Before 40 days of pregnancy,according to the maximum embryo sac diameter (GSD) or the length from the top of the head to the posterior buttocks(CRL),gestational age can be estimated by the following formula:GA=(6×GSD )+20 or GA=(3×CRL)+27.40 days after gestation,according to the maximum head diameter of the head(HD) or the maximum body cavity diameter(BD)at the level of the liver,gestational age can be estimated: GA=(15×HD)+20 or GA=(7×BD)+29,GA=(6×HD)+(3×BD)+30.
In the formula, the unit of length is cm and the unit of gestational age is d.
