. The fetus is constantly moving in the pregnant woman's body, and its position is constantly changing. Sometimes, the value of femur length may be affected by fetal fluctuations and change. Therefore, if there is a significant error in the value of femur length, pregnant women do not need to be too nervous and should undergo a follow-up examination to see the results.
There are many reasons that can affect the development of femur length. If the fetus is not fully developed, the development of femur length will not be very good. Pregnant women should conduct timely health checks for both the fetus and themselves in order to make early adjustments to adverse conditions.
