MRI Measurement of Normal Cerebellar Vermis / 实用放射学杂志

ABSTRACT

Objective To measure the dimention and area of the cerebellar vermis and determine the effects of age and sex on the size of the cerebellar vermis in healthy adults.Methods We estimated the dimention and area of the cerebellar vermis in 360 healthy volunteers,20～87 years old.Results We found a significant reduction in the anterior-posterior dimention and the superior-inferior dimention after 60 years old.The anterior lobule area and the total area of the cerebellar vermis were larger in male than that in female.However,the analysis of age trends in the verian lobules revealed differential age related declines.Conclusion The dimention and area of cerebellar vermis reduced with aging after 60 years old.The area of the anterior vermis is larger in men than that in women.
