The anomaly scan at weeks of pregnancy looks for some physical scan only looks for these conditions, and cannot find everything that might be wrong.

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. Ultrasounds performed after 22 weeks gestation cannot be used to estimate the due date of the baby because the size no longer reflects the age very well.

Ultrasound Accuracy for Predicting Due Dates

Because the changes are happening internally, doctors can’t feel them from the outside. However, transvaginal ultrasounds reveal the shape of the entire cervix, allowing doctors to see if the process has started, Berghella said. Estimating due dates more closely could help doctors make medical decisions. For babies with congenital anomalies who must be delivered in a hospital, getting a better estimate of the due date could ensure safer delivery.

And hospitals could make arrangements to have more staff on hand if they know lots of deliveries are imminent in the next week, Berghella said.
