What Is A 20-week Ultrasound?

 A 20-week ultrasound, also known as the anatomy scan, is a detailed prenatal ultrasound examination typically scheduled around the midpoint of a woman’s pregnancy. It is performed between the 18th and 22nd weeks of gestation. This ultrasound procedure is crucial for assessing the baby’s growth, development, and overall health.





Purpose of the 20-Week Ultrasound

Examination of Foetus Anatomy. The primary goal of the 20-week ultrasound is to examine the foetus’s anatomy and development thoroughly.

Identifying Potential Abnormalities. It serves as a comprehensive assessment of the baby’s well-being, identifying any potential abnormalities or concerns.

Ensures a Healthy Pregnancy. This ultrasound is a crucial diagnostic tool that aids in ensuring a healthy pregnancy and preparing parents for the arrival of their bundle of joy.

When Is The Anatomy Scan Performed?

Typically scheduled around the 18th to 22nd week of pregnancy, the anatomy scan is timed to coincide with the development of the foetus’s major organs and structures.


This window allows healthcare professionals to obtain detailed images while ensuring the foetus is developed for a comprehensive assessment.


What to Expect During the Ultrasound?

Let’s check out the steps during the ultrasound.


Preparation. Before the ultrasound, it is advisable to drink plenty of water to ensure a clear view of the uterus. Wear comfortable clothing and, if possible, bring your partner or a support person to share the experience.

Duration of the scan. The anatomy scan usually takes about 20 to 30 minutes. However, the duration may vary based on factors such as the baby’s position and the images’ clarity.

Ultrasound procedure. During the scan, a trained sonographer will apply a warm gel to your abdomen to facilitate the movement of the ultrasound transducer. The transducer is then gently moved across the abdomen, emitting sound waves that create detailed images of the foetus



Images Obtained. The anatomy scan focuses on various aspects, including

Head and Brain: Assessing the size and structure of the head and brain.

Face: Examining facial features, such as the nose, lips, and eyes.

Heart: Evaluating the heart’s structure and checking for proper blood flow.

Spine: Verifying the alignment and development of the spine.

Abdomen and Organs: Examining the stomach, kidneys, and other organs.

Limbs: Assessing the length and development of arms and legs.


Potential Findings and Follow-Up

While most anatomy scans reveal a healthy and normally developing foetus, it is essential to note that certain abnormalities may be detected. Further diagnostic tests or consultations with specialists may be recommended in such cases.


It’s crucial to approach these findings patiently, as not all abnormalities detected during the anatomy scan indicate a severe issue.


When to Consult a Doctor

You can also get in touch with the expert Gynaecology doctors at Narayana Healthcare based in your city to get immediate attention and medical support during injuries, health disorders or any other health concern.
