Abstract :

Objective: To perform obstetric ultrasonography in healthy women with uncomplicated pregnancy between the 15th week of gestation and term to determine a correlation between the transverse cerebellar diameter and the gestational age as determined by the last menstrual period and other sonographic parameters like biparietal diameter, head circumference, abdominal circumference and femur length. Materials and methods: 300 healthy women with uncomplicated pregnancy between the 15th week of gestation and term from the Obstetrics and Gynaecology department of J.S.S Hospitals, Mysore will be included in this study. The study period is for eighteen months; from october 2012 to June 2014. Gestational age for the measured TCD is obtained from the reference chart �Predicted menstrual age for transverse cerebellar diameter of 14 mm to 56 mm�. Results: TCD positively correlated with BPD, HC, AC and FL. Nomogram of the TCD shows that there is a linear relationship between the cerebellar growth and gestational age. Conclusion: TCD can be used as a reliable parameter for determination of gestational age.
