摘　　要：目的评价CT平扫、CT灌注成像(CTPI)与CT血管成像(CTA)相结合的技术在超急性期脑梗死(HCI)中的应用。方法对21例HCI患者行CT、CTPI和CTA检查,对比观察CT、CTPI和CTA图像,分析最终病灶大小与CTPI和CTA的关系。结果 21例脑梗死患者均于发病6 h内就诊。CT平扫仅于4例中见早期表现;CTPI在20例中发现灌注异常;CTA在16例中显示异常。结论 CTPI联合CTA能够在超早期有效地诊断脑梗死。Objective To evaluate the usefulness of combination of CT,CT perfusion(CTPI) and CT angiography(CTA) in hyperacute cerebral infarction(HCI).Methods CT,CTPI and CTA were performed in 21 HCI patients.The images were compared and observed and the relationship was analyzed between the final size of the lesion,CTPI and CTA.Results All 21 patients were examined within 6 h after onset,among which,only 4 patients showed somewhat abnormity by CT scan,but significant perfusion abnormalities were found in 20 patients and angiographic abnormalities found in 16 patients.Conclusion Combination of CTPI and CTA can be useful for diagnosis cerebral infarction during the hyperacute stage.
