Ultrasound

What is an ultrasound?

An ultrasound is the perfect way to visualise and examine a pregnancy. During the ultrasound you lie on your back with your belly bare. The ultrasound probe is moved over your belly, gliding on a water-based gel. You will then see ultrasound images on a monitor. Ultrasound uses out of hearing range sound waves and are not at all dangerous to you or your baby.
There are a number of reasons why you should undergo an ultrasound early on in your pregnancy:

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

Further on in the pregnancy an ultrasound can give other types of information:

  • The growth rate
  • The amount of amniotic fluid
  • The location of the placenta
  • The position of the baby
  • Organ development

At our practice, all of our clients have the opportunity to undergo the following ultrasound scans:

Periodical ultrasound

This scan, done in the first 3 months of a pregnancy, makes sure that the pregnancy takes place in the uterus, and can see whether there are single or multiple pregnancies. The heart beat of the baby is also detected.
Between 10 and 12 weeks + 6 days the pregnancy term and due date can be established. The periodical ultrasound can be done vaginally or via the belly. The type of ultrasound probe used depends on the length of the pregnancy and your body weight.

It is sometimes necessary to repeat this periodical ultrasound two weeks later.

Structural ultrasound examination (SEO)

The 20 week ultrasound is also known as the ‘structural echoscopic examination’. 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 19 and 22 weeks.
Beforehand, you will receive advice and a folder with all necessary information so that you can make an informed choice about 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. During your appointment with the ultrasound technician, midwife, GP, or gynaecologist you will be given plenty of information about further testing. You can direct all of your questions 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.

Growth echo 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 visualised. In some cases this scan is repeated at 33 weeks.

Placenta ultrasound
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.
Positioning 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. We will look to see if your baby is lying with its head pointing down or up. 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.
Foetal gender
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 reception. The price is €30.
