For a healthy gestation, it is suggested that the mean sac diameter should be at least 5 mm greater than the crown rump length.

Disorders late in gestation cause asymmetric growth restriction, in which weight is most ...On abdominal ultrasound, a yolk sac is present. Three measurements of the gestational sac are 2.1 cm, 2.7 cm, and 2.5 cm, giving a mean sac diameter of 2.4 cm, consistent with a 7w0d IUP. MSD is the earliest measurement that can assess GA. MSD can be used until the embryo is present (5w0d-8w0d), then use the CRL.
