Dating ultrasound scan: 11 to 14 weeks

The dating ultrasound Scan



A Dating baby scan is being use to detect the gestation age of the foetus. Something very useful for women who are uncertain of their last menstrual period or have irregular menstrual cycles and therefore making it difficult for their doctor to correctly estimate when the baby is due.

Ultrasound is very accurate estimating the baby's due date and the earlier the scan the better the accuracy. The most accurate time is between 8 and 11 weeks gestation.  In general ultrasound scans performed during the first trimester are within 3 - 5 days of accuracy. After 28 weeks, the stimation of the due date can be as long as 3 weeks out.

The overall accuracy of the scan also depends on the skills of the sonographer and the ultrasound scanner quality and this why our sonographers are all NHS qualified sonographers and we are using the latest ultrasound machine.

This pregnancy scan also known as viability ultrasound scan can provide the very much needed reassurance that the pregnancy is progressing normally and it is not an ectopic.

Unfortunately dating pregnancy scans are not routinely offered in the NHS and our expectant couples choose to have their ultrasound scan with us for peace of mind.

Preparation for this ultrasound scan?

We need your bladder full for this scan so you need to drink 1lt (2 pints) of water an hour before your scan.


What should I expect?

Before the ultrasound scan, our sonographer will explain the examination procedure.

This scan is normally performed trans-abdominally. In some instances, however an internal scan (Trans-vaginal) may be required to see all the necessary detail or if your womb tilts backward.  

We will always try to scan trans-abdominally first but if we need to do an trans-vaginal ultrasound scan then we will discuss this with you. To perform this baby scan, you will be asked to lie down on the examination couch and expose your lower abdomen.

A small amount of water-based gel will be applied to your skin. The gel will help the transducer to make good contact with the skin. The ultrasound transducer will be placed on the body and will be moved in different directions over the area of interest to obtain the required information/ultrasound images.

There is usually no discomfort from pressure as the transducer or probe as otherwise known,  is pressed against the area being examined. However, if scanning is performed over an area of tenderness, you may feel pressure or minor discomfort from the transducer.

Once the ultrasound imaging is completed, the clear ultrasound gel will be wiped off your skin. Any portions that are not wiped off will dry quickly. The ultrasound gel does not usually stain or discolor clothing.

This ultrasound examination is usually completed within 20-30 minutes. After an ultrasound examination, you should be able to resume your normal activities immediately.

As ultrasound scans are pregnancy friendly your doctor wight refer you for an abdominal/liver scan or a kidney scan to check for anything that might explain your symptoms.

About Ultrasound

Diagnostic Medical ultrasound scan or medical sonography as otherwise known is a painless imaging technique utilising sound waves to produce internal images of the body.
It is called ultrasound as the sound frequency being used is at the region of 1 to 20MHz. The human ear cant can’t hear these frequencies.
The sound waves are produced by the transducer or the probe as most commonly known. As they travel through the body they bounce back to the transducer due to various sound transmissions differences in tissues. The returning echoes are picked up by the probe and a powerful computer analyses the echoes and creates the 2d image on the screen.
There are various kinds of ultrasound scans that can be performed and each looks at different organs of the body such as tendons, muscles, joints, blood vessels, liver, kidneys, uterus and ovaries to confirm or exclude possible pathology.
Unlike Ct and MRI, ultrasound does not use radiation and therefore is pregnancy friendly. It is also live and is ideal for musculo-skeletal exams to evaluate moving joints.

The dating scan is being used to see how far along in your pregnancy you are and check your baby's development. This ultrasound scan can routinely detect a baby's heartbeat as early as 6-7 weeks and confirm the correct dates of your pregnancy. Something very useful for women who are uncertain of their last period or have irregular menstrual cycles and therefore making it difficult for their doctor to correctly estimate when the baby is due.
A nuchal screen at 12 weeks and then a 20 week anatomy scan. If there is a problem later such as large or small for dates you will most likely offered more scans. It really just depends on your pregnancy.
A gestational sac can be seen as early as the fifth week of pregnancy or three weeks after conception. If no gestational sac is seen, it could mean that the expectant mother ovulated later than believed. Your doctor will recommend a follow up ultrasound scan in a few days or a week.
Ultrasound scans performed during the first 12 weeks of pregnancy are generally within 3 - 5 days of accuracy but the most accurate time is between 8 and 11 weeks gestation.
