What Actually Happens During Your Anatomy Scan?

The anatomy scan is a detailed ultrasound, often performed around 18 to 22 weeks of pregnancy. It can take longer than an early scan because the sonographer is collecting many views of your baby, placenta, fluid, cervix, and surrounding structures.

Before the scan

You may be asked to confirm your dates and pregnancy history. Depending on your clinic and gestation, you may or may not need a full bladder. Wear something comfortable that allows access to your abdomen, and ask the clinic about any preparation instructions before your appointment.

During the examination

You will usually lie on an examination bed while gel is placed on your abdomen. The sonographer moves the transducer across the skin and records images. They may ask you to change position, take a short walk, or return after a break if baby’s position makes a view difficult.

Common views include the head and brain, face, spine, heart, stomach, kidneys, limbs, abdomen, placenta, umbilical cord, and fluid. Measurements are taken to assess growth and help document the examination.

Afterwards

A complete scan does not always mean every view is captured in one visit. A repeat appointment can simply mean that baby was facing a particular direction or that a required image was not clear enough. Your provider will explain when and how results will be shared.

Bring questions. Understanding the process can make the appointment feel less mysterious, but only your healthcare provider can interpret your personal findings.
