Transcerebellar Diameter for Determination of Gestational Age In Comparison to Conventional Fetal Biometry in The Second Half of Pregnancy

Abstract

Background: Ultrasonography can measure a variety of fetal factors, which have been linked to gestational age. It has become the most common way to check on a fetus's health. The fetal biparietal diameter (BPD), abdominal circumference, transcerebellar diameter (TCD), and femur length (FL) are the most common biometric markers used to evaluate fetal growth.Aim: Detection of the accurate gestational age evaluation method in second half of pregnancy comparing TCD and conventional fetal biometry.

“…"These biometric parameters includes gestational sac (GS), crown rump length (CRL), biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL) and fetal kidney length (FKL). However, a host of limitations with these fetal biometric parameters have been observed such as, conditions altering the skull shape thereby making BPD to be relatively unreliable after 26 weeks of gestation and other parameters such as FL has been reported to be shortened in patients with achondroplasia making it an unreliable parameter in estimating GA" [12,13]. "Race is an important determinant of fetal development, making it impossible to apply reference ranges for fetal biometric parameters from a homogeneous population to other populations, mainly heterogeneous populations" [14].…”
