Efficacy of Fetal Ear Length as a Prenatal Marker of Chromosomal Anomalies: A Prospective, Multicenter Cohort Study in a Southern European Population

open access: yesJournal of Clinical Ultrasound, Volume 54, Issue 1, Page 88-98, January 2026.
Fetal ear length (FEL) correlates with gestational age and may help detect chromosomal anomalies. This study developed a nomogram for a Southern European population, showing high measurement reliability. While FEL ≤ 5th percentile increased anomaly risk, its moderate sensitivity and specificity limit clinical utility.

First-Trimester Crown-Rump Length and Embryonic Volume of Fetuses with Structural Congenital Abnormalities Measured in Virtual Reality [PDF]

open access: yes, 2017
Background With the introduction of three-dimensional (3D) ultrasound it has become possible to measure volumes. The relative increase in embryonic volume (EV) is much larger than that of the crown-rump length (CRL) over the same time period.
