Early CT findings of acute large cerebral infarction

Objective To analyse the early positive rate cerebral infartion by CT scans and its influencing factors,the early CT findings and significance were emphasized.Methods Collecting statistical incidence 24 hours large cerebral infarction patients 38 cases,review films had confirmed.Results CT manifestations of 38 patients with acute cerebral infarction within 6 hours after onset were as follows: 6 cases(15.8%) were no positive sign on CT scan.Other showed parenchymal hypodensity,hyperdense middle cerebral artery sign,and local brain swelling.The total positive rate on CT scan was 84.2%.Conclusion On the basis of clinical neuro-anatomy,CT localization,and the early CT finding,conventional CT had a high sensitivity and a specificity in the diagnosis of hyperacute cerebra infaction,and provide useful information for clincical treatment.
