The importance of volume and area fractions of cerebellar volume and vermian subregion areas: a stereological study on MR images.

Purpose: Age, gender, and body size are important factors which are affecting the cerebellar volume (CV). Many neurological diseases lead changes in CV. The aim of this study is to measure CV and the total intracranial volume (TIV) for both genders on magnetic resonance images (MRI), to calculate the CV/TIV volume fraction, and also to determine the normal values that can be regarded clinically significant by determining the total vermis area and vermian subregion areas (V1, V2, and V3).
