Retrospective analyses of super acute cerebral infarction on plain CT scan

Objective To discuss the diagnostic value of plain CT scan on super acute cerebral infarction.Method 23 patients were retrospective studied,which were confirmed suffering from super acute cerebral infarction.CT scans were performed within 6 hours after onset.TCT-300SCT was used,with slice thickness and distance 10mm.Results 14 patients showed cerebral shape abnormal on CT imaging.Among them,4 patients showed locally narrowed or disappeared sulci,8 patients displayed cistern asymmetry of both sides,2 patients showed lateral ventricle distortion,5 patients showed slight lower density,6 cases showed blurry basal nuclei structure.7 patients showed normal on CT scans.Only 7 patients were diagnosed as super acute cerebral infarction,with the accurate ratio 30.43%.Conclusion Brain edema and blurry basal nuclei structure are very important features for diagnosing super acute cerebral infarction on plain CT scan,but these features are easily ignored.So we should pay more attention to the CT exhibitions combined with clinical information in order to diagnose correctly and provide useful information for clinical treatment.
