Ultrasound

What is an ultrasound?

An ultrasound scan is a medical procedure that uses high-frequency sound waves to create live images inside the human body with no adverse effects on the foetus. During the ultrasound procedure, you lie on your back with your lower abdominal area uncovered. The ultrasound probe is moved over this area, gliding on a water-based gel. You will then be able to see ultrasound images on a monitor. 

There are a number of reasons why the first trimester ultrasound is important: 

  • to make sure the pregnancy occurs within the uterus
  • to confirm a heart beat
  • to see whether there is one or multiple babies
  • to estimate the due date as accurately as possible

 

Further on in the pregnancy, an ultrasound can give the following information:

  • The baby’s growth rate
  • The amount of amniotic fluid
  • The location of the placenta
  • The position of the baby
  • The baby’s organ development

 

At our practice, we offer our clients the following ultrasound scan procedures:

The first trimester ultrasound

The First Trimester ultrasound is to be performed in the first 3 months of a pregnancy. The procedure can be performed vaginally or externally over the lower abdominal area. The type of ultrasound probe used depends on on the length of the pregnancy and your body weight.

The objective of the ultrasound scan is to determine the location of the foetus and whether this is a single or multiple pregnancy. During this time, the foetal heart beat can be detected. Between 10-12+6 weeks, the pregnancy term and due date can be established.

Structural ultrasound examination (SEO)

The 20 week ultrasound is also known as the ‘anomaly scan ’. This ultrasound is generally used to look for signs of neural tube defects, as well as other physical abnormalities. Examples of these are: anencephaly, spina bifida, heart anomalies, herniation of the diaphragm, internal herniation, kidney and bone abnormalities, and abnormalities of the limbs. This ultrasound will also check the growth rate of your baby and whether there is sufficient amniotic fluid. The 20 week ultrasound takes place between 18 and 21 weeks.

Beforehand, you will receive advice and a folder with all necessary information so that you can make an informed decision on whether you want to opt for the 20 week ultrasound. The 20 week ultrasound does not guarantee a healthy child. Not all abnormalities can be seen via ultrasound. You will have the results of this scan immediately. If any physical abnormality is detected, the true extent of the effects upon the child are not always clear. A second test is then usually recommended. You will be given in depth information on additional testing during your appointment with the ultrasound technician. midwife, General Practitioner, and/or gynaecologist. All your questions can be directed to them. It is sometimes necessary to undergo a second ultrasound after 4 weeks. This is often done to check the baby’s rate of growth.

Fetal growth scan around the 30th til 33th week

If considered of medical importance a growth ultrasound will be carried out at 30 weeks.
Your baby’s rate of growth will be checked. The amount of amniotic fluid will also be measured and the position of the placenta will be visualized. In some cases this scan is repeated at 33 weeks.

Position of the placenta scan
In some pregnant women the placenta lies close to the cervix. This is called a low lying placenta or placenta praevia. This could have consequences during labour. After 33 weeks, the placenta has almost stopped growing. This scan measures how far the placenta is from the cervix. Sometimes the position of the baby’s head makes this measurement difficult, in which case an internal (vaginal) probe will be used.
Fetal lie scan
If there are any doubts as to the position of the baby after regular check ups from the 35th week onwards, a positioning scan will be carried out. Growth measurements will also be made, as well as making sure there is sufficient amniotic fluid. If the baby’s head has settled in the down position it is difficult to make head measurements.
Fetal gender reveal scan
As from September 1st 2015 we also offer you the opportunity to determine the gender of your baby via ultrasound. You can do this as from 16 weeks.  In some cases, for example when the baby is lying on its tummy, it is not possible to determine the gender. You will then receive a second (free) scan if you wish so. You can pay for the foetal gender scan via bank card at the reception.
