  • Method: Per estimated gestational age

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Fetal Cerebellum Diameter transverse percentile per estimated gestational age
Diameter.transverse
Transverse cerebellar diameter (TCD) is used as a marker of fetal growth. TCDs below the fifth percentile indicate restricted fetal growth, are associated with a significant rate of fetal malformations, chromosomal anomalies, and genetic disorders, and thus further evaluation and monitoring is needed.
