Some sonographers believe that at seven weeks of gestation, transvaginal ultrasound provides the best and most accurate visualisation.

The ideal time for a sonographer to assess the gestational age in the first trimester is between 7-10 weeks of pregnancy.In some respects the seven week ultrasound can be quite accurate because the embryo is developing very quickly.They are also not as mobile and active as they will be with future development.This is why an early pregnancy dating scan, rather than one done in the later stages of pregnancy, is considered more accurate when assessing the expected date of delivery.With maturity, the size of the baby correlates less to its age than in the early weeks.
