Fetal Morphology
A fetal morphology ultrasound, also known as the 20-week scan or anatomy scan, is a detailed ultrasound examination that looks closely at your baby’s development and checks for any abnormalities. It is a detailed check of your baby from head to toe and is usually performed between 18 and 22 weeks of pregnancy
Why is this scan important?
This scan provides vital information about your baby’s health and development. It allows your healthcare provider to:
✼ Check the baby’s size and growth
✼ Examine the structure of the baby's organs (such as the brain, heart, kidneys, spine, and limbs)
✼ Look at the placenta, amniotic fluid, and umbilical cord
✼ Confirm the position of the baby and placenta
✼ Assess for physical abnormalities or birth defects
✼ (If you wish) determine the baby’s sex
What happens at this scan?
The procedure is performed using a transducer on your abdomen. It is a safe and non-invasive test that uses sound waves, not radiation, and poses no known risks to you or your baby. The scan typically takes around 45 to 60 minutes, but this may vary depending on the baby's position and movement. Sometimes, if the baby is not in an ideal position to view certain structures, a follow-up scan may be scheduled.

You will be asked to arrive with a moderately full bladder to help improve the quality of the images, especially at the beginning of the scan. It’s also a good idea to wear comfortable clothing that allows easy access to your abdomen.
