Abstract
Fetal evaluation from its cranial-most portions, in the first trimester, gives us a unique opportunity to track abnormalities, through the measurement of nuchal translucency (a simple fluid accumulation, without septa, in the posterior region of the fetal occiput). This is performed in an ideal period ranging from 11 weeks to 13 weeks and 6 days of pregnancy (CRL measuring 45–84 mm). An increase in the fluid in this region correlates with chromosomal abnormalities, genetic diseases, and heart defects.
