Anomaly Scan – Timing, Benefits & What Parents Learn at 20 Weeks

Introduction

The anomaly scan, also called the 20-week scan, is a key prenatal ultrasound. It usually takes place around the halfway point of pregnancy. This scan checks your baby’s growth and looks for any health concerns. Many parents wonder what to expect during an anomaly scan and why it is so important. In this blog, we explain the timing, benefits, and what parents learn from the 20-week anomaly scan. We also share tips on how to prepare and answer common questions.

What is an Anomaly Scan?

An anomaly scan is a detailed ultrasound test done during pregnancy. It is sometimes called a mid-pregnancy scan or 20-week ultrasound. During this scan, a trained technician or doctor uses sound waves to create images of your baby inside the womb. The main goal is to check your baby’s organs and body parts for any problems. This scan is safe for both mother and baby. It does not use any radiation.

When is the Anomaly Scan Done? (Timing)

Most doctors recommend the anomaly scan between 18 and 22 weeks of pregnancy. However, the best time is usually around 20 weeks. At this stage, your baby is big enough for the doctor to see important details. Early or late scans may not show all the needed information. Therefore, it is important to schedule your scan within this window. In some regions, scan availability may vary, so check with your local clinic or hospital.

Key Benefits of the 20-Week Anomaly Scan

The 20-week anomaly scan offers many benefits for both parents and babies. For example, it helps doctors spot health issues early. Here are some key benefits:

Checks your baby’s organs, such as the heart, brain, and kidneys

Measures your baby’s growth and checks for normal development

Looks for birth defects or structural problems

Checks the placenta, amniotic fluid, and umbilical cord

Helps plan for any special care your baby might need at birth

Because of these benefits, the anomaly scan is an important part of prenatal screening at 20 weeks.

What Parents Learn from the Anomaly Scan

During the scan, parents can learn a lot about their baby’s health. For instance, the doctor will check if the baby’s organs are forming as expected. You may also find out your baby’s sex, if you wish to know. However, the main focus is on health, not gender. After the scan, you will get a report with details about your baby’s growth and any findings. If any concerns are found, your doctor will explain what they mean and discuss next steps.

How to Prepare for the Scan

Getting ready for the anomaly scan is simple. Still, a few tips can help:

Drink water before the scan if your doctor asks you to

Wear loose, comfortable clothing for easy access to your belly

Arrive on time for your appointment

Bring your partner or a support person if allowed

Write down any questions you want to ask

Usually, you do not need to fast or make special changes to your routine. If you have any concerns, ask your healthcare provider before the scan.
