| Abstract |
|
The authors compared ventricular
linear ratios(Evan，s ratio, frontal horn ratio, bicaudate ratio, cella media ratio and 3rd ventricle-sylvian fissure ratio) and sulcal widening (sum of 4 widest sulci's width) of 15 patients of senile dementia of Alzheimer's type with those of 18 “radiologically unremarkable" controls. In ventricular linear ratios patients with senile dementia of Alzheimer's type revealed more marked atrophy than the controls (P ?. 05, P 0. 이，P ?. 0이), but more than half of the former overlapped with the latter. In contrast, sulcal widening of senile dementia of Alzheimer's type patients was, in comparison with the controls, not only more prominent(P 0. 001), but rarely also overlapped, therefore, it appeared to be valuable in diagnosis of senile dementia of Alzheimer's type. |
