A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.
By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy.
The most accurate time is between 8 and 11 weeks gestation. This is because the fetus is growing so quickly that there is a big difference in size from week to week. However, the accuracy of the ultrasound examination is always dependent on the skill of the sonographer and the quality of the equipment. The EDD from the early dating scan is used – if the last menstrual period is not known or is unreliable, or the dating scan differs from the last menstrual period dating by more than 5 days.
Ultrasound examinations from 12 to 22 weeks are regarded as being within 10 days of accuracy or up to 10 days earlier or 10 days later than the woman’s calculated due date.
The main purpose of a dating scan is to check the stage of pregnancy and therefore when the baby is due. Measuring the baby can be more accurate than dating by the last menstrual period. It is also an opportunity to check the baby is alive and developing as expected, and check for twins. This scan may also be part of your screening test for Down’s syndrome nuchal translucency scan.

This is a scan or ultrasound which determines your expected date of confinement EDC based on the development of the embryo. The limbs and the yolk sac, though obviously important, are not the primary means of measuring growth.
An average length of the embryo at 7 weeks is anywhere between 5mmmm. The average weight is less than 1 gram. Obviously, every pregnancy is unique and individual factors influence the size of the embryo at this early stage, and the embryo shows development week by week. The ideal time for a sonographer to assess the gestational age in the first trimester is between weeks of pregnancy.
This is the period of time which provides the most accurate assessment. Generally, ultrasounds which are performed in the first trimester are within days of being accurate in terms of assessing gestational age. This is because although every little embryo is unique, there are still defining characteristics of development which apply to all embryos at particular stages of early gestational development.
As the embryo matures to a foetus, individual genetics and growth factors influence its growth. 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.
