3rd Trimester Scan

The fetal growth ultrasound is performed in the third trimester of pregnancy from the 28th week to even the time of birth. Usually, however, it is performed around the 32nd week. This examination is just as important as the 1st and 2nd trimester ultrasounds.

During this examination

• the well-being of the fetus is confirmed and any problems concerning its growth are detected.
• the anatomy of the fetus is checked.
• the risk of preeclampsia and physical development restriction is estimated.

It includes a series of measurements that are placed in specific software, which according to a large database indicate whether the embryo develops normally or not. The blood flow in the umbilical artery and in the mean cerebral artery is also examined, as well as in the uterine arteries to determine the risk of preeclampsia and intrauterine growth restriction. The amount of amniotic fluid is measured as well as the position and morphology of the placenta. In addition, the movements of the fetus are monitored, which provide important information about its well-being.

The fetus is a developing organism and therefore during this ultrasound the anatomy of the fetus is checked to detect any pathology. Specific ultrasound sections are obtained, which have been shown to have a higher sensitivity in detecting possible anomalies in these advanced pregnancy stages.

When the fetus is in a proper position, a three-dimensional imaging can be obtained (3D and 4D)
