Pregnancy Around 18-22 weeks

Anatomy scan

The anatomy scan is a detailed ultrasound performed between 18 and 22 weeks of pregnancy. A sonographer carefully examines your baby's brain, heart, spine, kidneys, limbs, and facial features to check that everything is developing normally. The placenta position and amniotic fluid levels are also assessed. If a low-lying placenta is spotted, a follow-up scan later in pregnancy is usually recommended. The scan takes around 30 to 45 minutes. While it detects many structural concerns, it cannot rule out every condition, so results should always be discussed with your obstetrician.
