Anomaly Scan: What It Is, Why It’s Important, and What to Expect

What Is an Anomaly Scan?

An anomaly scan is a special ultrasound done during pregnancy. It checks your baby’s growth and development. Many people call it a fetal anomaly scan or second trimester ultrasound. Usually, doctors recommend this scan to look for any problems in the baby’s organs or body parts. Because it gives a detailed view, it helps doctors spot issues early. The scan is safe and painless for both mother and baby.

Why Is an Anomaly Scan Important?

First, an anomaly scan helps doctors find birth defects or health concerns early. Early detection means doctors can plan the best care for you and your baby. Also, the scan checks if your baby’s organs are growing as they should. For example, it can spot heart, brain, or kidney problems. If any issues are found, you and your doctor can discuss next steps. This scan gives peace of mind to many parents.

When Is an Anomaly Scan Performed?

Usually, doctors do the anomaly scan between 18 and 22 weeks of pregnancy. This time is called the second trimester. At this stage, your baby’s organs are developed enough to be seen clearly. Sometimes, your doctor may suggest the scan a little earlier or later. However, most women have it around the 20th week. Always follow your doctor’s advice about timing.

How Is an Anomaly Scan Done?

Procedure

During the scan, you will lie on a bed. The doctor or technician will put a cool gel on your belly. Next, they move a small device called a probe over your skin. This device sends sound waves to create pictures of your baby. The scan usually takes 30 to 45 minutes. You can see your baby on a screen during the scan. The process is painless and safe.

Preparation

  • Wear comfortable, loose clothing to your appointment.
  • Sometimes, you may need a full bladder. Your doctor will tell you if this is needed.
  • Bring your medical records or previous scan reports if asked.

    • Most women do not need special preparation for the anomaly scan.

    What Can an Anomaly Scan Detect?

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

  • Heart defects
  • Brain or spine problems
  • Kidney or bladder issues
  • Limb or bone problems
  • Cleft lip or palate
  • Problems with the baby’s stomach or intestines
  • Placenta position and amniotic fluid levels

    • However, not all problems can be seen on the scan. Some conditions may develop later or may not show up at all. Still, the anomaly scan is a key tool for checking your baby’s health.

    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 watch your baby on the screen, which many parents enjoy. After the scan, you can wipe off the gel and go home. The doctor may discuss the results right away or at your next visit. If the scan finds any concerns, your doctor will explain what happens next. Most scans show that babies are healthy.

    Safety and Risks

    According to the World Health Organization (WHO), ultrasound scans like the anomaly scan are safe. They use sound waves, not radiation. There are no known risks to you or your baby. However, doctors only do scans when needed to avoid unnecessary tests. Always follow your doctor’s advice about scans.
