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.
The most common reasons for having this ultrasound scan include:
The purpose of this scan is:
The scan incudes Ultrasound Report with a 2D b/w picture
We need your bladder full for this scan so you need to drink 1lt (2 pints) of water an hour before your scan.
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.
