Abstract: Objectives:To evaluate the role of fetal transcerebellar diameter (TCD) as an independent parameter in predicting the gestational age in the third trimester of pregnancy. To derive nomogram from sonographically measured foetal transcerebellar diameter for estimating the gestational age in Indian population. Materials and methods:Hospital based prostective study.148 healthy pregnant patient in third trimester were included in the study who underwent obstetric sonography using GE Voluson P8 machine. In all the patients following parameters were obtained - BPD, HC, AC, FL, TCD, foetal heart rate, estimated foetal weight, AFI and placental position. Transverse cerebellar diameter is obtained in the axial plane in the cerebellar view. Gestational age for the measured TCD.........
