Abstract:
Study the correlation of fetal crown-rump lengtht (CRL) measurement and gestational age of 6 to 14 weeks in 100 pregnant women. Results: there is a close correlation between CRL measurement measured by ultrasound and gestational age, with correlation function y = 0.86x2 - 7.53x - 18.78; correlation coefficient r = 0.998. Thus ultrasound can be used to measure CRL for diagnosis of gestational age, with the range was within 3.7 days of menstrual age. The rate of change in CRL was 7 mm/week between 7-10 weeks and 13.5 mm/week between 11-14 weeks
