摘要
目的探讨超急性期脑梗塞的CT诊断价值。方法回顾性分析我院23例经临床确诊为脑梗塞的病例,首次均在发病6h内行CT平扫,采用TCT-300SCT扫描机。以听眦线为基线行轴位横断面平扫,层距/层厚10mm的连续扫描。结果14例CT异常表现有局限性脑沟变窄或消失4例;双侧脑池不对称8例;脑室受压变形2例。脑质密度轻微减低5例,基底节结构模糊6例。7例CT表现基本正常。首次CT诊断为超急性期脑梗塞者仅有7例,占30.43%。结论CT表现局灶性脑肿胀和基底节区结构模糊对诊断超急性期脑梗塞有重要价值,但易被忽略,应结合临床资料仔细分析CT表现,尽可能做出准确诊断,为临床早期溶栓治疗及判断预后提供有用的信息。
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.
