Anomaly Scan: What to Expect, Benefits, and Key Information

What Is an Anomaly Scan?

An anomaly scan is a detailed ultrasound done during pregnancy. Usually, doctors perform this scan between 18 and 22 weeks. It is also called a second trimester ultrasound. The main goal is to check the baby’s growth and spot any problems early. Many parents look forward to this scan because it gives important information about the baby’s health.

Why Is an Anomaly Scan Important?

First, an anomaly scan helps doctors find birth defects or health issues in the baby. Early detection allows for better planning and care. In addition, this scan checks the baby’s organs, bones, and overall growth. According to the World Health Organization (WHO), early scans can improve outcomes for both mother and baby.

When and How Is the Anomaly Scan Performed?

Doctors usually recommend the anomaly scan during the second trimester, between 18 and 22 weeks of pregnancy. At this stage, the baby’s organs are developed enough to be seen clearly. During the scan, a trained sonographer uses a special gel and a handheld device called a transducer. The device moves over your belly to create images of the baby. The procedure is safe, painless, and takes about 30 to 45 minutes.

What Does the Anomaly Scan Detect?

The anomaly scan checks for many things, including:

Brain and spine development

Heart structure and function

Face, lips, and mouth (for cleft lip or palate)

Kidneys, bladder, and stomach

Arms, legs, hands, and feet

Placenta position and amniotic fluid levels

Moreover, the scan can spot some genetic conditions and physical differences. However, not all problems can be seen with this test.

How to Prepare for an Anomaly Scan

Preparing for an anomaly scan is simple. In most cases, you do not need to fast. However, some clinics may ask you to drink water before the scan. A full bladder can help get clearer images. Always follow your clinic’s instructions. Wear comfortable clothing, as you may need to expose your belly for the scan.

What to Expect During and After the Scan

During the scan, you will lie on your back. The sonographer will apply gel to your belly and move the transducer over your skin. You may see images of your baby on a screen. The process is painless, but you might feel slight pressure. After the scan, you can wipe off the gel and return to normal activities. Your doctor will discuss the results with you, usually within a few days.

Benefits and Limitations of the Anomaly Scan

The anomaly scan offers many benefits:

Early detection of birth defects

Checks baby’s growth and organ development

Helps plan for special care if needed

However, there are some limitations:

Not all problems can be seen

Some findings may need more tests

False positives or negatives can occur

Even so, most experts agree that the benefits outweigh the risks.

Frequently Asked Questions About Anomaly Scans

Is the anomaly scan safe? Yes, it uses sound waves, not radiation. It is safe for both mother and baby.

Can I bring someone with me? Many clinics allow a partner or family member. Check with your clinic first.

Will I get pictures of my baby? Often, you can get printed or digital images after the scan.

What if the scan finds a problem? Your doctor will explain the findings and suggest next steps. Sometimes, more tests are needed.

Safety and Reliability

The anomaly scan is a reliable tool for checking your baby’s health. According to the Centers for Disease Control and Prevention (CDC), ultrasound scans are safe when used by trained professionals. While the scan is very accurate, it cannot detect every problem. Still, it gives valuable information for your pregnancy care.

When to Consult a Healthcare Provider

If you have questions or concerns about the anomaly scan, talk to your healthcare provider. You should also contact your doctor if you notice unusual symptoms during pregnancy. Early advice can help keep you and your baby healthy.
