Anatomy Scan

This scan is normally performed at 20 weeks gestation (halfway through the pregnancy). This allows the Sonographer to assess the anatomical structures of the fetus such as the face, arms, hands, legs, feet, spine, head, abdomen and heart. The placenta is also assessed. Measurements of the fetal head, abdomen and thigh bone will be taken to assess the growth of the fetus. 

Preparation: No preparation needed.

The Procedure: The Sonographer will ask you to lie on a table. Some gel will be spread on your bare lower abdomen and a transducer will be moved over your lower abdomen to produce images. It may be a bit uncomfortable at times when the Sonographer has to obtain the best images for the most accurate measurements. You will be able to watch these images on a specially mounted TV screen. The Sonographer will be able to show you details of what they are seeing on the monitor.

Scan duration: On average, an ultrasound scan takes approximately 40 minutes. A few factors that determine the length of the scan are; the position of the fetus in the uterus, how much fluid is present around the fetus, maternal size. In some instances, a follow-up scan may be requested due to the fetus not being in a good position to visualise and assess properly. The Sonographer will explain at the time of the scan if this is required.

Post examination: The Radiologist will review the ultrasound images and provide a written report to your Midwife.

The scan images will be available to you and your family through our PACSBridge app.

You will be asked to sign a consent form before any images will be sent electronically. If you do not wish to receive these, please let us know.
