Application of Carnegie stages of development to unify human and baboon ultrasound findings early in pregnancy
J Santolaya-Forgas, J De Leon-Luis, LA Friel… - Ultrasound in medicine & …, 2007 - Elsevier
The objective of this study was to determine if very early ultrasonographic measurements
obtained from human and baboon are comparable. For this purpose, the gestational,
amniotic and yolk sacs, embryonic crown rump length (CRL) and heart rate were measured
ultrasonographically between 35 and 47 days from the mean day of a three-day mating
period in baboons (n= 18) and between 42 to 58 days from fertilization as calculated from
the CRL measurements in human pregnancies (n= 82). Ultrasonographic measurements …
