This is specifically requested in women with the following history: This is a detailed scan done between 19 – 22 weeks, to check the structures of the baby, ensure normal growth and normal placental position.We specifically look for normal structures in the baby’s brain, face, spine, heart, stomach, bowel, kidneys and limbs.At our center, we understand your excitement and joy as your pregnancy progresses.

This is also called a ‘fetal growth scan’ or a ’wellbeing scan’.This is usually done in the third trimester after 26 weeks of gestation.During this scan we measure the baby's head, abdomen and limbs, and estimate the baby’s weight. We also check the position of the baby in the womb, look at the baby’s movements, the amount of amniotic fluid, and the placental position.It provides an opportunity to screen for chromosomal abnormalities (like Downs Syndrome) by measuring the nuchal translucency (fluid behind the baby’s neck).This measurement is combined with results of your blood tests (from the mother’s blood sample) to give a risk assessment for Down’s syndrome (Combined Screening).

Although most complex abnormalities are well tolerated by the baby while in utero, treatment is usually required after birth and maybe as early as in the first few days of life, often due to changes in the way the blood goes round following delivery.
