Ultrasound scans use sound waves to create a picture of the baby in the womb. Most women have one or more ultrasound scans during pregnancy. The two scans routinely offered during pregnancy are the nuchal scan and the anatomy scan. Sometimes other scans are performed earlier or later in pregnancy to check the growth of the baby, the position of the baby or the placenta, or for other reasons. A baby and heartbeat can be seen on the scan after 6 weeks. Before 6 weeks it is not always possible to see the baby as it is too small.

Time for your 12-week scan? Here’s what to expect…

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.[rs_table_products tableName=”Best Dating Websites”]

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. Even average babies can differ by up to 2 to 3 “weeks of growth”;. These scans are only used to estimate the due date of your baby if this is all you have to go on. If you have more than one ultrasound during your pregnancy, giving you ‘multiple dates’, then the earliest ultrasound estimate should be used, because it will be more accurate.
