According to nctpregnancyandbabycare.com, "Scan technicians estimate the length of the pregnancy by measuring the embryo and comparing these results with a chart of standard sizes/gestations. The earlier the scan is performed, the more accurate these comparisons. Even so, scan 'dates' are only accurate to within five days. A scan performed later than 20-24 weeks cannot accurately assess gestation." == In addition 2 different techs even on the same day can get 2 different sets of results, it can vary because of their techniques or because of the position the baby is in. If you have to go for numerous scans & want consistancy, ask for the same tech every time you go. It also depends on the age of the machine, they can be quite finicky...the newer ones do all the figuring for the techs all they have to do is input the data they are receiving.
