Obstetrics and Gynaecology Ultrasound : 3D / 4D

An ultrasound is an energy which uses high frequency sound waves from a transducer. These sound waves bounce back from tissues, body fluids and bone as echoes. It is used to create images of organs and structures inside the body which is safe for you and your baby. There is no radiation involved.

Obstetric Ultrasound :

An ultrasound is done early in pregnancy in order to confirm your pregnancy dates, and to give you an estimated due date. A second ultrasound will be done when you are at 20 – 24 weeks gestation, this is called the TIFFA scan. A detailed evaluation will be done at this time, checking your baby’s growth and development. A third ultrasound will be done anytime after 28 weeks to check your baby’s growth.
However, you may have more ultrasounds scheduled at the discretion of your doctor.


There is no preparation for the ultrasound.

3D and 4D Ultrasound

Initially the whole ultrasound is done in 2D. At the end of the examination 3D or 4D is done. With 3D and 4D ultrasound, some real time images of the unborn baby can be seen, but it is very much dependent on the gestation and the position of the baby. It is best to attend a 3D or 4D ultrasound with an open mind, realizing that not everyone gets a ‘as we’ve seen it on TV’ image. We will always try to get the best images in every situation but keeping the limitations of 3 and 4D ultrasound in mind avoids disappointment.

Photograph and Video

You will receive a picture of your baby in a 3D live HD view.
 A 4 – D video of your baby can be seen while the ultrasound is done.
One member of your family will be allowed to accompany you during ultrasound.

Gynecology Ultrasound

Vaginal ultrasound almost always allows clearer views of the pelvic organs
We do a vaginal ultrasound in the following conditions :
  • Evaluate a mass in the pelvis (such as an ovarian cyst or a uterine fibroid or polyp)
  • Look for possible causes of pelvic pain
  • Look for causes of abnormal uterine bleeding or other menstrual problems
  • Locate an intrauterine device (IUD)
  • To look for causes of infertility
  • Monitor infertility treatments
A vaginal ultrasound is preferably done shortly after the period has stopped. It can be done any time of the cycle if the need arises.
