Anomaly Scan: What to Expect, Importance, and Key Facts

What is an Anomaly Scan?

An anomaly scan is a special ultrasound done during pregnancy. It checks the baby’s growth and looks for birth defects. Many people also call it the second trimester ultrasound or pregnancy scan for birth defects. This scan helps doctors see if the baby’s organs are developing well. Usually, it is a safe and painless test.

Why is an Anomaly Scan Important?

First, the anomaly scan helps find problems early. If doctors spot any issues, they can plan the right care. Also, this scan gives parents peace of mind. It shows how the baby is growing. Most importantly, it can detect birth defects that may need treatment after birth. Because of this, the scan is a key part of prenatal care.

When is an Anomaly Scan Done?

Doctors usually do the anomaly scan between 18 and 22 weeks of pregnancy. This is the middle of the second trimester. At this time, the baby’s organs are big enough to see clearly. Sometimes, your doctor may suggest the scan a bit earlier or later. However, most women have it around 20 weeks.

How is the Procedure Performed?

The anomaly scan is simple and safe. Here is what usually happens:

First, you lie down on an exam table.

Next, the doctor or technician puts a cool gel on your belly.

Then, they move a small device called a probe over your skin.

This probe sends sound waves to create pictures of your baby.

The whole scan takes about 20 to 40 minutes.

After the scan, you can wipe off the gel and go home. There is no pain or risk to you or your baby.

What Conditions Can an Anomaly Scan Detect?

Because the scan is detailed, it can find many problems. For example, it can detect:

Heart defects

Spina bifida (a problem with the spine)

Cleft lip or palate

Kidney or bladder issues

Problems with the baby’s limbs

Brain or skull issues

Abdominal wall defects

However, not all problems can be seen on the scan. Some may only show up later in pregnancy or after birth.

How to Prepare for an Anomaly Scan

Getting ready for the scan is easy. In most cases, you do not need to fast. Sometimes, your doctor may ask you to drink water before the scan. This helps get clearer pictures. Wear loose, comfortable clothes. Bring your medical records if needed. If you have questions, ask your doctor before the appointment.

What to Expect During and After the Scan

During the scan, you may feel a little pressure from the probe. However, it should not hurt. You can see your baby’s images on the screen. Sometimes, the technician may need to press a bit harder to get a better view. After the scan, you can go back to your normal activities. Your doctor will explain the results, usually within a few days.
