9-month-old USG Examination Results?
I am 37 weeks pregnant. But when ultrasound FL my fetus is 67.7mm is it still normal?
Thank you for the question on HealthReplies.com,
The use of ultrasound (Ultrasonography) in imaging fetal development is common and relatively safe to do. Ultrasound uses high-frequency sound waves to create black and white images based on the density of organs and body parts to be evaluated.
There are several assessments that can be done when ultrasound on the fetus, including:
Determine fetal heart rate / fetal vitality. Estimating the gestational age of a baby (gestational age). Ascertain the number of fetuses in the womb. Look at the condition of the placenta and amniotic fluid. Find defects in the fetus. Carry out checks if complications occur such as bleeding. Determine the position of the fetus before birth. Determine fetal development, see head circumference, abdominal circumference, and length of the femur. FL on ultrasound examination can indicate the length of the femur (Femur Length). Also note that differences in gestational age can be found by calculating the First Day of Last Menstruation with an examination algorithm from the USG results because it has its own calculations based on the results of measurements on the fetus. According to the research of Hadlock et al. comparing measurements of femur bone length with gestational age, at nearing 37 weeks can have a femur length of 72 mm. (1)
It should be noted that in the indicators of determining gestational age, fetal growth and development also look at head circumference and fetal abdominal circumference. For more information about the condition of the fetus, you can consult an obstetrician regarding ultrasonography.
Hopefully this information can help you,
