Compression of various parts of cerebellum on healthy people by MRI Download PDF

Background: The appearance of magnetic Resonance Imaging (MRI) method has made it possible to reply neither many questions in the field of neuroanatomy more precisely while detecting altered anatomic parts of living persons at different ages. The present study was conducted to determine and record the dimensions of various parts of the cerebellum and also to compare the values obtained for dimensions with age and sex by MRI. Methods: The precondition for people to enter the study was the absence of any pathological lesion in brain on the basis of images obtained by MRI. The dimensions of target parts were calculated by the MRI-associated measuring system and recorded along with the age and sex of the patients. Measurements were recorded in mm based on selecting the largest size of the organ during the examination of axial, sagital, and coronal view. Results: All parts except the length of pyramid and the height of vermis are bigger in men than in women (P<0.05). More parts of the cerebellum in men were showing of having a significant correlation (P<0.05) with age changes compared with women and each part followed a specific pattern in accordance with age changes. Conclusion: More parts of cerebellum are bigger in men than in women and more correlation with age changes in men compared with women
