Gestational sac diameter as a function of gestational age was compared in each of the groups. Results: The mean diameter of the gestational sac at 28-35 days from the last menstrual period among normal pregnancies did ...Ultrasound technicians measure the MSD and look for certain structures within the gestational sac that should be present. For example, When the MSD is 5 mm, it is possible to see the yolk sac. A smaller than expected sac around 7- 8 weeks (but not before) indicates that the pregnancy is not progressing normally and will end in miscarriage.A compound bar chart is a bar graph with secondary and tertiary information measured on the same bar often with a colored key. A bar graph measures frequency data. Compound bar cha...Determine the length, height, and width of the gestational sac located on the ultrasound and enter these values in the calculator. The mean of these summed values will be calculated automatically. Based on this value, we will find the estimated gestational age in days using the built-in mean sac diameter chart.

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.
