Practical points Learn about gestational sac evaluation in early pregnancy ultrasound. Understand its purpose, timing, measurements, and implications for the diagnosis of early pregnancy to ensure appropriate management and follow-up care. Measurement of a crown-rump length during the first trimester (1-13 weeks) will give a gestational age that is usually accurate to within 3 days of the actual due date. During the second trimester (14-28 weeks), measurement of the biparietal diameter will accurately predict the due date within 10-14 days in most cases. Measurement of a crown-rump length during the first trimester (1-13 weeks) will give a gestational age that is usually accurate to within 3 days of the actual due date.
