Fetal Crown-Rump Length Graph
This simplified fetal growth curve shows a constant and continual growth in fetal length through second and third trimester.
Crown-Rump Length - (CRL) measurement used in embryology to more accurately stage the early embryo and fetus. Measured from the curvature at the top (crown) to the curvature at the bottom (rump) of the "C-shaped" early embryo. Used in clinical ultrasound as a measurement between the periods of 7 to 13 weeks as an accurate estimation of the gestational age GA.
