Level III obstetric ultrasound (advanced anatomical detail):
The existence of all fetal organs is verified and abnormalities in the anatomical structure are ruled out through the level III or advanced anatomic detail ultrasound.
This study includes the examination of the anatomy of the heart and large blood vessels, and in general of all structures of the fetus, viewed in a comprehensive manner.
Additionally, the amniotic fluid, the placenta, and the uterus are examined, and measurements of some fetal parts are taken to establish proper growth of the fetus.
The level III ultrasound is performed in addition to the traditional measurements of the basic ultrasound or 3D-4D ultrasound, other additional anatomical measures of the body that are harder to measure and require more rigor and expertise and a more extensive and specialized training and education by the physician.
It is recommended to be done a single time during pregnancy and should be performed only after week 20 and up to week 30 at the most.
All pregnant women with high or low or risk during pregnancy must undergo this ultrasound.
It is most commonly indicated in the following cases:
- Maternal age over 36 years.
- Detection of any abnormality through level II ultrasound.
- Routine (presence of malformations or ultrasound markers of chromosomopathies).
- Positive result in triple genetic marker.
- History of children or first-degree relatives with malformations or hereditary diseases.
- Perinatal infections (TORCH).
- Exposure to teratogenic agents.
- Alterations of the fetal growth (IUGR), among others.
