Clinical CT study on functional areas of cerebral cortex in healthy old man

Objective:To find a simple and accurate method for locating functional areas of cerebral cortex on CT images.Methods:CT images of 50 cases of healthy old man were sampled randomly and the functional areas of cerebral cortex were identified by superficial sulci and gyri of brain.Results:Superficial sulci and gyri of brain were showed clearly and identified easily on CT images of the aged.Central sulcus,lateral sulcus,superior frontal aulcus, parieto-occipital sulcus calarine sulcus,circularis sulcus,ventricle and cistern were major anatomical landmarks for locating funtional areas of cerebral cortex.Eight typical CT axial images were employed to show the results.Conclusion:Superfical sulcus and gyrus of brain are marks for locating funtional areas of cerebral cortex on CT images of the aged.
