Ultrasonic Fetal Measurement Standards If we assume a fetus is growing normally, biometric measurements are determined by gestational age, and we can estimate the gestational age and thus the due date. Conditions which alter fetal growth will make the estimates less reliable. Although many embryonic and fetal structures can be measured, only a few measurements are easy and repeatable enough for widespread use.
The most common are: The first element to be measurable is the gestation sac of the early pregnancy. The gestational sac is measured in three dimensions, and the average, the Mean Sac Diameter MSD used for estimating gestational age. The length of the embryo on the longest axis excluding the yolk sac constitutes the crown-rump length. The transverse width of the head at it’s widest. We measure from the the leading edge to leading edge of the bones, because this leading interface is most distinct.
The estimated date of confinement EDC is the date birth is expected the due date. Ultrasonographic measurements of the fetus in the 1st trimester give the most accurate estimate of embryologic age. When menstrual cycles are irregular or data are unreliable or not available, ultrasonography may be the sole source of the EDC. Newborn physical examination findings also allow clinicians to estimate gestational age using the new Ballard score.
The Ballard score is based on the neonate’s physical and neuromuscular maturity and can be used up to 4 days after birth in practice, the Ballard score is usually used in the first 24 h.

For example, not every woman ovulates on Day Other situations that Naegele did not factor into his calculation were ethnicity, parity how many successful pregnancies , prenatal care , better nutrition, and screening factors.
