Can trans-cerebellar diameter supersede other fetal biometry in measuring gestational age? A prospective study

Abstract Background Estimation of gestational age plays a pivotal role in day to clinical practice for appropriate management newborn. The trans-cerebellar diameter can predict cases variations fetal head shape such as dolichocephaly and brachycephaly or even when fetus is posterior position. Trans-cerebellar (TCD) may be useful estimation. Aim methodology To determine the accuracy estimation comparing conventional parameters like circumference, biparietal diameter, abdominal circumference femur length measurement age. This prospective, cross-sectional analytical study done Radiology Department those patients who were referred department routine antenatal ultra-sonogram checkup. Results Comparison with derived from last menstrual period indicates that there linear relationship throughout ages. There strong correlation other namely which Femur correlates well diameter. Correlation transcerebellar shows R 2 0.995 ( p value < 0.001). Conclusion best compared circumference. regression formula applied fetus.
