Term Description

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. PMID: 31017299
