A CT Findings in the Acute Period of Cerebral Infarction

-An experimental study-

Abstract

Using our model of unilateral complete infarction in the dog, we have undertaken a study of the sequential changes in CT findings during the acute period of brain infarction. It was found that low density areas first arise 3 hours after blood vessel occlusion. After 6 hours, these areas became more distinct. Significant differences in the CT values of the occluded and non-occluded hemisphere were seen 2 hours after vessel occlusion. Histological changes were also investigated.
