What is an ultrasound?

Ultrasound imaging uses sound waves that are inaudible to the human ear to produce pictures. The sound waves are reflected back by the structures in the body. The reflected sound waves are collected by the transducer (probe) and converted to images.

You can visit us for the following ultrasounds:

  • Viability scan. From 7 weeks of pregnancy we can determine if the pregnancy is progressing normally, that is, if the foetus is placed within the womb and to check for a heart beat in the foetus.
  • First trimester ultrasound
    The first trimester ultrasound is often referred to as the first ultrasound and it takes place between 10 - 12 weeks of pregnancy.
  • NT (Combined test / NT-measurement)
  • 12-weeks ultrasound
  • SEO (Fetal Anomaly Scan)
  • Ultrasound on request (DVD)
  • Gender determination
  • Specific Diagnostic Ultrasound
    These are just some of the procedures you can visit us for: a position ultrasound; a fetal growth ultrasound; or a placental location ultrasound.
  • Repeat procedures
    At times, the sonographer is not able to capture everything in the image because of the position of the baby, or other causes. If this is the case, they will make arrangements for a follow-up appointment.

Internal (vaginal) ultrasound

In some cases, we may be able to obtain a better image of the baby if we perform the ultrasound vaginally rather than via the abdominal wall. The ultrasound is always performed vaginally when it occurs between 8 weeks plus 5 days and 10 weeks to determine the gestational age. If you would prefer not to have an internal ultrasound, you should wait until you are 10 weeks pregnant. Even then there is a chance that we cannot see well through the abdominal wall, especially if you have a thick abdominal wall.

All our sonographers are trained to perform internal ultrasounds. We have agreed with your midwife or doctor that an internal ultrasound be performed if the sonographer deems it necessary.

The risk of complications through this procedure are very small. In the literature there is mention of a small blood loss from an irritated cervix. This is harmless. Should you have any concerns following the procedure, please contact your midwife or doctor.

How is a vaginal ultrasound performed?

  • The sonographer will tell you why they would like to perform a vaginal ultrasound.
  • If you have an issue with this type of ultrasound, please advise the sonographer. They will then work with you to find a solution.
  • If you have a latex allergy, please inform the sonographer prior to the procedure.
  • If you are happy for the procedure to be performed in this way, you will be asked to give your consent. Your consent will then be recorded in your file.
  • For an internal ultrasound, the bladder needs to be empty.
  • You lie on the examination table with your legs raised. Sometimes a cushion is placed under your buttocks.
  • A special vaginal transducer (probe) is used, as shown below.
  • A latex condom is placed on the transducer.
  • The transducer is inserted into the vagina, to the cervix.
  • The sonographer brings the baby in image and explains what they see.
