ABSTRACT

INTRODUCTION: The object of this study was to assess the tridimensional cerebellar volume between genders and its correlation to other fetal growth parameters indices.

METHODS: The author carried out a cross-sectional and prospective study involving 125 normal pregnant women from 22 to 36 weeks of gestation. The assessment of fetal cerebellar volume was performed through Virtual Organ Computer-aided Analysis. The author also assessed other biometric fetal growth indices: biparietal diameter, occipitofrontal diameter, abdominal circumference, head circumference, femur length, anteroposterior cisterna magna diameter, lateral ventricle atria width and estimated fetal weight and its correlation to cerebellar volume. The Mancova analysis and Pearson's correlation coefficient were used with gestational age as independent variable and cerebellar volume as dependent variable.

RESULTS: The results showed highly correlating to gestational age, biparietal diameter, occipitofrontal diameter, head circumference, femur length and estimated fetal weight (r-value above 0.90 and p<0.0001). Comparison between genders did not show any significant difference in fetal cerebellar volume throughout pregnancy.

CONCLUSIONS: The assessment of tridimensional cerebellar volume showed no difference between genders, but there was increasing throughout the pregnancy (p<0.0001).

Key words: cerebellar volume, tridimensional ultrasound, fetal gender.
