[Abstract] Objective: By measuring normal fetal cerebellar vermis, adjacent structure and the angle value, calculate reference range, analyze development of different gestational age.Materials and Methods: MR images of 856 normal fetal heads in the middle and late pregnancy (from January 2011 to February 2017) were collected, separately measure vermis diameter, superior/inferior vermis height, area, vermis/posterior cranial fossa, vermis/anterior posterior diameter of the four ventricle, BV°, BT° to observe the vermis development and statistical analysis.Results: The overall and gestational age showed a linear positive correlation for linear growth, which the median sagittal anteroposterior diameter, vermis area and gestational age had the strongest correlation. Vermis/anterior posterior diameter of the four ventricle had the worst correlation. With the increase of gestational age, BV angle showed a decreasing trend, but BT was not correlated with the change of age.Conclusions: Fetal MR can reliably depict vermis of anatomical structure, dynamically evaluate the development of the vermis according to the normative reference data.
