| PURPOSE : To obtain a reference value for fetal vermian size measured with sonography.
MATERIALS and METHODS : A prospective study of normal singleton pregnancies was performed. The fetal vermian
width and anterior-posterior (AP) diameter were measured with axial image by transabdominal sonography between
18 and 37 weeks of gestation in 264 singleton fetuses. Linear regressions of the vermian width and AP diameter
as a function of gestational age (GA), biparietal diameter (BPD), head circumference (HC) and transcerebellar
diameter (TCD) were calculated.
RESULTS : Adequate vermis measurements were obtained in 264 fetuses. Vermian width was correlated well with
GA (r2 = 0.851), BPD (r2 = 0.824), HC (r2 = 0.844) and TCD (r2 = 0.859). AP diameter was also correlated with
GA (r2 = 0.826), BPD (r2 = 0.843), HC (r2 = 0.814) and TCD (r2 = 0.836). All the correlation coefficients were
highly statistically significant (p < 0.001). Nomograms of the vermian width and AP diameter according to the
gestational age were obtained.
CONCLUSION : Measured fetal vermian size was correlated well with GA which confirmed the usefulness of the rermian
size as a reference value for the assessment of vermian development. |
