This ultrasound, usually done when you’re between 20 and 24 weeks pregnant, assesses the fetal growth and anatomy. This scan is used also to determine the baby’s sex and to ensure appropriate fetal growth and well-being. It can also estimate the possibility of developing intrauterine fetal growth restriction, preeclampsia, and preterm birth.

What the anatomy scan checks for:

This screening test is a detailed evaluation of all body parts and of vital organs of the fetus, especially of the:

  • Head
  • Brain
  • Face
  • Neck
  • Spine
  • Abdominal Organs
  • Chest and lungs
  • Kidneys and bladder
  • Heart
  • Limbs
  • Reproductive organs

What is the purpose of the anatomy scan?

Anatomy scan may be done for several reasons, such as to

  • Confirm the due date
  • Check the amount of amniotic fluid
  • Determine the number of fetuses
  • Examine the fetal anatomy for abnormalities and blood flow patterns
  • Observe fetal activity
  • Measure the length of the cervix
  • Monitor fetal growth

How is the anatomy scan performed?

To make picture of the inside of your body the sonographer will move a transducer across your belly. The examination takes approximately 45 minutes to 1 hour; it depends on the mother’s BMI, the number of fetuses, and the fetal position at the time the examination is conducted.

What is the next scan that I should have after the anatomy scan?

The second-trimester fetal anatomy scan detects approximately 70% of any abnormalities. Doppler ultrasound (well-being scan) is the next step you should have after the anatomy scan. It provides valuable reassurance for expectant parents and essential clinical information, helping to ensure that your baby is developing as expected.

Professor Petros Nikolaidis, always available for a second opinion, encourages expectant parents to come along with any questions or concerns they have about their pregnancy, providing as much information as possible to allay any worries they may have.
