What to Expect from an Anatomical Scan at 20 Weeks

As an expectant mother, reaching the 20-week milestone in your pregnancy is a significant event, and an anatomical scan is a crucial part of your prenatal care. This scan, also known as a level 2 ultrasound or anatomy scan, provides a detailed examination of your baby's development, allowing your healthcare provider to assess their growth, detect potential issues, and ensure a healthy pregnancy. In this article, we will guide you through what to expect from an anatomical scan at 20 weeks, helping you prepare and understand the significance of this examination.

Understanding the Purpose of the Anatomical Scan

The primary purpose of the anatomical scan is to evaluate your baby's overall development and detect any potential abnormalities. This scan is usually performed between 18 and 22 weeks of gestation, with 20 weeks being the most common time frame. During this scan, the sonographer will carefully examine your baby's vital organs, limbs, and other features to ensure they are developing as expected.

Preparation is Key

Before the scan, you may be asked to:

  • Drink water to fill your bladder, which helps with the ultrasound imaging
  • Remove any jewelry or clothing that may interfere with the scan
  • Arrive early to complete any necessary paperwork

It's also essential to have your partner or a support person with you during the scan, as they can provide emotional support and help you remember any questions or concerns you may have.

The Scan: What to Expect

The anatomical scan typically takes around 30-60 minutes to complete. During this time, the sonographer will:

Use a transducer (a wand-like device) to apply a gel to your abdomen and capture images of your baby using high-frequency sound waves.

Detailed Examination

The sonographer will perform a thorough examination of your baby's:
