What should I expect during the growth scan?

Before the ultrasound scan, our sonographer will explain the examination procedure.

This scan is normally performed trans-abdominally. In some instances, however an internal scan (Trans-vaginal) may be required to see all the necessary detail or if your womb tilts backwards.

We will always try to scan trans-abdominally first but if we need to do a transvaginal ultrasound scan then we will discuss this with you. To perform this baby scan, you will be asked to lie down on the examination couch and expose your lower abdomen.

A small amount of water-based gel will be applied to your skin. The gel will help the transducer to make good contact with the skin. The ultrasound transducer will be placed on the body and will be moved in different directions over the area of interest to obtain the required information/ultrasound images.

There is usually no discomfort from pressure as the transducer or probe as otherwise known,  is pressed against the area being examined. However, if scanning is performed over an area of tenderness, you may feel pressure or minor discomfort from the transducer.

Once the ultrasound imaging is completed, the clear ultrasound gel will be wiped off your skin. Any portions that are not wiped off will dry quickly. The ultrasound gel does not usually stain or discolour clothing.

This ultrasound examination is usually completed within 20-30 minutes. After an ultrasound examination, you should be able to resume your normal activities immediately.
