Ultrasonography has advanced obstetric practice by enabling relatively detailed assessment of the fetus, including an accurate estimate of gestational age when performed before 22+0 weeks of gestation. This information is invaluable because most diagnostic and management decisions during pregnancy are …The mathematic formula for estimating the gestational age from measurements of the gestational sac is: Gestational age = 4 weeks plus (mean sac diameter in mm x days). For example, a gestational sac measuring 8 mm would be approximately 5 weeks and 1 day gestational age. (8mm equals 8 days; 4 weeks plus 8 days = 5 weeks and 1 day).

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. Similarly, the authors reported a 4.4% false-positive rate for early pregnancy loss when using a mean gestational sac diameter cutoff of 16 mm. A mean gestational sac diameter cutoff of 21 mm (without an embryo and with or without a yolk sac) on the first ultrasound examination was required to achieve 100% specificity for early pregnancy loss.Normal sacs become visible when they reach 2 to 3 mm.
