Abstract :

Introduction: knowledge of foetal age and growthis essential in management of all pregnancies. Ultrasound dating of pregnancy provides more accurate estimation of gestational age than by menstrual history. The transverse cerebellar diameter (TCD) is reliable parameter for estimating gestational age.

Methods: This prospective observational study was conducted in 300 pregnant women. Ultrasound examination for TCD and gestation age was done between 15–40 weeks of gestation. TCD was measured in transverse view of foetal intracranium. Statistical analysis was performed using suitable tests.

Results: Mean TCD at 15 weeks was 15.13±0.68mm and at 40 weeks was 44.74±2.9mm. Centiles for TCD for each GA were derived. There was significant correlation between TCD and menstrual gestational age. This study shows linear relationship between TCD and gestational age.

Conclusion: TCD is reliable method of gestational age determination
