Fetal Anomaly Scan (Morphology scan)
This is a detailed examination that check for physical problems in the fetus. Fetal growth, amount of amniotic fluid and the position of the placenta will also be checked with this scan.It is best carried out around 20 weeks.Upto 95% of structural anomalies can be excluded from this scan. Basic study of Fetal heart is also done with anomaly scan and it is sufficient in all low risk pregnant women. However, in few situations detailed study of fetal heart is needed (known as Fetal ECHO).
It is important to remember that scan does not pick up all problems in the baby.
Measurement of the blood flow in the uterus (uterine artery dopppler study)is helpful to to determine risk of developing pre-eclampsia(blood pressure problem during pregnancy) and small baby(growth restriction). Measurement of the length of the cervix will help to determine risk of premature birth.
