The crown–rump length (CRL) is measured as the greatest length in a straight line from the cranial to the caudal end of the body in the straightest possible position of the embryo/fetus (Fig. 4.7). The CRL diagram presented by Robinson in 1975 is still widely used for the evaluation and dating of the early pregnancy. 11Introduction: In the past, heart activity was only visualized by ultrasound in embryos with a crown-rump length (CRL) of 5 mm or more. When CRL was shorter than 5 mm, non-visualization of heart activity was considered normal. However, improvement in ultrasound equipment resolution has made it possible to diagnose viability in embryos with CRL as small as 2 mm.Comparison of different formulas for calculating gestational age (in days) by crown-rump length (in mm) IG21, International Fetal and Newborn Growth Consortium for the 21st Century.
