The dating scan is an ultrasound scan that can be done as early as six weeks after the last period, but the dating scan will be most accurate when done between 8 and 12 weeks gestation.
For many expecting mums who do not want to go down the route of screening for a chromosomal abnormality such as Down’s syndrome then this scan can be performed to give reassurance that all is well up to 18 weeks of pregnancy.
The dating pregnancy scan performed between 6 – 18 weeks will confirm: That a gestation sac is seen within the uterus i.e. By 6/7 weeks in pregnancy it is possible to detect the baby’s heart beat(s) We measure the baby’s head (crown) to bottom (rump) length (CRL) allowing us to determine how many weeks pregnant you are.
Even dating scans can be inaccurate for the due date, but they are never as inaccurate as using the menstrual period.
For instance a dating scan done at 6 weeks could get the date wrong five days either way.
A full report will be issued to put in your obstetric records.
We encourage you to show this report to your healthcare professional looking after your care.This is normally done in the consulting room for a small out of pocket cost.This cost is nowhere near the out of pocket cost if the scan were to be performed at a radiology practice.Seeing a positive pregnancy test can bring about a host of emotions, thoughts and questions.One question many mothers have is when can they see their baby’s heartbeat on ultrasound.Should a problem be found, we will make all the necessary arrangements for follow-up care at a suitable time and location of your preference.
