A Morphology Scan is also known as an 18-20 week scan. This scan is used to assess the development of your baby.
Around this time of your pregnancy, the baby’s organs and structures have formed and are able to be seen clearly using ultrasound.
It is during this scan we are able to tell the gender of your baby. Please let the technician know whether you would like to know the gender of the baby or not. If it’s possible the Sonographer will tell you, however, sometimes the baby isn’t in the right position, they are unable to see.
During the procedure we scan your pelvis with a full bladder (transabdominal scan).
How do I prepare?
Please arrive early for your exam as you will be asked to complete a pre-scan questionnaire.
It’s a good idea to dress in a separate top and bottoms, as this makes accessing your abdomen easier.
We require you to have a full bladder during this scan. Please drink 500ml of water one hour before your appointment and try your best not to empty your bladder. If you experience difficulty doing this, please talk to us at the time of booking.
You are not permitted to take photos or video during the scan. This is a medical procedure and whilst we appreciate you are excited, the health of your baby is our primary concern and we ask for your support and understanding during this clinical appointment.
Due to the medical nature of the appointment we ask that you are accompanied by one person. If you want to bring another child, it’s important to be aware that sometimes an internal examination is also required and during this, the child will need to leave the room and be supervised.
Technology and Team
Each of our practices use different equipment including Philips and Siemens machines
Your Ultrasound will be performed by a Sonographer. These are specially trained medical professionals who perform ultrasounds. The images the Sonographer captures are then reviewed by a Radiologist who will generate a report for your referring doctor.
What happens during my examination
You will be asked to lie down on a bed and your abdomen will need to be visible. The Sonographer will do their best to protect your clothing as they apply a warmed gel to your abdomen.
This gel helps the Sonographer move the probe over your abdomen and towards the pelvic/ovarian area.
To ensure we capture all the images the Doctor needs, the Sonographer may take up to an hour to complete the scan.
During a Morphology Scan the Sonographer will measure your baby’s organs and bone structures including heart, lungs, spine, fingers and toes. They will also check the function and position of the placenta. There will also be an opportunity to reveal the gender of your baby. Please let the Sonographer know if you would like to know your baby’s gender. This is not always possible for many technical reasons.
In some cases, a transvaginal ultrasound is also performed. You can read about this part of the procedure here.
The Sonographer and Radiologist will work together during an appointment to ensure all the necessary images are captured. This means that sometimes the Radiologist will come into the room. If this is the case you will be consulted before this happens.
After your examination
The results of your Morphology scan will be sent directly to your referring Doctor. Please ensure you book a timely follow-up appointment to discuss your results with them.
They will talk through the results with you. At the end of most appointments, your Sonographer will print a sample of the best photos for you to take home. You can also download copies of the images via our patient portal.
The cost of your ultrasound will depend on various factors. Please ask for a quote at the time of booking.
