The Dating Ultrasound Scan
The dating pregnancy ultrasound scan is being use to detect the gestation age of the baby, 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. This pregnancy scan also known as viability 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 mothers choose to have their ultrasound scan with us for peace of mind.

What is included with this ultrasound scan?
Ultrasound report with a 2D b/w picture
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 scan our sonographer will explain the examination procedure and discuss the reasons for having the scan.
You will lie on the examination couch, asked to expose your lower abdomen and a small amount of gel will be placed on the skin. The ultrasound probe will be moved in different directions to obtain the best possible images.
Depending on the image quality of the transabdominal scan (TS), an internal or transvaginal scan (TV) might be necessary. Our sonographer will explain the reasons and the procedure and will get your consent.
About the Pregnancy Ultrasound
Pregnancy or baby ultrasound scans are very common part of prenatal care. This is because ultrasound scans are completely painless, have no known side effects on mothers or babies, and can be carried out at any stage of pregnancy: in early pregnancy, ultrasound is being used to confirm the baby's heartbeat and exclude any early stage abnormalities; later in pregnancy ultrasound is being used to evaluate the baby's oveall health.
Ultrasound imaging is a medical diagnostic technique where sound waves are being used to image various parts of the body.
Other terms for ultrasound imaging are: sonograms, US and sonography.
Ultrasound is widely used these days as it is painless and safe to adults, children and foetuses. There are no side effects such as the ones associated with radiation.
During the ultrasound scan, the sonographer rests a small probe over the skin. This probe produces sound waves i.e pulsations that travel through the tissues. Some of the sound waves are being reflected back to the transducer and the computer analyses the returning echoes and produces the image on the screen. It is the same principle with the sonar the navy uses.
Ultrasound is being used to image mostly solid organs such as liver, kidneys, uterus and ovaries, muscles and blood vessels and babies in the womb.
It has however limited value in organs such lungs, bone, stomach and bowel/colon.
Ultrasound images are black and white but colour Doppler is being used to evaluate organ and blood vessel blood flow and this is what the red and blue colours on the screen are.
