Anomaly Scan (19-24 Weeks)
The anomaly scan, commonly known as the detailed anatomy scan or the 20-week scan, is a vital prenatal ultrasound done between 19 and 24 weeks of gestation. At Sonoclinic, we utilise this comprehensive examination to assess the baby’s development and check for any structural abnormalities.
Purpose of the Anomaly Scan
The primary objectives of the anomaly scan include:
- Foetal growth evaluation: Measuring the size of your unborn child to make sure it matches the estimated gestational age.
- Detailed examination of anatomical structures: Assessing vital organs as well as body parts such as the head, chest, heart, stomach, kidneys, and limbs for proper development.
- Screening for ultrasound ‘soft markers’: Identifying slight variations from usual anatomy that might or might not be signs of potential issues.
This scan is beneficial if early screening tests were not conducted or if results suggest a higher likelihood of abnormalities.
What to Expect During the Scan
Conducted by a qualified sonographer with diagnostic experience, the anomaly scan includes:
- A 40-minute appointment to allow enough time for a thorough assessment and discussion.
- Comprehensive report and images
- Gender determination if requested.
- A complimentary glimpse of your baby in 4D upon request.
It’s recommended to share the anomaly scan report with your regular healthcare provider to ensure continuous and coordinated prenatal care.
Preparation for Anomaly Scan
- Carry with you any medical records you have
- Take a litre of clear fluid approximately an hour before your scan.
- Avoid urinating beforehand. A full bladder provides a clear view of the baby inside the womb.
- Dress in two-piece clothing, such as a top with trousers or a skirt, for easy access to your abdomen.
